Information about additional software and hardware features of the rear camera which improve its overall performance. UMTS HSPA+ 850 (Band V), 900 (Band VIII), 1900 (Band II), 2100 (Band I) MHz GSM GPRS/EDGE 850, 900, 1800, 1900MHz LTE (Bands 1, 3, 5, 7, 8, 28, 38, 39, 40, 41M) The device features a 5.0-inch 720p screen and a 64-bit 2.0GHz octa-core Mediatek MT6755 (Helio P10) system-on-chip with 2GB of RAM. The device also has 16GB internal storage with microSD card expansion up to 200GB and includes non-removable 2300 mAh battery. [2]
This is a real shame, as Sony’s displays have consistently been one of its key strengths. Sadly, the XA also lags behind on brightness, topping out at 407.43cd/m2. This is by no means terrible, and still just about good enough to see the screen clearly outdoors in direct sunlight, but when the Xperia X, M5 and even 2014’s M4 Aqua all broke 500cd/m2, the XA once again feels quite dull by comparison. Contrast was reasonably good and I measured a ratio of 1,119:1, so at least you get a decent gradient between lights and darks. RAM (Random-Access Memory) is used by the operating system and all installed applications. Data in the RAM is lost after the device is turned off or restarted. Networks A mobile (cellular) network is a radio system, which allows a large number of mobile devices to communicate with each other. GSM The Xperia XA is preinstalled with Android 6.0.1 Marshmallow with Sony's custom interface and software. [4] On August 23, 2016, Sony announced that the Xperia XA would receive an upgrade to Android 7.0 Nougat. [5] On June 16, 2017, it was reported that Android 7.0 Nougat was rolling out to the Xperia XA. [6] Variants [ edit ] Sign in to the Google account that is registered on your smartphone.

⚙️ Processor
The color depth of the display is also known as bit depth. It shows the number of bits used for the color components of one pixel. Information about the maximum number of colors the screen can display. Similar to the CPU, the GPU consists of processing units called cores. They handle the computation of graphics in various applications. It’s a shame, then, that the XA’s 5in, 1,280×720 display is nowhere near as good as those used in rest of Sony’s 2016 smartphones. Covering just 81.3% of the sRGB colour gamut, it simply doesn’t have the same depth of colour as the Xperia X, and it even falls behind the Xperia M5, Sony’s other mid-range handset we reviewed earlier in the year, which covered 92.2%.
In photography, the Field of view (FoV) depends not only on the focal length of the lens but also on the sensor size. It is derived from the lens's angle of view and the sensor's crop factor. The lens's angle of view is a measure of the angle between the two farthest separated points within the frame measured diagonally. Simply put, this is how much of a scene in front of the camera will be captured by the camera's sensor. 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. How to use the Find My Device app to reset my Xperia phone What do I need to reset my phone this way? The L2 (level 2) cache memory is slower than L1, but has a larger capacity, instead, which allows it to cache more data. Just like L1, it is much faster than the system memory (RAM). If the CPU does not find the data needed in L2, it proceeds to look for them in the L3 cache memory (if there is such) or in the RAM. Specific Absorption Rate (SAR) The SAR rating shows the amount of electromagnetic radiation absorbed by the human body when using a mobile device, expressed in W/kg. Head SAR (EU)

UMTS HSPA+ 850 (Band V), 900 (Band VIII), 1900 (Band II), 2100 (Band I) MHz GSM GPRS/EDGE 850, 900, 1800, 1900MHz LTE (Bands 1, 2, 3, 5, 7, 8, 20) The display resolution shows the number of pixels on the horizontal and vertical side of the screen. The higher the resolution is, the greater the detail of the displayed content. Tip: If you can’t turn off your Xperia device before performing a software repair, force it to shut down. To shut down, press and hold down the power key and the volume up key simultaneously until the device emits three vibrations.
➕ Other features
Battery The batteries of mobile devices differ in capacity and technology. They provide the electrical charge needed for the functioning of the devices. Capacity Estimated volume of the device, calculated from the dimensions provided by the manufacturer. Applies for devices in the form of a rectangular parallelepiped.
UMTS stands for Universal Mobile Telecommunications System. Based on the GSM standard, it is deemed as a 3G mobile network standard. It has been developed by the 3GPP and its major advantage is the provision of greater bandwidth and spectral efficiency, due to the W-CDMA technology. The rear cameras of mobile devices use mainly a LED flash. It may arrive in a single, dual- or multi-light setup and in different arrangements. Display The display of a mobile device is characterized by its technology, resolution, pixel density, diagonal length, color depth, etc. Type/technology 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.The aperture (f-stop number) indicates the size of the lens diaphragm opening, which controls the amount of light reaching the image sensor. The lower the f-stop number, the larger the diaphragm opening is, hence, the more light reaches the sensor. Usually, the f-stop number specified is the one that corresponds to the maximum possible diaphragm opening.
