I've done a good bit of research and I'm surprised that nobody has asked how to fix the crappy multi touch streak has.
Here are the issues it currently has (tested in MultiTouch Visualizer 2):
-Does not read second touch until the finger has actually moved
-If you release the second finger without moving the first the phone will not recognize that the first finger is still touching the screen until you move it
-The screen will not register more than 2 touches (the app will just turn the screen blank when a third finger is placed)
So here is my question: Does anybody know of a way to modify the multi touch (response and number of points) through any means like build.prop or perhaps a modified kernel?
Same problem. Still looking for solution. It`s problematic with emulators and most games.
Hi guys, I have a very strange problem that has been occurring over 3 different firmwares on 2 different S2's. If i swipe my finger over the top right hand corner of the screen (like where the time, battery %, etc. is) the brightness of the screen automatically increases to either half the brightness bar or 3/4ths, or sometimes 90% of the bar.
I have tested this on 2 phones in several different apps, home screen, etc, and even in landscape mode (landscape mode shifts it to the top left of the screen which would be the top right of the UI) which leads me to believe it is a firmware problem and not a hardware problem. However considering it was an issue on my brother's phone running stock KG6, my phone running Sicopats rom based on KH3, and his phone after flashing stock KH3 then on cognition 1.5.1, i am confused as to how all of these rom's could have this issue.
Is it because the issue hasn't been addressed? am i doing something wrong? please help me out guys i know this seems like a small issue but now that i've noticed it it's bothering me quite a bit
It's a Samsung feature. Sliding your finger on the status bar while in manual brightness mode adjusts the brightness of your screen.
I thought so too at first but its so unpredictable that I dismissed that as a possibility. do you know if there are any mods which disable this?
So i just installed the stock cm9 rom on my new touchpad and the touch screen is not usable at all. For example when i try to type it types a hand full of random letters with it in less then a second. If I hold my finger down anywhere on the screen (even if its not the keyboard) the device will start clicking random points on the screen.
Does anyone else have this problem?
Hi,
my Atrix is behaving strange lately, but i just don't want to let go my old lady... so anyone has any idea re. root-cause of the problem?
situation
i got aware that the touchscreen had stopped working for a particular row, next to the volume control buttons. for me, it's been clear: hardware failure.
i wanted to see the symptoms in detail, hence installed a diagnostic app to check the touchscreen and identify the "dead zone" properly.
SCREENSHOT #1
but
when playing around, in the endeavor to paint all my screen blue, swiftly swiping my finger across the touchscreen. after a while, the phone's reactions became sluggish, and the home/back buttons would not bring me back to my home screen. so i switched the dialogs off and on again (power button). and the home/back buttons returned to work fine.
BUT
to my utmost surprise, the touchscreen problem had gone!! no more dead areas in the touchscreen!
SCREENSHOT #2
only after a while, the problem returns and the very same row is dead again regarding touch inputs.
Amazing! and this is fully reproducible! it's necessary for the app to react sluggishly (which is only randomly achieved), and the home/back buttons to stop working, to temporarily 'heal' the touchscreen.
So it's not a hardware, but software problem?
what's your opinion?
BTW, I am running a rooted stock release, european version, atrix 4g.
cheers

There are no screenshots in your post.
Also, there are plenty enough threads about this, was yet another one really necessary?
Problem Cause - Solution Approaches
OK, sorry. What's the solution: 1 - 2 - 3 below?
1) Sounds reasonable - bad contact in a connector:
Emerging Hardware Issue: Touch Screen Dead Zones
2) This does not help a lot. Seems only for custom ROMs:
touchscreen is off only at the bottom of the screen
3) That's not very helpful - there's no description what the idea behind this mod is.

Click to expand...
Click to collapse
4) Do what most of us have done, which is replace digitizer or replace device completely
Hi, recently I started facing touch screen issues.
My touch sensitive buttons aren't responding and sometimes the lower part of the touch screen is unresponsive. That is fixed with a gentle squeeze and a lock and unlock. Sometimes the touch behaves as if I'm using two fingers than one (scaling when trying to fast forward video using one finger )
Sometimes the entire touch screen goes unresponsive which is fixed with a lock and unlock. The scroll becomes dead slow too sometimes. Again the fix is the same.
I'm not sure if this is a firmware issue or hardware issue. The rest of the touch works fine.
I'm using a Gionee P6
I tried to trouble shoot using the secret star codes but unfortunately the menu is in Chinese for this device.
If someone could help before I send it in for repair which will take a long time I'd appreciate it
EDIT : I Was able to use the touch screen testing from the diagnosis hardware menu and there are no dead points. Every part of the touch screen responds. Except when I actually use them in Android
