I Phone 5c screen glitches and won't turn back on!
My I Phone 5c (purchased brand new this past March 2014) will randomly glitch and turn off. I'll be in the middle of using it and colors will glitch across the screen, and the screen will slowly fade out and shut off. When I turn it back on, it can take hours for the I Phone 5c to display the lock screen and properly turn on. Even if it does turn back on, as soon as I go to use it again, the process repeats itself! This is very annoying as this was purchased mere months ago brand new and has not suffered any damage what so ever. What should I do? Is this fixable, or do I have to take it into Apple and get a new I Phone 5c? I have insurance and a 1 year warranty on my phone.
iPhone 5c, iOS 7.1.2
