A video of that new firmware has surfaced online, giving us a look at new icons, a new Air Command menu, and the screen-off memo feature from the Samsung Galaxy Note 5. Everything seems to be working as if Samsung intended for it to work, so suspicions that the new features might be due to app hackery might be unwarranted.
Beyond visible improvements, there’s said to be a significant improvement in performance, something we’re really glad to hear. Unfortunately we still don’t know whether the update this guy received is final or whether it’s a test build, but with Samsung not looking to bring Marshmallow to the Note 4 until 2016we’re going to leave open the possibility that there’s still more to come.
