ok. updated earlier using kies. im tmobile uk. so far, no problems. videos in the video app are moving as they were before update. waiting for phone to fully charge to test the 100% but mine did go to 99% as soon as you unplugged the charger. my android os is showing 55m 20s and android system is 14m 36s. not sure if these are that high and dont know when they might start to come down. always had samsung chat on.
