Samsung Galaxy Note
The original Samsung Galaxy Note is in the same boat. It remains on an ancient version of Jelly Bean with no hope in sight. An upgrade to Android 4.2 Jelly Bean or Android 4.3 would be a miracle at this point so Android 4.4 KitKat is out of the question.
A leaked document indicates that Samsung isn't even putting the Galaxy Note and Galaxy S2 up for consideration for Android 4.4 KitKat so those who have held onto this relic need to stop holding on to hope.
