The much-rumored HTC One M9 is now the star of a newly-leaked video, showing the handset's design and software features with Sense 7.0 UI.

The next HTC One, as the company has recently called it, will me making its official debut in just a few short days, arriving on March 1 at the Mobile World Congress (MWC) 2015.

As always before big product launches, the rumor mill is going into overdrive and all sorts of rumors, reports, leaked images and videos make their way online. Things are already heating up and excitement is growing, and the next-generation HTC One M9 now stars in a new leak that seems to be a promotional trailer.

If this video turns out to be accurate and shows the real deal, the HTC One M9 will sport the same design language that has received such high praise so far, and boast some neat software features that would improve the overall experience. The trailer doesn't offer many details regarding the smartphone's exact specifications, but does note that it will allow for "better selfies in low-light" and boast HTC BoomSound with Dolby Audio Surround for a high-quality audio experience. Some neat camera features are apparently in the cards as well.

Rumors so far have indicated that it will have a 5-inch display with either a full HD resolution or a QHD one, pack a 64-bit Qualcomm Snapdragon 810 processor under the hood, 3GB of RAM, a 20-megapixel rear camera, and an UltraPixel front shooter (some reports also mentioned a 13-megapixel front camera). In terms of software, the next-generation HTC One M9 will most likely launch with the latest Android 5.0 Lollipop on board out of the box, with HTC Sense 7.0 on top, as shown in this video.

The video below comes from Dutch website TechTastic, which credits trusted tipster Upleaks. As always with leaks, however, keep in mind that it all remains in the rumor state until the official unveiling. With HTC's March 1 big event just around the corner, we'll soon learn all there is to know about the new HTC One M9, so stay tuned for more information as soon as it becomes available. Take everything with a grain of salt in the meantime, including the leaked teaser video below.
