A new leaked video shows detailed specifications and the exterior design of the all-new HTC One with larger screen, Sense 6, dual camera and a lot more.

HTC is expected to launch the All New HTC One March 25. The company plans to reveal some hints of the upcoming flagship phone prior to the release to build consumer hype.  HTC's Translation video #1: BoomSound from last week gave away a few details about the new phone.

Another leaked video, not from HTC, doing the rounds has put a bit of a spanner in the company's plans. A leaked 12-minute video by a YouTube user "GadgetReviews" shows off the design and the software of  AT&T HTC M8. The video no longer appears on the video streaming site and the leaker revealed on Twitter that the HTC phone in the video is not real. The video has been on and off the site from the time it went viral but currently it appears under a different account by Nicky Perdaen. The specifications shown in the video resemble the ones previously reported in several rumors and press image leaks, adding more value to the video. The comparison of the all-new HTC One with the original HTC One shows a clear difference and gives it an authentic touch.

As per the video the hardware design is not much different from that shown in previously leaked photos. It shows a larger display, dual camera, dual LED flash and front-facing speakers. Additionally, the video shows the sensors have been moved toward the right side, next to the front camera.

For the software part, the video shows HTC One successor carrying the latest Sense 6 custom UI, along with a revamped Blinkfeed that shows up from the left side of the screen. This is similar to the My Magazine feature on Galaxy Note 3. The video also shows on-screen navigation buttons that take the capacitive buttons out of the picture.
