Alleged image from HTC One ultrapixel camera surfaces 

HTC's upcoming flagship device was rumored to feature a stacked sensor with ultrapixels and HTC itself reinforced the rumors by promising new sound and camera experience in 2013. Now, an alleged image taken with the HTC One (or M7 as it was previously known) has shown up on Flickr.

HTC One's ultrapixel camera technology is said to be made up of three 4.3-megapixel sensor layers, which will combine to give a single 4.3 MP image with no interpolation.
The EXIF data of the Flickr image also confirms the rumored HTC One to be the final name of the smartphone. The resolution of the actual image is 1158x2048 pixels, but it's unlikely that is the largest the smartphone is capable of as it's probably downsized.
HTC's press conference on February 19 is certainly an event to keep an eye on. Just make sure you come back when the time comes as we will be covering it live.
