The M9 is the first smartphone I've owned that has every feature and quality I've ever wanted out of any phone available. The camera is a big improvement over the M8, and the sound quality is still unmatched by every other phone and even better than it was on the M7/M8. The style and design is stunning! It's lightning fast, has a beautiful screen, allows for HUGE expandable storage and is backed by the best protection of any smartphone out there (HTC Uh Oh...FREE replacement for first 12 months, or $100 towards next phone if you don't get a replacement)! The camera software allows you to create a custom option and save it based on your own preferences. None of the reviews attacking the camera takes this into account when comparing to others...they use default settings so they're not showing you what this camera or its versatile software are capable of. Blinkfeed is more user-friendly than ever and the HTC Themes interface is the perfect all-in-one design studio for your screens, giving you control over wallpaper, icons, fonts and custom themes to personalize your entire experience with ease. Sense Home is an intuitive location-based widget that will display your most commonly used apps (and suggest others) based on your current location (work, home, etc.). Battery life varies based on usage but I've gotten mostly through the day with fairly heavy usage including a lot of streaming and gaming and music listening. This phone has taken a beating by a lot of hypocrites who said the M8 was a stunning design, but now are disappointed that HTC didn't overhaul it. Since when does a stunning design have an expiration date? The M9 doesn't have a quadHD screen but seriously who needs a 5" screen in your pocket that's probably better than your TV at home? The Samsung and iPhone cameras are said to be far better but what sense does it make to ignore everything else that makes a phone great just to have a camera that's only better when strictly compared with another, especially if the M9 CAN take excellent pics? Decide for yourself which is the best phone FOR YOU, don't let Apple and Samsung tell you which is the best or listen to reviews written by people who just follow or favor what's popular.
