Having a 4-megapixel sensor with fewer megapixels forces each pixel to be larger, letting in more light, according to HTC.
Analysts agreed that HTC is correct in saying that megapixels aren't the only factor in a good camera. HTC cited other camera features, including optical image stabilization and a smart flash with five levels of flash that are automatically set by the distance to a subject.
"Megapixels alone in a camera are not enough: You need good software, lenses and sensors to make the experience rich," Milanesi said.
"There's definitely truth to the argument that sensor size is more important than raw pixel count," Gartenberg said. "That's true in dedicated cameras. If HTC implemented well, it could make a difference, especially in low light."
HTC didn't stop at a good camera in the One. The phone maker also mentioned audio improvements with Boomsound, which includes dual front stereo speakers enhanced with Beats Audio technology.
The phone also comes with a quad-core Qualcomm Snapdragon 600 processor, rated at 1.7 GHz, and a 2,300 mAh battery. LTE networks are supported on all three U.S. carriers, and near-field communications technology is available, depending on the carrier and the location.
The HTC One weighs 5.04 ounces, and measures 5.41 x 2.69 x 0.37 inches.
