GS3 vs GS4 screen vs screen there shouldn't be a big reason to jump for current GS3 users, tech heads like us will do it because we know what we are getting. But if you are using a 2 year old phone like the GS2, its a big jump up.
The GS3 is still a very nice phone. If you have your upgrade and want to stick with your current carrier sure. If your buying it at retail price, I don't see the point. Wait for the next Galaxy phone.
The GS3 is a great phone and honestly there is no "big" reason to upgrade unless you are a tech/device ***** like most of us. I chose to upgrade because the iP5 I had I could not live with and I enjoyed my GS3 a lot but really wanted the GS4 for the better screen, processor, and overall features plus a more current OS.
Yea probably shouldnt upgrade. When i had the s2 at the time i felt there was no big reason to upgrade to the s3 beside bigger screen. So now im here about to get the s4.
