Moto G4 Plus here...other day I just had the phone on my lap, all of a sudden it started flashing between a gray screen and my regular home screen. Wouldn't stop, I decided to restart the phone. I did that and all of a sudden a bunch of my apps were missing. My SD card was not working, took it out, put it back in, nothing. Tried to reinstall, was received with error 963 for all apps. Tried a new SD card, still made no difference. Cleared out space on my actual phone, still nothing. Tried using my camera, and error screens pop up. Not sure what to do?? Please help!
