Perhaps try factory reset ? You done it via OTA / flash it by yourself?

What was the problems you are facing?
4.3 seems good enough, except for the occasional BT power drain and recently high power consumption from Google Track (no idea what triggers it). Nothing a reboot can't fix so far.
So far, 4.3 (stock) is really fast, buttery smooth, even compared to CM10.2 (4.2.2) which stutters even at app drawer, bummer. And of course, the best ROM to date is still 4.1.2, which I have clocked more than 1600 hours of uptime on my GNex.

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
