Nearly a year after Android 6.0 Marshmallow first debuted on the Nexus 5X and 6P, the AT&T models of the Samsung Galaxy Note 4 and Note Edge are finally receiving an OTA for 6.0.1. Samsung has never been reputable for fast updates, and neither has AT&T. This incredibly late update is what happens when you mash the two together.
This update is beginning today for both the Note 4 and the oddball Note Edge. For the Note 4, the new baseband version is N910AUCU2EPH5, and the Note Edge's is N915AUCU2DPH5. The downloads, which weigh in at a hefty 1.3GB for both devices, include Android 6.0.1 Marshmallow with the August 1, 2016 security patch, Video Calling, Advanced Messaging, and Wi-Fi Calling. To update, your phone needs to be connected to Wi-Fi and on OI6, OI7, or OI9 firmware.
