Hello All, I am a new member. My name is Steve Bowers. I have a Galaxy S3. I have a few issues that I need some help on. 1 - I purchased a 32GB chip for my phone. I checked several other blogs to make sure I bought the proper kind. However, a few days ago I got a message that the chip was damaged and I had to re-format it. 2- When I plug in the phone to my PC, it tells me that it is connected as a USB device, but I never see it when I look at the devices attached to my PC. 3 - Every now and then the phone just reboots itself for no reason. I am not sure why. It did recently update to 4.1.2. When it reboots my wifi does not connect.
