So after the Samsung software update 3.0.31 build date Feb.14th 2013 I have noticed that texts now lag when backing out of the screen and the keyboard is open. I confirmed it with my brother in laws S3 which was not updated and did not have the issue until he fell asleep and the phone updated automatically which he did not want and now he has my issue also. Also noticed missing icons on home screen on battery changes and reboots and lag in between switching back and fourth to different programs/screens. I confirmed the issues at a Sprint store the tech agreed. Factory wipe fixed a few issues but the lagging text it did not and so far no missing icons on reboots. Thanks for messing up my S3 Sprint and Samsung way to go on this update. How is yours acting after this update? This is for Sprint only.
