Tip: Random reboot from bad battery connection fix

[maxburn]

My international N7100 has been rebooting on me a lot lately. At first I thought it was the power button hitting something in my pocket but it turned out to be a loose battery. The battery on my phone has a small amount of movement in the battery chamber and was apparently not making a good connection. I shimmed the side opposite the contacts to push the battery into the contacts and the phone hasn't rebooted sense. It took about five or six layers of regular copy paper to take up the spare space, you will have to cut some slivers of paper to size.

Just something to check into if your phone is being less than reliable.
