Hi guys, I the iPhone SE 64GB. On April 14, the screen started being unresponsive (here's a vid ) for a few minutes, then it would be fine. This has happened a couple of times per day since then. I rebooted it and the touch screen would still be unresponsive a few hours later. Today (April 18), I went to the Apple Store and they gave me a new iPhone. However a couple of hours later, the same problem arose again on the new phone. I'm not exactly sure what's going on - have I been unlucky and received 2 defective phones in a row? Is there something in my apps that's causing this?
