AT&T announced that the latest update update for the HTC One M9 would launch yesterday, but the details have become official only today. The changelog has been posted for the Android 5.1 Lollipop update and you can start pulling it now!
The update really isn’t that big. Android 5.1 comes with some small but nice improvements over the previous software, fixing many of the bugs. It also features better low light camera performance, which is a great reason alone to download it. Otherwise, there isn’t much to mention.
If you want to get the update, head to Settings > About phone and check for software updates. You might get it immediately, or you might have to wait for it to roll out to you. It’s a 914MB download so stay by WiFi for this one. Let us know what you think when you get it!
