I have a iphone 5c. I had pandora playing. i locked it and then a few minutes later i unlock it to check my text messages and all of the sudden it freezes when i click on my messages. i then lock it and after that the screen wouldn't unlock and screen stayed black. pandora was still playing and i can lower the volume of the music. I can also hear when i would plug my charge to phone. Was told it was just replacing the screen. I would try the power and home buttons to reset it but i have no home button. my screen is also cracked but not really bad. any input would be appreciated before i spend money on a new screen
