Re: hanging problems
Welcome to Android Central! Try booting into Recovery and wiping the system cache partition, which won't erase any personal data. Follow these steps, but instead of selecting Wipe Data/Factory Reset, make sure to select Wipe Cache Partition, then Reboot System Now.
If that doesn't help, try also unmounting the SD card (in Settings>Storage), removing it, and rebooting. A corrupt SD card can cause various issues.
