Pictures of the soon-to-be-launched HTC 10 (aka One M10) have emerged online, revealing key details of the device's design language.

Popular Twitter spy Evan Blass has reportedly got hold of the flagship HTC 10's press shots. It shows the device from all angles and confirms the phone will have an all-metal body.

In the picture, we see a ring-shaped primary camera on the rear with dual-LED flash and laser auto-focus, with the HTC brand engraved below it.

On the front, the device houses a physical home with metallic ring, which is understood to house a fingerprint sensor. On the top, a front-camera is placed to the right corner, whereas the speaker is at the centre.

On the edges, we see the phone covered by a metallic frame. The volume rockers and the power button are on right-hand side, whereas the left side has no button.

On the top, the device is shown to house a 3.5mm audio jack port, and at the bottom, it comes with a single-grille speaker to the right, a USB port in the centre and a mic on the left.

There is no credible evidence to suggest the image is of a genuine HTC 10, but the official teaser photo released by the company a few days ago did hint at a chamfered metal chassis, similar to the one shown in the leaked pictures.
