HTC may debut HTC Desire 8 on 24th February 2014 if the hints are correct. There are a few images sent from HTC Weibo account that, based on the Chinese characters, may indicate that it is a HTC Desire 8 series.
And on another photo, it has a weather forecast that shows 24th February 2014 10am Beijing. So, I think this might be the clue that the HTC Desire 8 is going to debut on that date. Some information from Ubergizmo: –
In terms of specs, we have heard how the HTC Desire 8 might pack a 5.5-inch display with unknown resolution. It will also feature a 13MP rear-facing camera, a 5MP front-facing camera, and will apparently be available in a variety of different colors, such as white, red, yellow, orange, and cyan. Based on the design, the HTC Desire 8 will also pack front-facing stereo speakers which is reminiscent of the HTC One.
So, hopefully, we can see this handset soon. Actually, after looking at HTC Weibo account, I think the HTC Desire 8 is no secret. They are actually having some online activities from 17th February to 21st February talking about this phone.
