HTC One M9

Following yesterday's announcement, HTC has started rolling out the Android 5.1 Lollipop update — coming in at 831.88MB — to the One M9 in Europe, the Middle East, and Africa (EMEA).

In addition to all the new features in Android 5.1, the update improves the amount of time taken to charge the battery. HTC is rolling out the update in stages, so if you don't see the OTA just yet, hold tight. It's coming.
