HTC's "Power of 10" event takes place tomorrow, 12 April, and we'll therefore soon see the much-rumoured HTC 10 in the flesh.

Before then though, you can get a glimpse of the flagship phone in a couple of new leaked images that have hit dutch website GSM Helpdesk.

They reportedly show the forthcoming device in black, with the screen on. That's rare in comparison to the other pictures we've seen already.

To be honest, we've seen many leaked handset images over the last few weeks, so little about the design is new, but the phone certainly looks a little thinner than previous generations. And the bezel sort-of wraps around the back more.

It's been noted too that the speaker grilles have gone, but it is strangely reported that the HTC 10 will feature stereo audio and a new form of BoomSound, even though previous rumours have suggested otherwise.

We already know that the processor is made by Qualcomm and is a Snapdragon, although there's not yet confirmation of which one. It is speculated that it will be the 64-bit quad-core Snapdragon 820, with 4GB of RAM, but HTC could surprise us yet.

Another leak last week revealed that the front-facing camera will be the first in the world with optical image stabilisation for the best selfies. GSM Helpdesk claims it will be 5-megapixels.

We'll find out for sure tomorrow. The company is hosting its online-only, livestreamed unveiling from 1pm in the UK, which means it will be 8am in New York and 8pm in Taipei.
