Wow you've done a ton of work already ctubby. I'm really surprised after all this it's still giving you trouble. Which model Samsung do you have? Have you also tried using the phone in Safe mode to see if the same thing happens? After you reset the phone, did you test out the SD card first before you put all your data back on the phone?
Hey there! I agree - you've done an impressive amount of troubleshooting solo. Were you able to test out the additional suggestions Mike offered? How is everything going?
