With the official launch next Tuesday, 12 April, it comes as no surprise that official teases, leaks and rumours about the HTC 10 flagship smartphone are ramping up.

One of the latest comes from the horse's mouth itself. Qualcomm has posted a confirmation on its own Twitter feed that the processor is from its Snapdragon family.

Rumours have consistently suggested the new phone will sport the Snapdragon 820 chipset, and with the official tweet at least confirming Qualcomm is on board, that could very well be the case.

The other info about the forthcoming HTC 10 that is now doing the rounds is less official but no less significant.

The Twitter account from photobooth company SmileBooth posted several selfie photos reportedly taken using the new phone (which is called the "HTC 10" on overlaid text). What's more, the main tweet posted on its @testingsmiles account also revealed that the selfie camera with be the world's first with optical image stabilisation.

They look official and SmileBooth might well have been commissioned by HTC to help launch the phone - especially if the improved selfie camera is one of the device's biggest new features. It makes sense to hire a selfie-specialist to help promote it.

What HTC wouldn't have wanted, however, for that company to post the images ahead of the launch, as it seems to have done.

They might not be genuine of course, but it would seem strange to mock them up and further validity comes from the fact that the tweet has now been removed and the Twitter account locked to "protected".

Thankfully, Phandroid managed to grab them and the tweet before they disappeared again, so you can click through them in the gallery above. Job's a good'un.

In all likelihood, we'll see them again soon. 12 April, perhaps?
