Check out the Galaxy Note 4 running Android 5.0 Lollipop on video
Courtesy of SamMobile, the 3 minute-long preview gives us a peek into a world where the Note 4 is making use of the Material Design-ed OS update. That said, if you're familiar with how the aforementioned, TouchWiz-based devices looked like when running Lollipop, then you're unlikely to find any surprises here. Indeed, we again have a Material Design-inspired UI (incomplete, seeing as this is a non-final version of the software), complete with rich, Lollipop-style animated feedback and a revamped notifications area. Like before, it's now clear that Samsung will be adhering to the new design guidelines, so expect bright, solid colors throughout.
As pointed out already, not all Samsung apps have been restyled just yet, though the Dialer, Contacts, and Messaging, among others apps, have gone through a layer of fresh paint. You can see those in action in the video below.
The Android 5.0 Lollipop update for the Note 4 remains shrouded in some mystery, and we're still short an ETA. That said, the consensus right now seems to be that the Samsung phablet will get the new firmware either at very end of this year, or in the first few weeks of the next one. We hope that we have more than speculation to go on soon and will update you folks once we do.
