I bought a L535. All updated but still having the touch problem. I have read that if I used glass protector, it would solve the problem then I tried but it did not solved, even got worse. Touch screen is less sensitive now. I have also read that the main problem is the digitizer and have to change it with new one, that produced newer. My hardware revision number is 3.0.0.0. Someones say revision 5.x phones don't have problem. I don't want to give the phone to service because I have read that they just replace touch panel with same one having same problem, so it doesn't solve the problem. Maybe if I can find the right digitizer, I buy it and try to solve by myself. Any help? Also I have heard that someones say W10M solved touch issue, is it true? However... I'm not hopeful, so I don't want to use unfinished W10M in my daily drive. Any experienced user's help please?
