OTA, havent try factory reset..
4.3 isn't that bad but there are a few problems occurred but they happened occasionally that are probably caused by 4.3 :
1; phone auto reboot after call ended
2; phone auto reboot after launched camera
3; phone battery drain too fast on mobile data (didn't test on wifi)
4; keyboard is less responsive, eg : when you type "LOWYAT" phone can only sense "LWYT" ( Will be fixed by itself after typing for a while )
5; Camera could not take photo/focus (totally no respond) but only can launch the app, 3 function key still responding. (Can only be fixed after reboot)
these problems had no appearance before the 4.3
will wait for any fix from Google but I'm losing patience
i have none of these issues. the only problem after 4.3 update is wifi sometimes stuck, can't switch it off and even when it's on, can't get any data via wifi, need to restart, but this problem rarely happens.
biggest improvement is the photosphere. can most of the time join lines that are close, previously can't take photosphere of my room, now can do it
