I think it is not bad to share our issues after update on ICS.
Please no discussions, just a list, when possible!!!
Because i had the full program with restore,factory reset, sus, troubleshooting chat with Sony.
The support advised to sent the device to them an let it downgrade on Gingerbread.
So we need no more suggestions, more an update
Ok, mine are:
wifi, works for only seconds when i enable it
camara button, the only function is after switches on the camara, the flash light lights on but no picture
The issues that you report is not something that I have seen before or as something general for the ICS software. So I suggest that you have your phone examined and fixed at an repair center.
