I have had my iPhone 4 for a little over 2 years. I upgraded to the 5. I cracked the screen to the 5 and am back to the 4. Problem is, it turns itself off. I cant move the phone very much or plug it in without turning itself back off. I have to try multiple times and keep it very still before it will actually power back on. Its done this to an extent but never this bad. Ive updated my software and whatnot so it isnt that. Also, holding down the home button and lock button doesnt help. Im using this phone temperarely and its really annoying. Is there any thing I can do to fix or at least help this problem? Its not full storage either I already cleared it. Helpppppppp!
