CAMERA: The Xperia X Performance has a single 23-megapixel camera. The camera has optical image stabilization to improve your chances of taking better handheld photos under low-light conditions. Overall the camera performance was good, below that of many other models but still good enough for most users to capture fine still shots. Images are evaluated on high quality LCD displays. The test photos are taken in a brightly lit studio and outdoors on a sunny day. In the viewing tests the images were rated good overall. These images offer acceptable results for color quality, exposure level, sharpness, and image noise but the images are not among the better cameras on smartphones.

DISPLAY: Overall the display quality was very good. The display resolution was high enough, close to or greater than 300dpi, so you see a smooth, crisp display but it didn't appear quite as crisp as our best displays. If the display does have a higher resolution, most people will not be able to tell the difference. Readability outdoors is a combination of brightness, measured in candelas per square meter, and reflectivity. The readability rating was very good. Brightness was a very high 520cd/m² and reflective glare was minimal.
