D2203 is reset every time the power button is push

[detnio]

Dear all,

I bought a D2203 two weeks ago and since yesterday every time I try to turn off the screen pushing the power button, the mobile hangs up for few seconds and it is reset (it appears the Sony, android and the PIN is requested)

If the screen turns off because no activity, I've checked the phone is on calling it. But if I press the power button to turn on the screen, the cell is reset in the same way ot happens when I want to turn off the display.

I cannot enter in safe mode, every time I push the power button the effect is the same, a reset.

Have you experienced that? How have you solved it?

Thanks in advance!

Don't worry, I have the exact same problem.  The people who sold it to me will repair it under warranty apparently.  Worrying that this seems to affect many models.

The odd thing is that sometimes, the problem just goes away.  With it then re-appearing a couple of days later.

I tried to so as well but now my device is acting like crazy. If I move an app to the SD card, the ico disappears and I have to move it again to the phone to see it.
