Samsung already made it clear that all it’s present flagship devices, including Galaxy S5 and Galaxy Note 4 will get the latest Android Lollipop update. Even in the past Samsung officially tweeted a mockup photo of Note 4 with Android 5.0.
A couple of leaked photos of Galaxy Note 4 running Android Lollipop now confirm that Samsung is almost ready with the porting. The UI has got the Samsung TouchWiz tweaks. There is not much to say at this moment, but we are sure we will get more updates on Android 5.0 update sooner or later.
Samsung has not announced their roadmap of Android Lollipop update for Galaxy smartphones. But we hope this will happen in the early months of next year.
