I got 2 major problems when I take out the battery. The first time I took it out to put my 16G micro SD in, it was fine. When I replaced it with the 64G that came in from Amazon, the phone kept turning itself off after a few minutes of sleeping.
I had to reset the phone and everything was fine again. The third time was when I decided to register my phone at Samsung's website. I needed to take off the battery to see the info on the phone. When I was done and put the battery back in, the phone went into a endless reboot loop.
I found this site the helped me stop the loop.
