Z3 tablet compact (sgp621) flickering display

[Ahmed93]

My z3 tablet's screen is flickering from the update 4.3 to 5.1.1 it's so annoying i tried 3 different firmwares with no change, i did a factory reset for 5 times, i did everything and it's still there.

P.S:i bought this tablet from dubai, and now i'm in egypt. It's the worst support ever here from sony, they ignored me, and after that they told me the can't solve this issue. PLEASE HELP

I'm sorry to hear that, but this seems to be a hardware issue, and has to be addressed by your Local support

Did they gave you a reason as to why they can't help you?

There is a very long topic on xda talking about the same issue on the z tablet and z2 tablet, alot of users send their tablets for repairing and the issue remains so they admited that it's a software bug and finally found a solution by disabling HW overlays i did it and it seems to be working i will wait for a few days and see, here's the link please check it http://forum.xda-developers.com/showthread.php?t=2588949

PS: i have my tablet for a week and i noticed this flickering after two days of normal usage, it suddenly begins to flicker for 2 minutes or 3 minutes and suddenly dissappear, it doesn't happen alot but when the display begin to flicker it's so annoying
