This is the official HTC One (M8) User Guide in English provided from the manufacturer. If you are looking for detailed technical specifications, please see our Specs page.
The new HTC One (M8) comes with a radically different than all else 'Duo' camera (this refers to the two rear cameras on its back) that allows you things like selecting the focus of an image after you capture it.The new One also comes with the latest Snapdragon 801 quad-core system chip, an even more intense aluminum unibody construction, and 25% more powerful BoomSound front-facing stereo speakers. And it's not just that - HTC has improved the phone all around, even adding expandable storage via microSD cards of up to 128 gigs. Actually, the only change we can think of in the new One that could possibly bring forth some negativism is the increased overall footprint of the device - it's just larger and a bit bulkier.
