Earlier today we say a posting from Twitter account @OnLeaksdescribing the dimensions of the HTC One M9 Plus, a smartphone that everyone is trying to figure out whether it is going to come to market or not. @OnLeaks has indicated since then that he was able to view a prototype of the HTC One M9 Plus and based on that, he created a mock up showing the device next to the HTC One M9.
As the image reveals, besides the difference in dimensions, the biggest difference is the presence of a button on the front of the HTC One M9 Plus. The lead candidate for that button, that first surfaced in an image back in January, is that it is actually a fingerprint sensor. Whether it serves some other dual purpose, like being a home button or a power button, is unclear.
