HTC has quietly launched an updated version of the new HTC One. Called the HTC One (M8 EYE), the new model features just one change, but it also happens to be the one that everybody was asking for. HTC has swapped the 4 UltraPixel camera from the original M8 to a new 13 megapixel camera from the Desire EYE but retains the second depth sensor. It also gets the new HTC EYE Experience software from the Desire EYE, but then that is also being made available for the standard M8. Although the original M8 was critically acclaimed for being an excellent smartphone, the UltraPixel camera on the back was universally hailed as being unimpressive due to its low resolution (sometimes megapixels do matter). The latest update fixes that with a three time resolution boost, although low light performance likely won't be as good now. Regardless of that, the M8 EYE is only available in China for now for ¥3,999 ($652) and the only other market where it will be launched is apparently India. So those in other markets might have to import this one, or wait for HTC's next flagship. Source ...
