HTC isn't exactly known for speedy updates, but the company has been known to push them quickly in some cases. This is definitely not one of those cases, but it would seem to be more Verizon's fault than HTC's. Slightly over a year since the release of Android 7.0, the One M9 on Verizon is finally getting a Nougat update.
The Verizon variant is the last One M9 model to receive Android 7.0 Nougat, at least in the US. T-Mobile was the first in March, Sprint pushed the update in April, and AT&T released it in May. Verizon's update has a build number of 4.49.605.11, and includes the August 1 security patch level. It has all of the goodness that Android Nougat has to offer, including split-screen mode, enhanced Doze, and more.
You can find more information about the update at the source link below. Verizon One M9 owners should see an update notification soon.
