Screen problem

[balouz01]

Hello,

I have a problem with my Xperia U
When I use it, I am consulting online or playing a game, it sometimes suddenly become black.
LED is blue, the battery is ok, but impossible to debug.
So I tried to turn it back on, remove the battery ... but nothing. It vibrates when I push "power" , but the screen remains black.
it can stay like this an hour, and then it comes back ok I do not know how.

What to do in this case?

Thanks !

It's hard to pin point these kinds of issues. I don't know if this may be caused by the game you're playing or some other application in the phone, but you can try to master reset the phone or reinstall it via SUS and then run the same game again to check if you're able to replicate this.

In general, if you only experience this running a particular game I would say that it is most likely caused by the game application. So checking this with the game developer may not be an bad idea.
