I'm running SS4.9 and only recently have I been experiencing issues with my phone locking up while booting into the OS. Initially I didn't have issues with my phone locking up while booting into SS4.9. It almost seems sort of routine, like the OS gets to a certain point and then either slows down and briefly locks up before getting past the hiccup or permanently locks up. More often than not the brief lock up results in a permanent lock up until I pull the battery. Once the OS fully loads up, everything runs fine including the SD card if I mount it to the computer. Any advice would be greatly appreciated.
