Instructions

Step 1

Check for a special protective film on the phone screen. Usually there are two of them: the first of them is a special sticker with the name of the product and a description of its main functions, and the second (it is practically invisible) serves to protect the screen of the device. It is usually quite thin. Pay attention to whether its corners are pry and whether there are any signs of interference on it. Also, pay attention to the set backlight level of the phone - usually, by default, the average values for these parameters are set, and the maximum values are already set manually.

Step 2

Check your phone for dropped pixels. To do this, turn on the device, setting the required backlight level, and then carefully study its screen. Small gaps indicate damage in the matrix, so it is best not to purchase a phone with such a screen. Also, there are various third-party utilities to check for dead pixels - this is already relevant for phone owners, and not for buyers.

Step 3

If you purchase a mobile phone with a touch screen, make sure that the icons and menu buttons are in place, that when you click on a particular menu item, the command is executed exactly to the millimeter. Also, when buying a phone, naturally, pay attention to scratches and other traces of mechanical damage.

Step 4

Don't buy a phone without screen protectors. It is possible that it has already been used before. Also, when buying, it is recommended to buy a special protective millimeter film for different types of screens - for touch and ordinary ones, in order to replace the factory sticker with it. In the future, to check the screen during operation, be sure to perform calibration, if available for its model, and install programs for checking dead pixels.
