I have a little problem. I like to hook up my phone to my car stereo and play some music with YouTube when I'm in my way to work. The Problem Is that after about 5 min the screen freezes while the music still plays in the background. I'm have to take out the battery to get the phone to work again. It's very annoying. It only happens when in in the car. Just to be clear I'm not watching and play with the phone while i drive. It only plays music. Is it a software issue, hardware, sim card? Any idea?
