[MOD][4.4.2-Touchscreen-Issue-Fix]

[Shaky156]

While updating and using the latest Android OS from Nvidia for the Tegra-Note, I noticed some issues with the touchscreen.
Browsing the forum I noticed other users had issues with this too
So I have released a fix for this issue

Issues fixed:

Touchscreen unresponsive
Single click -> double clicks
Touching the screen in one area while, touchscreen thinks youre touching in another area

Untested:
Using stylus and touching from edge of screen to centre loses touch focus from stylus

Requirements:

Unlocked bootloader
TWRP Recovery

Installation:

Download touchscreen fix from the link below
Reboot into recovery using "adb reboot recovery" or Volume up and power button
Locate zip file and select install or "adb sideload locatetotouchscreenfixzip"

Download Link: http://d-h.st/PkX​

4.2.2 or 4.4.2?

Hi Shaky, you said the latest version of Android but your title says "4.2.2" . Do you mean 4.4.2?

Like everyone else I have these pesky touchscreen issues and I am hoping you mean 4.4.2 because that's what I got.

Awesome!

Excellent stuff, my friend. I'll certainly be flashing this once I get home from work.

no problem, I think I saw a few people complain about GPS on this device... What is wrong with GPS? I shall take a look later

GPS Blows

Actually, I'm not too sure since I don't really use GPS on my tablet since I always have my mobile handy but I did give it a try this morning and I couldn't lock on to any satellites. Tegra Note 7 found 3 satellites and locked on to none. Granted I was indoors at time but comparing to my Galaxy S4, I found 21 satellites and fixed on to 7 of them. I used GPS Status to get this information. I also used Faster GPS to assign an NTP server but it didn't do much.

Hopefully that's helpful, maybe people who have tested this extensively will chime in soon to point you in the right direction.

Post your feedbacks guys ! Does this works 100% if we are in plam rejection mode and we slide our finger from left or right side of the screen does it reads it as stylus ?

what exactly does this "fix" do? It would be nice if there was a description of the actual functionality and how its achieved. Right now, i have no idea if this is going to help me with my absolutely horrible palm rejection, and poor stylus performance issues, or help people who are having ghost clicks, or if its going to help the end swipe people, or the people who randomly have no touch responsiveness. Looking at the archive, it looks like you're writing new firmware, is this just simply the firmware from 4.2.2? or did you modify it in some way to fix the problems that are current. A little transparency would be awesome here, im not sure whether to try and contact evga, or just throw this piece of crap against the wall and cut my losses.

*edit* if i seem abrasive, im really sorry. The camels back broke tonight, and im literally seething. I expected better from nvidia. Either I can't believe there are either so many stupid people in the world, or Im the idiot who did all my updates right out of the box, and don't know what im missing. If it can be better than this, i want THAT experience.

Op updated. Take your complaints to EVGA, or nvidia, not me. I have simply provided a fix for touchscreen issues.

Shaky, as i said, not directed at you. I'm just frustrated. I'm directing them directly at the forum where other people who had my frustration may have found a solution. I mean, its a forum right? Your fix unfortunately has not helped in my case, perhaps I have bad hardware. Having unlocked to try your fix im sure nvidia and evga are likely out of the question, but I'm resigned to just using this as a 7" e reader.



Thanks for replying back to the thread anyway.

I've had a couple of days or so to test this now. First off, this mod doesn't seem to be a 100% fix yet. But, I have to say that the responsiveness of the touchscreen is improved when it DOES work.

The problem that still occurs the touchscreen becomes unresponsive for some seconds still, particularly if I come from a resource taxing app (e.g. a game or something), I close the screen and open it again. The screen becomes unresponsive when I key in the PIN, for example, I'd key '1', it won't respond, so I'd key '1' again, still nothing so I repeat then finally the touchscreen responds by keying in a million '1's' lol. So usually, I have to type my PIN really slowly to give the touchscreen time to detect my presses. Usually, I'd have to reboot to get proper touchscreen responsiveness.

I still have a problem with the stylus where it becomes unresponsive with the stylus only or palm rejection mode on. If I have my palm pressed somewhere across the edge, sometimes, the stylus stops writing.

With that said, there has been improvements in responsiveness with this mod but that's when it DOES work. Meaning, flinging between screens, touch typing, and the stylus all works better when it works. Does that make sense? LOL.

I really hope NVidia and EVGA get's on this soon.

Thanks for the feedback, can you provide a log whenever that happens? enable usb debugging and in terminal (cmd) "adb shell logcat > logcat.txt" without the quotes. I think I know why it doesnt work 100%, but require logs to confirm.

 

[Shaky156]

Btw you guys are aware, settings -> directstylus -> set timer to activate finger touch after pen use -> disable touch only during pen use or select 3 seconds

Sorry, been busy

Hey, I haven't had time yet. I've been spending too much time away from home these days with work and all so when problem happens, I am without the ability to get a logcat file. I'll get you a log as soon as time permits.

BTW, just two days ago, I had a related problem occur and instead of rebooting what I did was just play around with the device so I can give you a better description of what happens. I say "related" because I think last time I described what seemed like lag after touch presses and problems with the palm rejection.

Scenario:
1. I was plugged in charging.
2. Unfortunately, I cannot recall what I was doing or what app I ran before the touch screen problem occurred.
3. I brought up the App drawer and when I tried to swipe left to get to the next screen of apps, it automatically just swiped back to the previous screen.
4. I managed to open Google Now where my keyboard popped up automatically, characters started popping up on the text box as if my keys were being pressed.
5. I rebooted and didn't bother to wait to see if the problem would fix itself.
6. Things that might be important: I use Nova Launcher Prime and Swift Key.

Like I said, if I can somehow get lucky to have the problem happen just when I am at a PC, I'll send the logcat file ASAP.

Thanks for the effort, Shaky.

Thanks if I can get a log I can check it out, I think it will be fixed when I release something else, have been very busy so a lot of delays...

Sneak peak...

(in the voice of Kyle's mom) Wha-wha-what?! Someone is doing a custom ROM for this thing?

It's about time, I can't wait! The only thing that has irritated me about this tablet is that there is almost no development interest in it, which is weird since it's both unlocked and inexpensive. Huge thanks, and I can't wait to see the TN7's first custom rom!
