Some versions of the Galaxy Note 5, S6 edge+ are currently receiving performance-improving updates

The software update for the SM-N920C variation of the Note 5 comes with general device performance and security improvements. That's as far as the cryptic changelog goes - there's no elaboration on what the improvements are exactly, but rest assured that we'll get back to you if something noteworthy pops up. 

In the meantime, the SM-N920G flavor of the S Pen-wielding champ scores battery usage optimizations and call quality improvements. The phone has also been enhanced with the general Android security patch for November, and it's worth mentioning that once the new update gets flashed users won't be able to downgrade due to important changes to the security policy. It seems that the changelog for the two variants of the Galaxy S6 edge+ is the same as the one of the SM-N920G variant of the Note 5.

 

We currently have no idea if other Note 5 or S6 edge+ variants are getting updated right now, but be sure that we'll inform you we stumble upon something. In the meantime, we are sure that the majority of Note 5 users are patiently waiting for Samsung to unleash Android 6.0 Marshmallow for the phablet, and if some recent speculations are to be believed, this will happen sometime this month. Those sporting an S6 edge+ will probably have to wait until January 2016.

In case you don't receive a notification for an available update on your device, you can check manually by heading to "Settings", scrolling all the way down to "About device", going inside the "Software update" menu, and tapping on "Update now".
