HTC is seemingly building two Nexus devices in association with Google which will run the latest Android N operating system, which will be released for the public in third quarter of 2016. The devices carry the model numbers M1 and S1 internally.

The latest disclosure was made by Twitter leakstar, Evan Blass, who runs the Twitter handle @evleaks. The internal model numbers are said to be for the devices, which Google is currently using for Marlin and Sailfish. Google normally keeps names of its Nexus models after aquatic life, for instance 5X and 6P were called bullhead and angler, Nexus 6 was Shamu and Nexus 5 was hammerhead.

The details provide by @evleaks were further corroborated by Android Police, who have obtained the AOSP Gerrtit – a code review tool – on 30 March having references to Marlin. The person referencing Marlin is a senior Qualcomm engineer. Qualcomm works closely with all its device's partners, which hints the chip maker might have knowledge about the Nexus device, provided it would incorporate a Qualcomm processor.

The M1 and S1 are the same devices that were earlier rumoured as T50 and T55. The names referred to the screen size of the devices, but the names were dropped later on. Apart from the names, the revelation by Blass did not provide further detail about the technical specification nor about the launch of the device.

Meanwhile, Google recently announced the scheduled of its annual I/O developer conference to be held at the end of May. Expect announcements about a number of products ranging from VR, self driving cars to Android Wear at the developer conference this year.
