The rear camera module is design to carry three sensor, but only a single lens is actually housed in there, and this lens is a Sony IMX319, an 8-megapixel lens with a single LED flash. On the front, there is a single 5-megapixel for selfie duties. Disable the live wallpaper and any third-party themes and use the user interface that came with the phone.

System on Chip (SoC) A system on a chip (SoC) includes into a single chip some of the main hardware components of the mobile device. SoC Information about the manufacturer and model of the image sensor used by this camera of the device. 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. Estimated volume of the device, calculated from the dimensions provided by the manufacturer. Applies for devices in the form of a rectangular parallelepiped.

CPU is the Central Processing Unit or the processor of a mobile device. Its main function is to interpret and execute instructions contained in software applications.

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.

Sometimes a particular app is not made for a particular country or is banned in a country. You have to fix an .apk file by yourself and then try to install it. Information about the number of pixels on the horizontal and vertical dimensions of the photos taken by the front camera, indicated in megapixels as well.

If the phone asks for permission, such as GPS, file access, etc., you need to grant the permission to the app. Display The display of a mobile device is characterized by its technology, resolution, pixel density, diagonal length, color depth, etc. Type/technology If you have slowdown issues when watching a video, lower the quality of the video so that it opens and runs smoothly. Sometimes apps seem to be slow due to poor internet connectivity. Make sure your phone has a proper internet connection.Information about the sensor type of the camera. Some of the most widely used types of image sensors on mobile devices are CMOS, BSI, ISOCELL, etc. It is also possible that your device’s storage is full. Try uninstalling some apps or games from your device. If the phone shuts down after warming up, it may be a heating problem. We have already discussed the solutions to the heating problem. 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.
