Backing up my S3

[d_schaefer]

My S3 has gotten slower and slower, starting with the last software update. I've wanted to factory reset the phone to see if it helps but I don't want to until I've got a good back up.

With other android phones, I've plugged them into my laptop, browsed the file system via Windows and copied the entire directory structure over. With the S3, however, I can't do so. I can see the folders, but when trying to copy them my PC gives a message that it's trying to calculate the time it will take to copy and Windows Explorer locks up. I have to force close Windows Explorer.

How do I back up my S3?

Put Samsung Kies on your phone and laptop and it should work. Kies

I'm not having any luck with Kies. After choosing to back up all items, I let the first attempt run for 3 hours and it was stalled on "S Planner" for most of that time. The second time I let it run for almost an hour and it was stalled don "photos". Now it won't connect to my phone to try again.

On another forum, someone suggested Windows software called MoboRobo, which I'm going to try, but I'm thinking there's something wrong with my phone that's preventing access for backup.

You must use the cable that came with the phone.
