Align Screen problem in qtek9100

[yule]

I bought this phone just for a month ago.but now it often has touch panel proplem,sometimes i can't point the right place which i want ,it has 1-1.5 cm's error.And if i align screen from setting again,it becomes normal.
This problem has 2-4 times one day.
What can i do?


the same problem:

Touch-screen alignment problem


--------------------------------------------------------------------------------

Has anyone else experienced the following problem:

After using the k-Jam for a while (often after a lot of opening/closing the keyboard), my screen alignment gets out of whack. Basically the touch-screen alignment moves by about an icon's (e.g. the close application icon) width to the right.

If I do a soft reset, most of the time this fixes the alignment (though sometimes I need to run through a screen alignment Wizard again to correct it).

Has anyone else experienced this? Does anyone know what might be happening?

Thanks!

Happens to me but I don't do a soft reset. I have seen this many times before in the past with other devices from different companies. What is happening is that the flexi-lead from the display to the keyboard is moving as they normally add lubicant to the flexi-cable port. What I have found that works and is quicker than a soft rest or align the screen is to simply open and close the keyboard fully.

[ikkoku]

this seems to be happening to me now. I have the WIZA200. it's weird and to me it only affects the right part of the screen (like 25%).

[SkyyBoy]

i have the same problem on my cingular 8125. the open/close keyboard trick works, but is kinda annoying to have to do all the time.
seems like i only started to have this problem after i flashed my 8125 with the qtek (stock) 2.17 rom.
i have been looking for the dopod 2.2x wwe rom to re-flash (to see if it fixes the problem), but it is no longer on the ftp :(
if anyone that has the dopod rom could upload it to the ftp, i would appreciate it 8)

[osierra]

Same problem...

[SkyyBoy]

note i reflashed with the new aku2.2 cingular rom and the alignment problem is still there... :(

Hi guys!

I have the same problem with HTC Wizard Cingular 8125 (putting in all names in case someone else searches for this thread!)

It's a total pain in the butt. I created a shortcut to the screen alignment setting on my today page. Sometimes i have to fix it once a day, sometimes every ten minutes.

I plan to reflash the ROM to the new 2.25 (or whatever is next from Summiter).

I have a feeling it won't fix it.

I will send this back to Cingular.

I'll keep you posted. Share your stories!

Thanx!

[pena_leve]

I do have the same annoying problem. for now is the second 9100 I have. tomorrow I will speak with some expert in technical stuff to know why is happening. so i'll post something about it. i'm using the rom from cingular posted by summiter (i guess this is the one i'm using...). the problem persists so... will post more. this is funny because I just had this problem again when I changed my rom from o2 to cingular.

[oakwestplayer]

this was happening to me awhile back with my tmo mda. its not the rom that's causing it. I finally got a replacment and hbavent had a problem since

[vatk]

Guys, i think the source of the problems is the case that comes with the device.
Do you all use it?
The magnets that has make the screen behave that way.
Post your feedback!

[Michael_514]

Hi there,

I just wanted to let you know that his has happened across 2.17 and 2.3 ROMS, and I don't use the case.

I am 99.9% sure that indeed it is hardware related, but not the case.

I am still waiting for my seller to help me exchange the unit....

It would be great if there is a fix!

[Jerry-S]

Hi folks, My wizard started doing this last night and i found the only way to actually use the "X" close icon was to gently squeeze my wizard from the sides.

Anyway, as I was trying to video a lightning storm, and it was 4am, I decided I would leave it for today.

I came to the conclusion that by squeezing the sides of the phone, I was gently, and ever so slightly raising the edges of the frame upward.

By doing this, any trapped dirt / grit, would not be pressing on the screen.

I have just tried this:

Take a small piece of paper, fold it tightly once and run the corner gently around the edge of the screen and under the frame.

Worked for me and could just be a simple if only temporary solution.

Try it,its free. :D

PS: Think about using the phone against a sweaty ear and all the crap that builds up.

[wig]

I have this problem on my Prophet based Jamin - same generation, but no keyboard as you guys.

Here's a thought - if this is realted to the screen squeeze mentioned above, do you all keep yours in your front pockets or in a case or what? I wonder if the unit is getting squeezed?

I keep mine in my front pants pocket all day. Not only is it warm all day but getting squeezed when I'm sitting.

Gonna try keeping it in a case for a week to see what happens. Please chime in - this is making me HATE this f'in thing.

[prestonmcafee]

I have this problem, US T-Mobile MDA, no case, but I do use a protector. My theory is soft resets cause it. At least, when I have several, it seems more likely; I have to align the screen about every third day.

For me, everything is shoved over to the right relative to where it appears.

I put a link to "align screen" on the start menu; create a file (e.g. by copying an existing link with ActiveSync explorer to your pc desktop, renaming it and editing it, then dropping it back with the new name) named something like Screen.lnk in Windows/Start Menu/Programs with this content:

22#ctlpnl cplmain.cpl,7?\Windows\deviceinfo.exe,-103

and then select it for the Start menu (Settings/Menus).

[wig]

Thanks preston - I like your ingenuity although it probably doesn't need to be said... this shouldn't be happening.

The rat bastages at HTC told me it's because I didn't install my extended ROM files. Could someone PLEASE explain how skipping Backgammon, Antivirus and PDF reader will fix this? (rhetorical).

later.

[prestonmcafee]

I only installed a small portion of my extended rom files, but it started when I had the full contingent from the original. But if there is a program that is supposed to be helpful, it would be nice to know it. Perhaps hidden in bubble breaker is the cure!

[rubbercow]

Guys, i think the source of the problems is the case that comes with the device. Do you all use it? The magnets that has make the screen behave that way. Post your feedback!

Happens to me, and I've never used the case it came with. :(

[patslaiby]

This happens to me also, but i have to say that i thought that it was the magnet in the case it came with that is causing the problem, it's been 6 weeks i stoped using the case and now i barely have this problem, i used to have it 2 or 3 times a day.

Hope someone will have a solution for this, if not can we get another phone instead?

[prestonmcafee]

I spent some time reading about this. (Is there some way to search for phrases? What makes search painful is "search for all words" turns up too many unrelated items.) First thing, every HTC device seems to have this problem. Most threads believe it is a hardware problem created by either sliding the keyboard out or inserting the stylus.

One thread noted that

HKLM/HARDWARE/DEVICEMAP/TOUCH/

contains data on screen alignment. So I aligned my screen five times and observed the data:

2078,1898 3212,650 3195,3216 839,3234 805,640
1989,1944 3255,666 3233,3235 792,3228 793,621
1987,1944 3218,663 3233,3247 783,3241 777,635
2000,1940 3238,671 3209,3249 797,3237 790,661
1965,1932 3215,640 3198,3248 754,3228 759,637

I tried changing the values to the average of the middle three values (remove the outliers component by component then average) and it worked fine, in the sense that the screen aligned. These values are

1992,1939 3224,660 3213,3243 791,3233 787,637

I of course have not been able to get the screen misalignment to appear, so I don't know for sure that this key is changed when the screen is misaligned; I will of course check if it happens to me.

If so, my idea is to create a program that edits this registry key and inserts the desired values. This program would run automatically with a soft reset, and be available on the start menu as well. That way, we could simulate an alignment without actually going through the process.

I know some people know how to create a program that edits a registry key, but I don't personally know how to do this. What is the easiest way to edit one specific key?

[xdame]

add me to the list, my wizard is doing the same thing now.

just as someone else mentioned, it happens on the right side of the screen for me as well.

not sure why this is happening but I believe it has started ever since I've upgraded from 2.24 rom to 2.26 rom. either its the roms fault or maybe my wizard has wore down and its happening coincidently at the same time.

[prestonmcafee]

I've had it with all the ROMs, whatever the first (1.08?) that it came with, although not right away, but with 2.24 and 2.26. It is either less with 2.26 or the same.

[mrinstall]

I have the same problem as everyone else. My 2 week old 8125 with the oem rom (2.25.11.1) started to need realignment after I installed the bluetooth cab and resco explorer. Since I removed them I haven't had this problem. I hope this helps.

[prestonmcafee]

I'm not using either the bluetooth cab or resco explorer, although I do have total commander. It seems like it happens to me after I open and close the keyboard a lot.

[webwhizkid]

this is happennig with my new Cingular 8125.
Got it like 20days back.
Got to realign again to make it work better.

Is there any solution for this? I get pissed off always when using. I dont normally use they keyboard.

[xbit]

I have the same problem
Qtek 9100 with spanish rom
What can we do???

[droopydave]

I bought my Cingular 8125 3 days ago. Screen started going out of alignment 2 days later. seems like is always on the right side, but that could be by that is because the scroll bar is there. kept re-aligning. now the screen just locked up completely. I gonna take it back, i guess..

darn it, it was a really cool device until this happened...

[xSoNiCcRaCkErSx]

is it just me or has the alignment problem happen to u guys after installing opera? mine did, and i dont have many progs at all on my PDA, can anyone else confirm this? soft resets dont do anything, but realigning the screen does.

[xbit]

I haven't install anything on my PDA, and it disaligns

[techsc]

i have talked with the german qtek repair service and they confirmed this to be a hardware-related bug.

The device needs to be shipped in for a repair.

This should clear any questions about this issue.

[droopydave]

I brought mine back and got a new one. So far, so good.

It is NOT sw. It is hardware...

[omalak]

Crap... does anyone know what part qtek actually replaces ? I bought mine off Ebay, and i doubt i have any warrenty on it..

I have had the same problem alligment off by an icon and cant click the x.

this does suck :(

[zeeizo]

count me in...

lets hope someone can give us solution or else our wizard might be an expensive paperweight...

[bosbik]

can we tell by the serial number which batch of units are affected?

[prestonmcafee]

If it is a hardware problem, then why does an alignment -- a software operation -- fix it?

[Giordano]

hi ...I see you r from CHina....so maybe I can help you! cause I live here too and I just fixed this prob. for 200 yuan last weekend (if you check some pages before i wrote a new topic 'bout the same issue) if you need I can help you to fix it or just give you the address of the shop i repaired my QTEK 9100... :) I was desperate when the screen started to freak out!
now everything is ok :)

let me know even on PM

[alysse]

Try this: hold the "enter" or middle selection button down & press the "Messaging" button. Works on a 8125. al

[xbit]

it works on my Qtek 9100. Thanks alysse

[bosbik]

does that fix the alignment problem?

[xbit]

it doesn't fix the align problem but it is easier to align the screen because you don't have to use the pencil to go Start->Settings-> Screen->Align

Now my Qtek works better with this problem. I have install a screen protector and now it doesn't fail so much.
Sorry for my english

does that fix the alignment problem?

No, it doesn't fix the original problem, but it makes it a hell of a lot easier to align, particularly just before I throw the phone at the wall! Happens too many times a day.

I am getting another unit via warrenty (my 2nd one) & hope that I will be done with it once and for all. When I spoke to a tech at HTC, he noted that they were hearing about this problem alot more these days & that they don't seem to know what the problem is yet. At least he was honest.

I now have a screen protector on mine, but it doesn't seem to make it any better. Wiping the whole screen from time to time seems to change the alginment a little, but not enough. Using the supplied case with the magnet or not doesn't seem to make much of a difference either.

To check the aligment while I use the phone (can't remember whether it was posted here before or not), I use "Digitizer Check." It is really handy to see how the alignment changes over time. And it is free!

I have had Palm Devices of one sort or another for many years & have never had to align more than once or twice a year. The problem is most likely in the digitizer itself and nothing more.

[bosbik]

thanks guys!.. :D

[prestonmcafee]

Does digitizer check work with WM5?

[meschle]

Does digitizer check work with WM5?

2003 versions works fine with me - after alignment bottom left hand corner reads 0,316 - good for monitoring of the screen.

[alysse]

Does digitizer check work with WM5?

Yes, It works just fine. And the "Pixel Checker" thing works great as a flashlight in a pinch!

As an update to my previous post, I received the replacement unit (3rd unit now, refurbished) and have had it for about 3 weeks now and I cannot complain about the digitizer too much. It does seem to go out from time to time, but rarely at that. Much better than the first 2 (new) units. My advice is: if the problem is chronic, get it replaced! al

[prestonmcafee]

The digitizer is interesting. When I manage to make it go out of alignment (opening and closing while writing on the screen seem to semi-reliably create the problem) the X values go from left = 4 or 5 and right = 236 to left = 0 and right = 230 or 231. That is a 5 pixel movement. There is no vertical movement.

This is something that should have a software fix, just reseting these values by a shift. Even if there is a hardware cause, it ought to be possible to create a software fix. skschema, which can program screen taps, might do the job! If I get time I will try that.

I too find (at least on my first 2 units) that using the keyboard could also make the problem worse, nevermind that the alignment seems completely wrong in landscape anyway. Why that should be escapes me as the size of the display remains the same. Only the orientation has changed.

That said, what I found was that the error "size" could change also from better to worse to better (but not always). So I am not sure that a software fix would fix the problem completely. At least in my case.

As you have seen, it always seems to be an error in the x-direction, never in y. But another sypmtom was that the pointer would sometimes get "jittery." I couldn't see past the conclusion that it was hardware after that. al

[prestonmcafee]

I created a program in skschema, that launches the align screen setting program, clicks on the 'Align Screen' button, and then tries to click on the five pluses. However, at this point it doesn't work; that program seems to require actual screen taps and not the virtual screen taps created by skschema. Moreover, even a command to show a message -- which generally works in other situations -- doesn't work once the align screen input is shown.

I suspect that when the align screen setting is shown, the virtual taps aren't possible because the program is resetting the digitizer information.

[prestonmcafee]

While I agree that a hardware defect sets it off, align screen is a software operation, that is, it is possible to fix it with software. Trackpoints are a good analogy. A common trackpoint problem is that a slight pressure sends the pointer moving even when no pressure is applied; this is fixed with software that recognizes the steady movement and adjusts for it. Similarly, whatever is causing the dislocation of the perceived screen (so that a tap at a particular point is read as a tap 5 pixels to the left), it is possible to temporarily fix the problem with the align screen setting, which is a software operation. Thus, there ought to be a way to automate this particular repair.

So far, the only alignment problem I have experienced is the left-shift, where a tap on the right side of the screen is interpreted to arise around 5 pixels to the left. Nothing except "align screen" has fixed it for me. I haven't experienced the jittery screen. Was it also fixed by align screen?

By the way, if you create a shortcut containing

22#ctlpnl cplmain.cpl,7?\Windows\deviceinfo.exe,-103

it will jump to the align screen setting, and has the right icon.

[prestonmcafee]

I now have a working version of the skschema program to reset the registry key. Soon I should be able to report whether it actually fixes the problem or not!

Here is the program:


#r(#rgget) #p(HKLM;HARDWARE\DEVICEMAP\TOUCH;CalibrationData;S Z;var1)

#r(#iftrue) #p(ok)
#r(#msg) #p(Failed)
#r(#goto) #p(end)
#r(#label) #p(ok)

#r(#rgset) #p(HKLM;HARDWARE\DEVICEMAP\TOUCH;CalibrationData;S Z;1992,1939 3224,660 3213,3243 791,3233 787,637)

#r(#rgget) #p(HKLM;HARDWARE\DEVICEMAP\TOUCH;CalibrationData;S Z;var2)
#r(#iftrue) #p(ok2)
#r(#msg) #p(Failed)
#r(#goto) #p(end)

#r(#label) #p(ok2)
#r(#msg) #p(Old Value== @var1 #R and #RNew value == @var2)
#r(#label) #p(end)
#r(#msg) #p(Over) #rmt(1000)

[prestonmcafee]

In my earlier post, I had looked at the registry keys with total commander and not realized that they are longer than I could see, and that I needed to scroll to the left to see the entire key. A typical HKLM/HARDWARE/DEVICEMAP/TOUCH/CalibrationData key is

1992,1939 3224,660 3213,3243 791,3233 787,637

This is the average taking five fresh aligns, dropping the extreme values and averaging the remaining three.

Well, I encountered an alignment problem and the program didn't fix it. Then I ran the screen alignment utility, which fixed it and changed the values of the registry key. Then I changed the values of the registry key, and the problem was still gone! I'm convinced, it is hardware and hardware alone. What is weird is why a software operation fixes it, unless there is an additional registry key being changed when the alignment is performed.

Align Screen was about the most common way to fix the problem. Sometimes for the whole day, sometimes for only a few minutes. This is about the point at which I wanted to throw the phone at the wall. Screen align never fixed the problem when it got jittery.

I am happy to see you putting all this effort into trying to automate this alignment process. But I can't help thinking that in the end, you will just need to go back & replace the entire unit or have the digitizer replaced. I have seen just the digitizer for sale on that auction site that I won't mention. al

[prestonmcafee]

I'd be surprised if I can get T-Mobile US to admit to the alignment problem, especially when my unit, which I've had for 8 months, has a few nicks and scratches suggesting a hard life. Moreover, I've changed things like the initial screen on bootup, so I'll have to go to the trouble to reflash that so that the unit looks like a T-Mobile unit, but that I can fix. The main problem is that it doesn't happen reliably; it can happen five times in an hour or once in five days.

[alysse]

Ok, my phone is an 8125 from Cingular, I don't know how t-mobile support works - Cingular can go either way depending on the phase of the moon.

But I called HTC directly instead, 877-878-6944. When the tech determind that he thought that it was hardware, he contacted Cingular on my behalf while I was on the phone & set up the warrenty return. Cingular only wanted to know if the unit got wet. Can't say anything about whatever you might have reflashed to as I am and was using the stock flash.

Oddly enough, the tech at HTC admitted to hearing a lot more about these problems & that they did not know what the root cause was. Hope that they figure it out because I would be very reluctant to give up this phone. al

[notyourdaddy]

i have an 8125 and had this issue until Summiter's last ROM he did. For some reason, the issue has gone away. i used to re-align my screen multiple times a day and now i don't think i've aligned it since i last rebuilt it over a month ago.

The ROM i'm running is the multi-installer w/ CF2. I also have the same programs installed as previous roms, magic button, slingbox, total commander and eten dialer with smart dial. i thnk thats it, but may be missing a program or two.

knock on wood. Hopefully this issue doesn't come back. This was almost as frustrating as running a 1.08 ROM.

[prestonmcafee]

I'm running T-Mobile 2.26, with only a few of the T-Mobile customizations, and the problem has been infrequent.

I was having the alignment problem pretty severely and did a hard reset for a different reason, but used SPB backup to restore the settings (so it should be a copy of the previous setup!) and the problem stopped. Now this could be coincidence. Easy enough to test.

[topcaser]

I had the same problems. It seemed to get more and more misaligned. I did also a screen adjustment more and more often. Once the problem was so hard, that i could not do an alignment any more: The device did not accept the last position of the 5 screen adjustment points :( Shit. A Reset helped to get back to the today screen - new alignment - same problem. I thought i have to send the item back for repair. Only control via HW keyboard...

Then the idea: i started screen adjustment and tapped anywhere but not on the focus of the points. By doing this i could tap also the fifth point and the device accepted it. Happyyyyy. Second i started the adjustment at once again and tapped the five points corectly. The deveice worked well up to now - i dont know if the problem is gone completley ( i dont think so) but i had no problems since 3 weeks or so.

BTW: The problem occured after several months working well with the same ROM. If i have again these problems i will further investigate some things like the SW workaround: i think this is a good approach to correct the values. Nevertheless: I want to know how the problem is caused:

The touchscreen reports the coordinates to the OS. With a simple command one is able to react to this taps. Since the problem is independent to certain programs it has to be reported the wrong coordinates to the OS. Or is it the OS itself. but the problem is there on many devices on many ROMs - also on old WM03 ROMs. I am not sure at all.

I have to make more thoughts about it...

[prestonmcafee]

Please keep us informed of your thoughts.

I now haven't experienced the problem for several days. What is peculiar about this is that I it was happening about hourly, then I did a hard reset and a full restore with SPB Backup, and the problem didn't recur. That doesn't sound like a hardware problem!

But I'll see if this fix works the next time.

[mikechannon]

Hermes 200 626 Alignment issue cured.
Iv'e been through all the try this try that and you get fooled sometimes as things appear to work for a while and then one day your back with the problem again. See below for my solution or at least explanation for this erratic problem.


First 2 weeks fine then progressively worse - 1 cm out and realignment every few minutes.
BUT have cured problem by dismantling and placing cushioning between screen and case. Also there are poorly gripping plastic clips holding screen in place - I firmed these up as well. problem has vanished. What a relief and absolute proof to me that it was the hardware. Believe me those retainers on the screen were sort of clicking on and of the back of the screen - leading to the now it works now it doesn't syndrome. The clips are only at top and sides and only a fraction of a milimeter was enough to loosen and tighten the grip. Ties in with those who felt as device got hot the problem got worse. A bit of heat would easily be enough to loosen/slacken the grip. It also ties in with those who found that as they pressed and squeezed around the screen area the alignment changed. Now when I do this there is no alignment change - rock solid.
PS. If your a bit technically minded try it - BUT say goodbye to your warranty!

Dismantling is relatively easy with some experience be a little careful of Mylar connectors between main board and keyboard and between screen and digitizer. Watch out for tiny screws on screen area boards and use a good screwdriver set.

PPS you can also fix loose keyboard locking while your at it but that's another story.

Mike

[prestonmcafee]

Can you post pictures of your dismantling, fix and reassembly?

[enmatt]

mikechannon, that's cool.

Although, I'm wondering about one thing. I've recently upgraded to the ROM released by risidoro here, http://forum.xda-developers.com/showthread.php?t=276700 . BTW I'm on a G3 based Wizard.

What I found was the problem disappears if I don't OC the Wizard. It seems to return if I OC it to 240MHz. Wonder what that's about. Right now running it at stock speed without any screen issues.

Anybody got any ideas as to why OC'ing seems to misalign the screen?

mikechannon, that's cool.

Although, I'm wondering about one thing. I've recently upgraded to the ROM released by risidoro here, http://forum.xda-developers.com/showthread.php?t=276700 . BTW I'm on a G3 based Wizard.

What I found was the problem disappears if I don't OC the Wizard. It seems to return if I OC it to 240MHz. Wonder what that's about. Right now running it at stock speed without any screen issues.

Anybody got any ideas as to why OC'ing seems to misalign the screen?

My thought on this is that if you OC or run a few processor applications you will generate just a little more heat which could cause the issue. It's not a unique problem and happens with a variety of diff. pdas. Also, it is possible there are two problems - some with a software/digitizer problem and others with the problem I've outlined. Some may have both. The majority I've read about seem explicable by poor screen clips and gasket - even though the owner thinks it's software.

Can you post pictures of your dismantling, fix and reassembly?
Happy to do this but stuck for a camer at present.

You are right about the hardware issues. However what boggles me is that this glitch seems to fix itself if you do an align screen from the screen controls. I mean, how does software fix what essentially is a hardware issue.

The answer I believe is that adjusting the screen alignment does not fix the alignment, all it does is adjust algnment to the screen position your are currently at. In other words when the screen moves just a tiny bit the next time it'll be off alignment again - so you re-align to the new screen position and as soon as the screen moves again the alignment will need re-doing i.e. an endless cycle of the screen moving a using software to compensate for the physical movement of the screen. The software is fine it is able to compensate for the changing physical position of the screen, but the screen keeps moving (and it only takes a fraction of a millimetre to throw things off).

Trackpoints have this issue, slight physical pressure makes the pointer move, and this is fixed with software that detects and stops the movement. So that is a software fix to a hardware problem. However, the odd thing here is that the movement isn't very far. Moreover, every time I have the problem, the right side is about 5-7 pixels off and the left side right on. So it is like the screen has been stretched, and by more than a millimeter.

Yes, and your experience is similar to most folks with the problem. Internally the right side of the screen has the digitizer just below the bottom right corner and a Mylar cable looped around to connect to it. The pressure inside the Screen housing is therfore not even all round the screen and I suspect is higher on right side. I've seen some posts taht suggest the entire issue is caused by pressure on the digitizer as opposed to a loose screen. However firming up the screen will also reduce movement against the digitizer.

i have the 2.25 version, and it does the same thing, only it's worse.... the center part of the display won't recognize tapping on it.... when trying to draw a straight line through the center area it will either start straight and then curve and then it'll go straight, or it just won't draw at all.....when trying to reallign the tap on the center cross won't be recognized, like that area just lost sensitivity..... i've had my 8125 for a week, and it's in south america, where we have no cingular, what can i do?... some have said that opening fully the keyboard helps, or rubbing a finger evenly through the screen will fix the problem definitely, but mine won't.... please help me out, i don't want to send it to the us for replacement.....

Hi guys!

I have the same problem with HTC Wizard Cingular 8125 (putting in all names in case someone else searches for this thread!)

It's a total pain in the butt. I created a shortcut to the screen alignment setting on my today page. Sometimes i have to fix it once a day, sometimes every ten minutes.

I plan to reflash the ROM to the new 2.25 (or whatever is next from Summiter).

I have a feeling it won't fix it.

I will send this back to Cingular.

I'll keep you posted. Share your stories!

Thanx!

I upgraded my ROM to Molski's 3.0.0.0, and I haven't had to adjust my alignment, not once, since I did so. I used to go out of alignment pretty much daily.

I put a note in the Molski thread but no one responded either way.

To be fair, I was probably at a low point at the time I upgraded, but that has been weeks now, and still no readjustment.

I just bought my tmo mda on ebay around Jan 1'07. I just started seeing the screen align problem. First time was on right side, last night. Though it was off by a few pixels to the right of the screen, so could not tap scroll bar at all. Second time, today around noon, was just to the right of the middle of the screen. The alignment was off by a few pixels to the left.

Hello again,

Well, my screen went out of alignment again after about 1 hour. Then I tried the "Stick paper between screen and case to clean" trick....Well, it worked. It was out of alignment, then after cleaning it was fine. With no need to go to the screen align utility. We'll see how long it keeps...

BTW, I used the corner of an average business card...

Two and a half months later, I still have never gone out of alignment. If there is a hardware problem, it has a software fix!

Hi guys , I've had the same problem . I was initially dead worried that my precious little device had turned bad for good ! then I realized it only happens if I used the case . My guess is it's the magnet .

Try placing a clip or a stapler pin inside the case and you will see how powerful tha magnet is . The poor digitizer doesn't stand a chance !

My advice , put the phone in the cover so that the screen faces the belt clip !

Yep , that should do it ! :)

I've read somewhere that it's the crews behiend the screen are too tight and when the Wizard is in your pocket the screen becomes dis aligned with the heat or something like that.

I've been baffled by this problem for some time and I finally found a fix! As stupid as this solution sounds, it worked for me so I want to share it. To fix the allignment problem, just rub your thumb around firmly on the touchscreen. Make sure you push in all four directions. That's it! Of course you will leave greasy finger marks on your screen but that is a minor issue compared to a malfuctioning touchscreen.

I got this suggestion off another forum (HTC Web, I think) but there was no explanation as to why it worked. However, multiple users reported this as a PERMANENT FIX to the screen mis-allignment. My hunch is that the touch screen somehow gets pushed out of allignment and the corner/edge gets slightly pinched or squeezed by the case. This pinching could cause errors, or in my case, complete failure of the touchscreen. Rubbing the screen should eventually put the touchscreen back in correct alignment.

My screen was so bad that it would not register any touches for up to a couple hours at a time. Not even a reinstall of the factory ROM would fix this problem for me. But the screen rubbing did the trick! I thought I'd was going to have to send it in for a new touchscreen but now it is working well.

hi guys.i had screen aligment problem with my kjam and i sent to service.they changed screen and speakers.so far so good.

I'm trying that now, but using post it note . Using the sticky side up (not getting sticky on the screen itself) and jamming the paper in a bit, then running it across i'm getting a HUGE amount of dust/crap coming out onto the paper. It's amazing. So far no alignment issues.

I tried the card trick on my 8125 and I will see how it goes. A can of compressed air works nicely to blow debris out from around the screen after using a card as well! :)

No, it doesn't fix the original problem, but it makes it a hell of a lot easier to align, particularly just before I throw the phone at the wall! Happens too many times a day.

I am getting another unit via warrenty (my 2nd one) & hope that I will be done with it once and for all. When I spoke to a tech at HTC, he noted that they were hearing about this problem alot more these days & that they don't seem to know what the problem is yet. At least he was honest.

I now have a screen protector on mine, but it doesn't seem to make it any better. Wiping the whole screen from time to time seems to change the alginment a little, but not enough. Using the supplied case with the magnet or not doesn't seem to make much of a difference either.

To check the aligment while I use the phone (can't remember whether it was posted here before or not), I use "Digitizer Check." It is really handy to see how the alignment changes over time. And it is free!

I have had Palm Devices of one sort or another for many years & have never had to align more than once or twice a year. The problem is most likely in the digitizer itself and nothing more.

I was dying with this Screen Alignment problem, few times back i've just installed the Dizitizer & till now screen is working well even i can tap the screen with my finger. hope it will work perfectly.

And once again thank you for this solution.
