Re: 4.3 Update
AT&T is not going to release a 4.3 update for the Active. They couldn't get it stable. Instead, they said they will be releasing KitKat 4.4.2 in the 1st quarter of 2014. But to be honest, I wouldn't hold my breathe. I am realizing my Christmas present to myself is turning out to be a depressing dud.
Edited....
Oh yes I agree it is still a very good device. I have it rooted and can remove all the bloat ware and use all my apps that I like to use and I have WiFi hot spot enabled for it on StraightTalk with LTE enabled on my sim, so I am not that disappointed. I am just a tweak-er/tinkerer and don't like the carriers telling me what I can do with my expensive phone that I paid full retail for. That is my biggest complaint. Otherwise, I do love the phone.
I just got use to the 4.3 rom on my skyrocket and love the 4.3 rom experience. I am currently messing around with SafeStrap and 4.3 roms for the regular s4 . I am sure AT&T will release the KitKat update (most likely at the later end of quarter 1 of 2014), but they should at least update this phone at least once with a stable rom beyond 4.2.2. IMO
