iPhone 5c - Bluetooth Spinning wheel, No On/Off button
Problem on iphone 5c 32GB running on iOS 9.3.1.
Bluetooth on/off button simply doesn't exist and does not even allow me to progress as far as to search for a device. No matter how long you leave it, it will not provide the on/off button nor will it pair with anything (I do not believe this is a pairing issue as I can not even get to the stage of turning Bluetooth On because the button is not there and is replaced with spinning).
Tried full factory restore twice, cures it for about 2 days then problem returns.
Another user on Apple Discussions forum has exactly the same problem (see screen shot below) and I am yet to find a solution.
Any ideas?
