I've had this annoying issue with my Iphone 5 for quite a while now and I don't know what to do. I've been avoiding going to an apple store as I know it can be quite pricey.
The screen on my phone keeps on freezing if I use it for more than 2 min and the resolution becomes very s*. It automatically locks itself after 1 min and when unlocked the screen looks and works fine for again 2 more min. However, it has periods when it works absolutely fine without freezing even once. Now, I have tried everything, I updated it to the latest version of IOS and also rebooted it.
I would appreciate it if someone could give me any advice. Thank you!
