AT&T is now pushing out the Lollipop update for the HTC One M8 update, just as they said they would.
Carriers tend to promise things all the time that they don't actually deliver on, but this time AT&T has delivered. AT&T's Mo Versi promised that the Lollipop update would begin rolling out for the HTC One M8 on April 7, and the update is here. The update brings the One M8 back in-line with the One M7, which received its update a week ago already. Included in the update is the new Material Design, revamped notifications as well as a new multitasking UI.
The update is showing on devices, but if you have not received the notification you can check manually for the update. Head into Settings, then "about" and scroll to "software information". If you have already received the update, head into the forums to discuss your thoughts and how it is performing for you.
