I upgraded my Galaxy III on 7/20/14 and have had many failures of the phone since then. I generally charge it every night and 3 mornings last week when I went to check my phone it was blank....like it was turned off. None of the buttons responded. I finally took the battery out and then it powered up letting me know that it was fully charged, so I know that it was not a discharged battery. It has also distorted the wallpaper picture on the lock screen. The camera failed 3 times last Saturday. I had to reboot to get the camera to work.
In the settings there is a factory data reset. What do I need to do to save all my info before I do something like that. Will doing that put the original software back on and thus solving this problem? I had no problems with my phone before the update.
thanks for any help on this...
