My Galaxy 4 has been randomly reseting or shutting down completely nearly 3-4 times every hour (for a couple of days) while trying to instal new software (notification would pop up and then go away). I eventually downloaded the software ware (settings/More/About device/Software update). Since succesfully updating the software my phone cuts off only 3-4 times a day.
Thanks to social media, this isn't a problem that i'm experiencing alone. What is really going on TMobile?
