First of all, we say that the software is now marked N910CXXU1BOC3 and continue to Android 5.0.1 Lollipop. Changes are few, but the most important is the return of the "Mute", which somehow disappeared in Lollipop. I also noticed that the interrupt function is now called Do Not Disturb and is used to mute all calls, notifications and alarms outside the defined exceptions. Certainly improved liquidity and contacts startup speed, switch between the dialer and contacts or gallery, which now opens much faster. I can also confirm that other users who also noticed that finally Lollipopie run applications that previously throwing error. I also have the impression that the light beam has undergone a facelift notifications. You do not have this feeling that changed the brightness icon on the toolbar? The battery is difficult to say anything, but I sincerely hope that there is no longer a delay after the call is answered, and finally the GPS to work properly (does not sever the connection).
