[Q] Touchscreen does not react properly
My Galaxy Tab 10.1 is giving me a hard time since a few weeks.
I run the CM 10.1 nightlies on the device and have the following issue:
The touchscreen does not react to my finger properly. Sometimes it works, but then doesn't react anymore. I then press the power button, to send it into sleep mode, then press it again to wake up. the device reacts then like 99% of the time to unlock it. but after that its just a pain in the a**. As far as I can remember, I did not change the ROM when this happened, but since then I tried dozens of different nightly versions, even ones that I know they worked before.
The strange thing is, that it seems to be dependent on the position sensor, because when the tablet is on a flat surface, and is not moved, it works the best. Not 100% but like 80% of the time. But when I hold it in an upright position, or just in my hands, not flat on a table or something, it reacts to like 5% of my tries...
I have been searching on xda and on google about that problem, the most matching one was a driver issue that occurs after like a minute or when a graphic intense app has loaded. They provided a kernel fix, which just made my tab boot into infinity and never reaches the lock screen. after factory reset it boots again, but the problem still exists.
hope somebody can help, because I love my Tab and I can just not accept the fact that it could be a HW issue, since it works 99% of the time on the logon screen, and due to the fact of the position sensor being involved...
thanks in advance! please make me happy again!
