Leaked information revealed a list of 15 HTC smartphones set to receive Android 6.0 Marshmallow and Sense 7.0 update. However, popular HTC One M7 is not included among the preliminary list of devices to get the update.

Tech Times reported that known tipster @LlabTooFer posted a list of HTC smartphones to receive Android Marshmallow and Sense 7 update, though HTC has not made an official announcement yet. The list includes devices in the Desire and Butterfly lines, as well as the One M9 models.

TechnoBuffalo listed the HTC phones receiving the update as per tipster's information. The HTC devices receiving Android 6.0 and Sense 7.0 are the following: One M9, One M9+, One ME, One E9, One E9+, One M8, One M8s, One M8 EYE, One E8, Desire EYE, Desire 816, Desire 820, Desire 826, Butterfly 2 and Butterfly 3.

According to Tech Gadget Central, the list does not include one of HTC's most popular and successful devices, the HTC One M7. It might not have been included because HTC wants to promote its newer models. On the other hand, the HTC One M8 and its variants will likely get the update, but the only officially confirmed devices are those belonging to the HTC One M9 line-up. Tipster @LlabTooFer said that mid-range devices could also receive the Android Marshmallow and Sense 7 update.

@LlabTooFer said that the above list is preliminary and subject to change as HTC rolls out Marshmallow to its devices. The tipster added that devices which have limited internal storage like Desire 816 might be removed from the list. HTC is expected to make an official announcement sometime soon following the unveiling of Android M and new Nexus devices on September 29.

HTC will likely roll out the Android 6.0 Marshmallow and Sense 7.0 update to its latest flagships first in November, then trickle it down to older models. It takes around three months for HTC to release updates to smoothly incorporate its own features into the Android OS and make it compatible with HTC devices.
