HTC VP Mo Versi took to Twitter this morning to inform owners of the company's plans for the One M9's Marshmallow update, as well as the all-new A9's incoming bump to Android 6.0.1 (it ships with 6.0). Specifically, both devices can expect their respective software upgrades some time this month if all goes according to plan.

Lots of questions on this, so quick update: M9 unlocked Marshmallow OS update and A9 6.0.1 (with updated emoji) is on target for this month.

The unlocked One M8 is already getting Marshmallow, so while it is a bit odd that the newer M9 will be getting it later, at least it won't be that much later.
