Things to Consider

The HTC One M9 is thicker and a bit heavier compared to the other two devices, with its display quality falling between the devices. The HTC One M9’s primary camera has a higher resolution compared to the Galaxy S6 and iPhone 6, and its battery may even last longer than the other two. But there’s one special offering that makes the HTC One M9 standout even more: the Uh Oh Protection.

The Uh Oh Protection offers buyers of the HTC One M9 one free phone replacement within the first 12 months after you purchase the device. It covers cracked screen, water damage and even when changing network carrier. If you don’t use the one free phone replacement in the first 12 months, you get $100 off on your next HTC One purchase.
