★Like the video? Subscribe! br I recently did a fresh install of CyanogenMod 10.1 on my Galaxy S3. It was experiencing lag and battery issues and I was actually contemplating putting the factory ROM on that comes when you buy the GS3. Well, i twas actually harder to find the factory software than it was to find the latest build of CyanogenMod so I just decided to do a clean install of it on the phone.br br I'm happy to say that I have had almost zero issues with it so far. The only time I had a problem was when it froze one time when I was trying to answer a phone call. Together than that it has given me no problems and the phone is once again fast and has great battery life.br br Here's the CyanogenMod 10.1 download page for the AT&T Galaxy S3.
