I also flashed almost every ROM I could think of trying to see if i t fixed the issue however it did not. I always flashed the unlock for the ts after so it would not stick in the new Roms hoping that it would get better. I have also done a full factory reset and wipe without any luck. Currently I'm running Android L lpv81( the second release) and I'm not ropted. I was using 4.4.4 with twrp earlier but it doesn't matter as long as I can get this touch issue fixed.
I looked around the forum for a while and used every fix I could find but none lasted long enough for me to enjoy it. I would really appreciate any help with this, I'm not afraid to mess around with some things to fix this issue.
