Earlier this week, we heard rumours of Google reportedly signing a deal with its old partner HTC that made the company's first vanilla Android phone Nexus One (aka HTC Passion) in 2010.

Now popular Twitter spy LlabTooFeR, citing reliable sources, has revealed the codenames of the rumoured HTC Nexus smartphones. The 5.0-inch and 5.5-inch screen based devices have been assigned as T50 and T55 respectively. Other key details such as display resolution, RAM, storage, camera and battery capacity are yet to be ascertained.

As of now, neither Google nor HTC has responded to the reports, but the good track record of LlabTooFeR's previous predictions make us believe that this might just be the real deal.

We expect to get a clearer picture during the upcoming Google I/O 2016 developer's conclave, where the company's top executives are bound to announce what the American firm has in store for fans this year.

For the uninitiated, after Nexus One series, Google worked with HTC to launch another Nexus device in 2014 -- a tablet -- but it failed to elicit good response in the market.

That said, if HTC is indeed making Nexus series phone this year, it will certainly help the Taiwanese firm to turn things around.

Unlike tablets, smartphones have much more traction across all markets -- developed (America and Europe) and emerging nations such as China, India and few other select regions Asia and Africa.

Many believe that the Nexus series will aide HTC in arresting the decline in smartphone sales. In 2015, HTC One M9 series failed to impress critics and fans alike as it featured only incremental hardware rather than any stand-out feature to boast of. This year, things may change for good for HTC.

Google had also collaborated with LG and Huawei to make Nexus 5X and Nexus 6P respectively in 2015.
