Just now the phone has decided to stop responding completely. It wouldn't switch off without taking the battery out then switches on again fine, but to the same problem. I've had it where the touch screen won't respond at all before and fixed that fine, but now neither the touch screen or any of the buttons will do anything while switched on.

The power button switches the phone on but only when the phone is completely turned off. If the charger is plugged in then it won't work,

Any help would be amazing, thanks.

Edit: Just noticed if I push the volume button really hard it brings up the volume control but thats all.
