Rumors have it that Google and HTC are working on two Nexus 2016 smartphones that are codenamed as Marlin and Sailfish. The appearance of “Marlin” on Google Chromium source site confirms the previous rumors on existence of Marlin Nexus smartphone.

The appearance of Marlin on Google’s source site does not reveal the specifications or features of the purported HTC Nexus smartphone, Mobi Picker reported. The source site also includes codenames like “Angler” and “Bullhead” that respectively belong to Nexus 5X and Nexus 6P smartphones from 2015.

In April, well-known leakster Evan Blass (@evleaks on Twitter) had revealed that HTC is building two Nexus smartphones that are codenamed as Marlin (M1) and Sailfish (S1). Rumors have suggested that one of them will feature 5-inch screen and the other one will house a 5.5-inch display.

According to Android Headlines, fresh speculations indicate that the alleged smartphone will be powered with Snapdragon 821 chipset. The HTC Nexus 2016 smartphones will come preloaded with Android N OS.

Speculations suggest that the Snapdragon 821 chipset is a slight improvement over Snapdragon 820 chipset that powers several 2016 flagship smartphones such as Samsung Galaxy S7, HTC 10, LG G5, Sony Xperia X Performance, and Lenovo Moto Z. The Snapdragon 821 is expected to deliver faster processing speed than Snapdragon 820. The Snapdragon 821 chipset is expected to power other smartphones such as Samsung Galaxy Note 7 (aka Note 6) and a newer variant of Asus ZenFone 3 Deluxe.

In the recent past, rumors had surfaced that an upgraded edition of Nexus 6P would be launched by Huawei this year. The alleged smartphone was spotted on a benchmarking site with Snapdragon 820 chipset and 4 GB of RAM.

The original Nexus 6P features Snapdragon 810 chipset and 3 GB of RAM. Since Google source cite only mentions the codename Marlin but does not reveal its manufacturer, speculations are claiming that it may be the upgraded version of Nexus 6P.
