My note 3 reboots several times a week since the upgrade to kit-kat.
I tried searching around to see if anyone else had posted about this.. but I didn't really find anything.
I'm sure you all have had it at least once (not just kit-kat) - but its your classic, you hear the vibrate the screen turns off and then its booting itself up.
This is a stock Note 3.
I'm assuming if I don't hear any feed back on here I will just get it swapped - kind of annoying.
