Galaxy s4 shutting off randomly

[Brittany Moss]

I have had my s4 for about 8 months and for no reason at all it would randomly restart itself and then I did a system update and now it will randomly shut off and not restart itself. Im thinking it is probably a battery problem but im not completely sure. Does anyone know what other problems it could be? I checked the battery for swelling and it isnt swollen. Also does anyone know if tmobile will replace the battery for free?? Thanks!

Welcome to Android Central! Try booting into Recovery Mode and clearing the system cache partition: Reset: Samsung Galaxy S 4 | T-Mobile Support

If that doesn't help, see what happens if you unmount your SD card (Settings>Storage), remove it, and reboot. A corrupt SD card can cause problems.

It's always helpful to try a new battery. If you find out the battery wasn't the problem, at least you now have a backup battery.
