My M1 Note -which I bought last April- was working fine, no problem occured whatsoever. The other day the mobile was charging -using the official charger as usual- and when I unpluged it and preesed the power button to open it, the top quarter -or fifth- of the lock screen was black with a flickering white line(s) at the bottom of it.
While using the phone I noticed:
1- The flickering only occurs if the phone was locked for long enough time -I don’t know how long exactly- and only remains for a couple of minutes.
2- This flickering only occurs on a dark background.
3- The “flickering” itself isn’t the same, it depends on whatever app or action happened before the transition to any dark background, as if the action prints itself on the upper quarter of the screen, and as it’s visible from one of the screen shots the lower quarter of the Security app prints on the upper quarter of the home screen, also the flickering doesn’t occur on the homescreen with the music widget as the widget is white!
I bought the phone from Oppomart, and I emailed them with the issue and they advised me to send it to them for repairing.
Can you please advise me with the issue, what may cause it, if anyone one had the same problem or similar to it, how can it be repaired, what to expect if I’m to send it to Oppomart?
My Flyme version is 4.5.6 A, I’ve been using it since it was out, but I factory reseted and reinstalled it with clearing data and the problem still exists.
Sorry for the long post :D
