My GS4 surprised me with an unexpected update at 2:15AM Monday morning. It circumvented my plan to do a FDR *before* the update. It had d/l the update around noon Sunday and I kept hitting the remind me later button on the nag screen until I could find time to prep for the update. Oh well, it just self-approved the update in the middle of the night. Not too pleased with that.
As it is, I've seen no issues after the update although I suspect my battery usage is higher than before. Ergo, I just wiped the cache partition and will watch to see if that improves anything.
Two things I don't care for with KK 4.4.2:
1) all white notification icons (I miss the green/red arrows for wifi activity)
2) KK moved the clear button in the notification shade to on top of all notifications, not just the temporary notifications where it was prior to the update.
Both are minor nits in the scheme of things. I'll monitor the update for other changes I haven't caught yet. But otherwise, I see no operational difference (including how I use my SD card and transfer files via WiFi to my PC) with KK vs JB.
