Marshmallow is making its way to Galaxy Note 4 and Note Edge owners in the US. If you're on T-Mobile, you're next on the list. The Un-carrier is now sending out OTA updates to people on its network.
This update bumps both devices up from an aging version of Lollipop. Note 4 owners should be on the lookout for software versions N910TUVU2DPE3 or N910T3UVU1DPE3. The former comes with a Google Voice fix, while the latter includes an anti-theft update of some kind.
The Note Edge is going up to software version N915TUVU2CPE3. For this device, the changelog only mentions Marshmallow.
