Touchscreen randomly becomes unresponsive
bought an iPhone 6 Plus on eBay. It's in perfect condition and I think I got a bargain. It has an issue though, which was why it was sold as not working: the touchscreen randomly becomes unresponsive and the phone needs a reset to make it start working again.
It seems to do it particularly if left untouched for a while.
I did a restore in DFU mode and it's still doing it.
It's 16 months old so out of warranty with Apple.
I booked an appointment with a genius tomorrow, but I believe that they won't fix that for free, even if I read on their forum lots of people complain about this issue especially after upgrading to iOS 9.
Also, worth mentioning that I checked the serial number of this iPhone and it qualifies for the Apple free iSight camera replacement program for the Iphone 6 Plus (rear camera producing blurry images).
Does it sound like a software issue or a hardware one? Thanks in advance for any replies.
Is this a good question?
