My problem started few days ago.
When i reached for my phone the screen was covered with Gray stripes, nothing more. I can use it, the sounds seem to wotk, because i get the notifications. The only way to get everything ok is to reset the phone, or press (with a bit of strength) the screen. Actually in two points.
During this abnormal activity the phone seems to be a bit laggy, sometimes it even reboots (i had it once).
The situation occurs when i have my phone locked. Nothing happens, as long as I use it. This laggines occurs from time to time, but it gets me a bit nervous.
I even wiped my phone, and reinstalled the rom. Right now I’m using 5.1. 6.0G.
So far - nothing helped.
I contacted the seller from aliexpress, but I’m afraid that he won’t help me, as I bought the phone last November.
