If you have an AT&T Galaxy Note 5 or S6 edge+, getting checking for an OTA update - oh, and make some... time for the download. Around 1400MB of Marshmallow are headed your way, and knowing AT&T's ultra-slow OTA servers, it's going to take you an hour or two to actually get it.
What's packed in this OTA? Hopefully a heaping helping of idle battery life-saving doze mode goodness, along with Marshmallow's granular permissions model, and a whole lot of smaller changes. While many of the UI-facing updates from Android 6.0 won't affect TouchWiz, there are some feature changes lurking that you should be aware of, so check out our feature spotlight series here for a refresher course.
AT&T has taken almost embarrassingly long to release this update. It comes a full three months after Sprint released the same OTA for the Note 5 and S6 edge+, more than three months later than Verizon's Note 5 update (two months for the S6e+), and around two months later than T-Mobile's. AT&T deserves a crown, for it is King Of The Slow Updates.
