I noticed that my S3 works really well when I am home connecting to WiFi. I also noticed with I have LTE. What I meant by that is: any kind of operation is simply smooth as iPhone UI and even better. It is simply very snappy, very responsive. When I am on 4G, I noticed some operations are a little jerky. I am not talking about the S3 is waiting for data or with the spinning circle thingy, those I understand. I am wondering if anyone notice it? I thought, it max out RAM, I cleared it. it's not much diff when on lower bandwidth.
