Xperia Arc black screen

[#1]

Hi all,

I have my Xperia Arc since beginning of September. And sometimes, I get a black screen on my phone. Unable to restart the phone or do anything with it. The only way to manage this is to remove the battery and place it back. Then I can restart the phone normally.

Last time, my battery was at 32%. I have Androïd 2.3.4 and use firmware version 4.0.1.A.0.283

Any idea of what can cause this? Is it the battery itself?

Ok, I tried this. We will see in the next days if it happens again. Thank you for your reply.

But now, I have a huge question : Firmware version 4.0.2.A.0.42

What is this? I didn't even knew that version was available.

[uliwooly-wooly]

it seems to be a newer version of the firmware, it doesn't seem to add anything new to it.

[uliwooly-wooly]

the only big difference are few extra apps

Sorry, I couln't reply earlier.

It happend 2 times again. But there was nothing wrong with the phone before. It just stops.

I have absolutely no idea about what is causing this. But good point, once a month is not too often for me. Thank you, anyway.
