Barely 24 hours are left to go before HTC unveils its new smartphone, the HTC 10, and the official launch video has leaked.

The leaked video, slipped out via Reddit, shows off the new HTC 10 in a way that reminds us of many launch events gone before. This is most likely the video that will used to wow fans watching the event tomorrow.

If you don't want spoilers stop reading now.

The video shows the phone being created from a single block of metal – something HTC has taken pride in since its unibody HTC One wowed the world. The shiny metallic edging finish appears to be laser cut with a rougher grip-friendly rear.

Also seen is the single rear camera, USB-C port, drilled speaker, a ribbed power button on the side plus a front-facing home button that should double as a fingerprint reader. The handset is seen running the new version of HTC Sense skinned over Android Marshmallow. 

Other specs leaked include a 5.2-inch QHD display, 12-megapixel UltraPixel camera, Qualcomm Snapdragon 820 chip with 4GB of RAM plus a Quick Charge 3.0 compatible battery.

For the full details on the HTC 10, as well as hand-on coverage live from the event tomorrow, check back for a 1PM BST launch on 12 April.
