I just bought my SGS3 and really like it. I am on AT&T's network and am unrooted. However the one thing that annoys me is that when sending multiple text messages, you must wait for the first message to be sent before you start typing the second message. If you start typing the second message BEFORE the initial message has been sent, the phone starts lagging and the letters you type show up on about a 5 second delay. I also noticed that it a lot of processes are running (by alot I mean about 1.1GB of ram used) the messaging lags in a similar manner. Also, the predictive text does not seem to be on par with other devices, so if anyone has a good suggestion for a new keyboard that would be great. Please help out! I Have tried disabling power saving mode already without success.
