screen blackout

[nick5437]

This phone seems to be racking up the problems after about a month of use....

All of a sudden, whenever i phone someone or get an incoming call, when i call/ accept phone call, the screen locks and goes black but the call is still being made/ i'm still able to talk to the person on the other end but when i press the power button the screen does nothing for about a minute then it goes back to normal

Would really appreciate if Sony actually does something about this as the last complaint about duplicated photos from about 2 weeks ago still has no update! And stop sending me email's about my status as 'newbie' or 'first time poster'.....i don't care, i want solutions for these constant mounting problems

[nick5437]

oh, and when i hold down the power button (trying to turn it off) when it is like this, all i get is a tiny vibration then back to nothing. The main problem with this is that, if i ring someone and they don't answer, i can't hang up when it goes to their answer machine

It's sounds like a memory or CPU usage problem and so the phone have a lot time to respond...

What is the firmware version installed?

Have you tried to reset device or look at memory\CPU usage?

[nick5437]

I don't know how to find what firmware i have, no i haven't tried resetting it, it's only been 1-2 months i shouldn't have to reset and lose everything already....

Go to settings, last voice is telephone info and here you can read Android version and Build release (the last voice).

Do you have a case or screen protector on the phone?
