I have just installed Jelly Bean 4.3 in my Galaxy S3 thru OTA. But its a bit lagy. People are suggesting to do a factory reset after installing 4.3 so that it will not be lagy.
I have many games, apps installed and I need the games' saved files and data to be backed up and restored after factory reset. Please let me know a way for this. My phone is not rooted so that I will not be able to use some backup apps which requires root for backing up games data files. I have some 100+ downloaded apps and games which I need to backup and restore them after factory reset. Help me!
Thanks in advance.
