It is expected that HTC's next-generation smartphone, the HTC 10 (aka HTC One M10), would be unveiled simultaneously in New York, London and Taipei April 12, but the company is yet to announce the release date officially. However, its launch is imminent as it's been spotted on the Federal Communications Commission (FCC).

Two models -- 2PS6200 and 2PS6500 -- from HTC, believed to be the upcoming HTC 10, have received approval from the FCC, according to Times News. It went on to say that the telecommunication authority document doesn't have pictures of the devices that would throw some light on whether they are indeed the HTC 10 or some other product. 

According to GFXBench listing (via Winfuture), the HTC 10 will sport a 5.1-inch touchscreen with at least five finger gesture support and 2,560x1,440 pixels, powered by a Qualcomm Snapdragon 820 processor, house an Adreno 530 GPU and run Android 6.0.1 Marshmallow. It also has a 32GB internal memory, a 4GB RAM, a 4GB RAM, a 12MP main camera and a 5MP front-snapper.
