Review: HTC One S for T-Mobile
The One S and One X have identical camera chips and software. For whatever reason, I was more impressed with the results from the One S. I thought it did a fine job of focusing and exposing images correctly, and vital elements such as white balance were also spot on. Colors looked a little muted from time to time, but the bulk of shots I captured were bright and cheery. The huge array of tools available mean that your results are only limited by your own creativity. Get out there with the One S, take pictures, and share them. They're worth it.
For lovers of HD video, you'll be happy to learn that the One S shoots at a max resolution of 1080p. I thought the video looked good, though it was overly sharp at times, and prone to a jittery look if you don't hold the device still enough. Bottom line, though, is that you'll be happy to upload to YouTube.
