I upgraded my Note 3 to 4.4.4 last night using Kies. Everything seems to be working well, battery life may be a little bit better. Are there new features with 4.4.4? I can't see anything new.
I have had 4.4.4 on my work phone (Droid Maxx Verizon) for a couple months now and the only thing I see different than my note 3 is some of the icons have changed. The radio's on both phones and the signal strength are the same anywhere I have traveled.
