So I was just browsing my phone like usual. not even in an app. All of a sudden my phone goes to the blue screen I've read so much about and then the apple logo popped up. thought it would be fine. but it just kept going blue screen to logo on repeat. I got it to stop by doing the lock/home reboot but then when it came back on I got vertical lines and the screen went all wonky like you would see with water damage but the thing is, It's never touched water and I know it has something to do with the weird reboot. I quick rebooted it again and its better but not the screen is shaky in the corners. Any ideas as to what it is or what to do?
