A "preliminary" list of HTC devices is shared by an inside source with knowledge of the company's plans to update to Android Marshmallow. The list includes devices that will have updates to Android Marshmallow and HTC's Sense version 7. This includes the HTC One M9 and HTC One M8, of course, but does not include the HTC One M7. Also included are a wide variety of "M" devices, "E" devices, and Butterfly 2 and 3. This list, being preliminary, may be a bit deceiving for some devices that do not have enough base storage for Marshmallow in the first place.
