Verizon branded HTC One (M8) receives Android 5.0 update
The HTC One (M8) Verizon update brings the Lock Screen notifications, "Recent Apps" menu, Project Volta, 64-bit ART compiler and the Lollipop Android 5.0 Material Design to name a few. While Verizon subscribers might feel that they have waited the longest for this update, AT&T account holders with the HTC One (M8) received Android 4.4.4 on January 19th which means it could be some time before this group gets Lollipopped.
Those Verizon subscribers with the HTC One (M8) should make sure that they are on a Wi-Fi connection when downloading and installing the update as it is quite hefty. You should also make sure that your battery is charged to at least 50%. Keep in mind that the update is being sent out on a staggered basis. If you don't get it today, you might tomorrow. And if you don't get it tomorrow, there is no need to look for a tall building to launch yourself from. The update will eventually arrive. You can try to coax it out manually by going to Settings > Software Update > Check New.
