Wow! HTC remove all duplicated apps and use mostly Google Apps like email, calendar, calculator, Google photos and more rather than HTC apps that provide the same features to prevent bloat and waste space, more close to stock Android experience with HTC tweaks not like the Galaxy.
It's also the first Android phone to support Apple AirPlay Audio streaming. Well, the dark grey version looks good but design wise not as beautifully crafted as Galaxy S7 Edge BUT better than ugliest LG G5, that fake aluminium phone in disguise as it actually plastic.
