For awhile now my Cricket Galaxy S3 will keep restarting itself whenever I am at home between 2-7 times a night, or even more while I'm sleep, but while I'm out it works perfectly fine. I don't know what is causing this problem and it gets annoying, very annoying. I called a phone repair place to see what as the matter which they told me it might something wrong with my service provider so I call them and they tell me that it's nothing wrong with the service and I should just have the phone replaced. I'm not willing to buy a new phone since I have a lot on my plate right now. I don't know what it the matter, I thought it was a power button issue since my power button is loose, then someone told me that it may be a swollen battery problem but my battery isn't swollen, so it may be a signal issue since I get a very low signal there anyways? I don't know but this get very annoying every time I am at home and I'm almost getting fed up with it. Does anyone now what the problem is and how to fix it?
