It seems that Desire 820, shown in Berlin, is not the only novelty that HTC is preparing for the next days. The company sends out invitations to the conference, which will take place on October 8 in New York.
The invitation does not reveal too many details. It says only about "double exposure", we can see also two women taking a selfie photo. The phone, which one of them is holding in her hand was deftly covered with rectangles, symbolizing the AF frame in the interface of the camera. But we can see it well enough, to conclude that it is neither Desire 820 from Berlin, nor the HTC tablet, which we have long been gossiping. The phone is a bit like HTC One - but its body seems to be more flattened, without the characteristic arched back profiling. A trained eye can see, however, a dual camera at the back (as in One), as well as a dual LED flash. Unfortunately, at this time we do not know what device it is. We only know that it will be a model dedicated to selfie. Apparently HTC is guarding its secrets much better than Apple.
