In Short

HTC at Mobile World Congress 2015 in Barcelona, Spain, announced the all-new HTC One M9. While it might look a good bit like its predecessor (why mess with a good thing, right?) there's still a lot going on here.

The phone is slightly smaller and easier to hold. The rear UltraPixel camera has been swapped out for a more traditional 20MP shooter. Sense 7 gives you so many new ways to share and edit photos, and it's easier to do now as well.

BoomSound is back, of course, and this time Dolby is on board to help with the audio lifting.

The HTC One M9 is coming to major carriers worldwide in mid-March.
