Android M 6.0 Marshmallow Update Release Date For HTC One M9, M8, Desire series on Sprint, AT&T, US Cellular, Verizon, and T-Mobile

HTC is releasing their latest flagship smartphone to the public this week with the HTC 10, and it will have Android 6.0 (also known as Android M or Marshmallow) right out of the packaging.  This leaves users of the older devices such as the HTC One M9 and One M8, wondering if HTC has completely upgraded all of these devices with Android M as well.  The answer is sadly no, and here is the latest news about Android M 6.0 Marshmallow Release Date for HTC One M9, the One M8, and the Desire series on Sprint, AT&T, US Cellular, Verizon, and T-Mobile.

We have been reporting for the past few weeks that the HTC flagships of the One M9 and the One M8 were essentially "taken care of" as far as the Android upgrade is concerned.  For the most part, these two flagship phones, one from last year and one from the year before, have been updated on all the key carriers except for AT&T. 

The International Business Times reports that the Android 6.0 update for both the One M9 and One M8 has been delayed under AT&T further.  Fortunately, the spokesperson for Android on HTC, the one and only Mo Versi, has stated some information about it.  

Versi has become pretty famous for delivering updates about Android upgrades on HTC via Twitter, and a tweet at the end of last month (last week) reveals "HTC One M8 & M9 AT&T owners - there's been a slight delay on M OS. We're in lab but looking at approval within the next couple weeks". 

Also, a lot of the news about the release date for HTC devices has mostly focused on the flagship phones, when there is a whole list of devices that aren't getting a lot of press, but are confirmed to receive the Android M upgrade such as:

  • HTC One M9+
  • HTC One E9+
  • HTC One ME
  • HTC One E8
  • HTC One M8 EYE
  • HTC Butterfly 3
  • HTC Desire 826
  • HTC Desire 820
  • HTC Desire 816

Fortunately, there is some news for users of those HTC devices listed above.  A report from Android Pit reveals that in mid-March, HTC began rolling the Android M upgrade to the HTC One E8 and the M8 EYE.  This appears only to be available for users in China, but a European release is quite imminent. 

So if you have a recent HTC device, it is possible that it has access to Marshmallow already, especially if you have a flagship.  Just go to "Settings" and "System Update" to see if you can download the Over the Air (OTA) upgrade now.  It is possible that the upgrade could be available on one carrier for the same phone and yet not on another, which has become a pattern for Android rollouts.
