[LINK TO FIX][UPD 29AUG]Touchscreen Not Responsive

[undercover]

Issues with touchscreen being unresponsive.

Important Isuue usually appears at least after a week of owning the device
Quick test:
Lock device. Unlock, launch camera app in the lockscreen, take picture, try pressing back button, see if it responds straight away or with a delay. Test it with all apps on lockscreen.
Issue unlocking ? I.e dragging circle to the middle?
Bottom of a screen not responsive sometimes.
Back button slow to respond.
Apps launching when you try to change screen, i.e. phone registers swipe as a press.

CAUSE Grounding pin not touching back cover, which causes (by the looks of it) build up of static which messes up touch screen.
FIX Best to use in conjunction with fixes below.

POSSIBLE FIXes if above doesn't work, which it should, but don't expect immidiate results.
1.Shut down phone and pull battery out for at least an hour (i recommend overnight). Press power button as to turn phone on, which in theory should discharge all the left over current in the hardware.
Give it a go and let me know if it works.
2.Letting battery discharge till phone turns off,put on charge and don't touch it till it's full.


I want to thank abrown0809, eliteone, stuart0001(legendary patience ), zmfl, maschenazi, nugzo and all other people i forgot to mention for sticking with me while trying to work out FIX. Thanks to all the posters too.
I take NO credit for the fix.


Poll is here to show how many people have this problem to HTC, not to work out what percentage of users have it, as it will definitely be incorrect.
Vote yes if you EVER experienced touchscreen problems, even if its gone now.

PETITION for HTC to admit that there is touch screen problem.
All info below:

Below is the worldwide support address. There are also country specific contact pages but I'd suggest we all contact the same place so they can't keep saying they're getting no reports.:

Might be worth at least including the link below which demonstrates our issue perfectly

HT157V No issues

HT15HV80XXXX 6/1/2011
HT15BV80XXXX 6/8/2011
HT15EVXXXXX 6/13/2011 Current Device

Had big problems with the first two, both returned... Third is an improvement, however:

Seems to be a problem with the application data screen (where you can move to SD etc...) all of the data goes mental and the buttons flash sometimes causes a crash that only battery removal cures...

Back button seems to forget to work when the screen unlocks, normally returns to normal after several actions

Unlock screen is hard to unlock sometimes... helps if you are holding the device...

Screen is sometimes slow to respond

SD app icons on home screens do not regenerate after reset...

HT15JV - no touchscreen or lockscreen issues so far

Only real bug is that non HTC widgets sometimes get flickering rainbow coloured stripes but they are strictly attached to the widget and vanish once I replace the it. So this should not be a display problem especially as the HTC widgets are never afflicted.

HT15ZT and haven't noticed any issues.

HT15RT, may build and ship date

all of the above in terms of problems. unlocking problem, bottom of the touchscreen not being responsive, swipes registered as taps fairly frequently, issues with wifi cycling and never connecting, and it has ruined the SD card it came with (do the point that it gets detected by my win7 computer but crashes explorer, and on my mac it just isn't detected) as well as the 16GB microsd I foolishly swapped in from my DSLR.

Did I mention that I still am absolutely in love with the phone?

 

[undercover]

Hmmm, still a bit random.... We just need to find a common factor. If anyone spots anything in common, just mention it, even if you are not sure.

 

[cirrob]

I appreciate this thread. I am still considering purchasing this phone but the two major hold backs are the wifi signal deathgrip issue and of course the touch screen. I kinda went through this debacle with the mt4g and don't really want to go through the hassle again of finding a working model.

Did those with or without problems use a screen protector?

I left the stock screen protector on my unit and it works beautifully. Maybe because the touch screen unit is slightly displaced, static build up on the gorilla glass causes issues with some unit?

HT15RT works perfectly
