Hello,
The problem in my Samsung appeared more than a month ago. Initially, the HOME / BACK button did not work. After a week, everything returned to normal. Two weeks ago the touch fell completely - no reaction in any place, you could not even turn off the phone so I had to wait for it to discharge. After these two weeks, I recharged the phone, lay for about 2 days unused and suddenly the touch began to work. The problem is that sometimes it hangs, that you can not do anything, however, after locking and unlocking the screen everything returns to normal: o Where should you look for the reason ? Is the display itself already finished, maybe some tape or the software itself? The phone has been in use for over two years.
