So I've been experiencing some glitchy behavior whenever I receive a text. When someone texts me (and I think the text has always been an iMessage) my phone's screen will flash for a second, play part of the text sound then go black again. If I hit the power button, it flashes on and off and will play the remaining part of the text sound (usually garbled). I have to hit the power button again to finally bring up the screen. I didn't know if anyone else has experienced this or if it's an isolated incident. I am still under the Apple warranty and could set up a Genius Bar appointment. I just wanted to see what everyone here thought first (since the Apple store is about a 30 minute drive). Thanks for the help!
