A recent beta of Lollipop gives Galaxy Note 3 users the opportunity to play with the newest android update. It is likely that Samsung will not be updating the Note 3 to Android 5.0 any time soon and the most recent official update from Samsung for the Note 3 is 4.4.4 KitKat, but thanks to a post on XDA Developers, users can update to the newest Lollipop beta right away.
While most features seem to be working from the images on the source Vietnamese site, and the build is stated as being an official beta from Samsung, the fact that this is a leak is a cause for concern, and it may not be stable enough to use as a daily driver as of yet.
Unfortunately for the majority of Note 3 users, the beta is only compatible with the N900 international variant of the device. If you would like more info, or wish to download the ROM, visit the XDA Developers post.
