I've had the Samsung Galaxy tab S 8.4 T705 LTE for a month now. Upgraded to lollipop some daye ago. The problems: 1) Battery life lasts for 3-4 hours with little use, whereas before with kitkat battery life lasted from morning to night which was very impressing. 2) the new interface/UI in all menus, settings, contacts and so forth, are pure white background AND everything has become smaller! This is not eyefriendly. 3) Unfortunately, I don't have the brains to downgrade from lollipop to kitkat.
