This is a little weird, as the XA1 is well-specced for a 720p phone. The MediaTek Helio P20 CPU is an octa-core chip with Cortex-A53 cores, paired with a decent 3GB RAM. The compromise comes in what this little guy is made of. From arm’s length it looks like a full metal phone, but the Xperia XA1 is mostly made of plastic. Only the sides are actually made of the good stuff. However, because your fingertips tend to rest on the aluminium bits, you still get a hint of that hard, dense feel of metal.

Information about the number of pixels per centimeter (ppcm) or per inch (ppi) of the display. The higher the pixel density, the more detailed and clearer is the information displayed on the screen.

Front camera Modern smartphones have one or more front cameras and their positioning has led to various design concepts – pop-up camera, rotating camera, notch, punch hole, under-display camera, etc. Sensor model You also get USB-C for charging, giving it a modern edge over some cheaper rivals that still rely on microUSB. Youngsters probably won't appreciate that holding the phone in landscape means this key is where the shutter button would be on an actual camera, but we know. Focal length is the distance in millimeters from the focal point of the image sensor to the optical center of the lens. The 35 mm equivalent indicates the focal length at which a full-frame camera will achieve an angle of view that's the same as the one of the camera of the mobile device. It is measured by multiplying the native focal length of the camera by the crop factor of the sensor. The crop factor itself can be determined as the ratio between the diagonal distances of the image sensor in the 35 mm camera and a given sensor. One of the main characteristics of the cameras is their image resolution. It states the number of pixels on the horizontal and vertical dimensions of the image, which can also be shown in megapixels that indicate the approximate number of pixels in millions.
