Apps on SD showing as not installed, phone is constantly rebooting I've had the apps on SD card not showing issue a few times, but in the last few days anytime I use the stock camera app no apps show on the screen and when rebooting I get "no service", "service disabled" and the apps on the SD card show as not installed. My phone is now rebooting and in a reboot loop until I pull the battery.

Phone LS470 running 4.4.2
Boot into recovery and clear Cache and Dalvik-Cache, if you are rooted. If not then search about how you can boot into stock recovery and then clear Cache and Dalvik-Cache.
