i just downgraded from ios7beta1 to ios6.1.3 on my iphone 4 gsm.
at first is did a normal restore without dfu and it had some issues. so i update back to ios7, then used the dfu method to do a restore, restored my backup file. and all seems good, only problem is that my proximity sensor has stopped working. it doesnt turn the screen black at all. i googled for a fix and i did a reset for all settings but still the issue persists. any idea on how i can resolve this?
