HTC's M7 is one of the many smartphones that have been the subject of big rumors over the month with each day passing. While some reports have stated about the device's expected features, others have discussed about the probable carriers and release dates. However, here's a list of everything that is known about the M7.

It is massively believed that the HTC-made M7 is expected to make an appearance at HTC's Feb. 19 press event. The news of the February press event emerged last month when sites all around the Internet began speculating that the M7 could be revealed at the event.

Later it was known that the company would be holding a dual press event on both sides of the Atlantic - London and New York, to be precise, although it is still not clear if the company will eventually make the device official.

Moreover, the device was back again in contention earlier this month when HTC CEO Peter Chou was heard chanting its name at a recent company event. The information was revealed from captured screenshots from a TV news broadcast of the event where Chou was allegedly seen using the white M7 to take a few shots of the crowd. However, there was no real close up shot of the device Chou was using and so the prospects of M7 still hang in a balance. Here's a video capture of the event:

The M7, only recently, was also spotted in the retail computer systems at Carphone Warehouse. This also served as further confirmation about the name of the device. "The listing from Carphone Warehouse's internal system shows the HTC M7 listed in two colors - black and silver - as well as accessories, with HTC M7 hardcover and HTC M7 screen protectors included," the Pocket-lint report said.

"We're led to believe that Carphone Warehouse never lists devices under a codename, so that may well confirm that the final name will in fact be HTC M7."

The M7's camera has also come into a lot of speculations over the months, and it is being said that the device's camera could feature some groundbreaking tech. Pocket-lint states that the company is currently set to use a brand new camera sensor which the company calls Ultrapixels.

Although reports say that the smartphone will use a 13-megapixel sensor, internal sources say that the camera "will instead be made up of three 4.3-megapixel sensor layers combined to give a resulting single image. Three lots of 4.3 may add up to around 13-megapixels, but images from HTC's latest won't be output at that larger size."

Lastly, a new rumor says that all the major U.S.-based carriers - AT&T, Verizon, T-Mobile and Sprint - are interested in the M7, and Verizon will probably be the last carrier among to them to launch the device.
