I have restored my ipad to factory default 3 times in3 months but it still keeps turning off
I have restored my ipad to factory default 3 times in 3 months but it keeps going blank or freezing with the apple logo appearing on the screen but not much else working, I have tried many times pressing the on/off button at the same time as the home button for 15 seconds which brings it back to life but not for very long. I can't play any games on it, it freezes after a few minutes. The ipad is about 3 & a half years old, is this the length of life I can expect from it ?
iPad, iOS 9.3.1
