As soon as I put my code in to use my cell, It is showing launcher has stopped. I can not do anything or select
Power it down and put it into safe mode. Power it down.Power it back up.Hold both the volume buttons until it boots. Do not let go. Uninstall any luancher app you may have. If you can, install a different one from the store. If all else fails, then reset the phone. Go back into safe mode, go to settings, then Backup and reset, and reset. Hope this helps!
