Sony Xperia XZ Premium - Blinking Screen

[JoKathe]

Hi, Just a quick question. Has anyone experience the screen blinking while using the phone? What is currently happening is that sometimes, while using my phone, the screen keeps on blinking. It can only be removed once I restart my phone.

Hello., can you do some quick troubleshooting ?

1. try to restart the device in safe mode

2. perform Xperia Diagnostics. go to settings>about phone>diagnostics

are using any screen protector? or cases?

Same with my XZP, i noticed that too. Try to change brightless while it is blinking, after i did that it spoted, without restarting phone! but anyway, it's some soft bug i think.

Hi,

1. try to restart the device in safe mode - Done

2. perform Xperia Diagnostics. go to settings>about phone>diagnostics

 - Done, no problems found

are using any screen protector? or cases? - Yes, tempered glass with a leather flip card case

It may be, but my question here, I experience it on any location, whether I am outside walking in the sun, or at the office with a low lighting environment. Is it still possible for it to be that issue?

[najodleglejszy]

is it actually blinking, i.e. the brightness is getting lower and higher, or is it only colours that are changing? if it's the latter, then my bet is on Assertive Display.

It is blinking probably the brightness going up and down. I can see the home screen going lighter > darker > then lighter again, but the colors remain unchanged.

The 120 build introduced a bug in the Qualcomm Adaptive Brightness which causes that. We're hoping Sony will fix it before the next century so stay tuned

I have the same issue also and the problem is still there after the 137 software update last night
