iPhone 5c locking on its own
Hi all,
I have had an 16GB iPhone 5C for almost 2 years, have recently upgraded the software to IOS 8.4.
Have looked after it with a protective case, but in the last week it has started auto-locking on it's own. This has got worse as the days have progressed until now when I can not unlock it and navigate for more than a few minutes before it locks itself. The screen goes black and when I press the button tho get the lock screen up it captures a picture instead. On the odd occasion the phone has gone as far as switching itself off and telling me it needs charging before I can restart, when there is 28% battery left.
I have switched the Auto-Lock option in phone settings to 'Never' but it's made no difference. The phone has started locking during calls, cutting me off from people and doing the same when dialling cancelling the call.
At the end of my tether here and would really appreciate some advice.
Best Wishes
