AT&T will finally (I mean...finally!) start rolling out Android Marshmallow update to the One M8 and One M9 starting May 12th. After several delays, the update will bring much needed performance and battery-life improvements to both devices with an update to HTC Sense as well.
Mo Versi, VP of Product Management at HTC just tweeted the happy news:
HTC One (M8 & M9) AT&T owners! Thank you for your patience. Marshmallow OS is approved, OTA to start tomorrow!!— Mo Versi (@moversi) May 11, 2016
The update will be rolled out gradually, and don't worry if you don't see the Marshmallow update notification right away. If you still can't wait, you can head over to Settings and check for software updates in About phone. Since I am not using the One M9 anymore I would love to hear about your experience with the new update, do share in the comments section.
