Update to UI 7 is horrible. The battery is taking a pounding. Hate the bubble for battery percentage. Widgets do not fit properly, it cuts of notifications making it a pain to scroll through. The increase in brightness using the slider is clunky and not precise anymore. Having to scroll through the panel is not great. The panel has shrunk. The font has changed to black and bold. It's no longer the sharp look that Samsung is known for. It resembles Apple. If I wanted an I phone/tablet I would buy one. It would have been great to have the option to revert back to old look. I hate it.
