I updated to 4.3 about 2 months ago and it keeps crashing and basically has ruined my phone, I don't want to factory reset and I know 4.4 is out in the UK as a few of my mates have it. Now I can't seem to get 4.4 as it says I'm already on the latest firmware (4.3) which is a load of bull. Tried it via Kies and get the same (or similar) message. Why can't I get 4.4? And will 4.4 fix the crashing/freezing problem? It was perfect before I updated. Thanks!
