Okay, my S3 is no longer my daily driver. However I use it when in the field birding for my ID apps. I'd rather risk it than my S7 going in and out of my pocket frequently. Plus i have the add on to attach it to my spotting scope for pics. yesterday I turned it on and it booted into safe mode. It gave me the option to turn safe mode off, I did and it rebooted itself right back into safe mode. Turning it off all together and restarting gave the same results. It took a battery pull to sort things out. Happened again this morning. any thoughts other than a factory reset?
