The exact reason can be determined when disassembling the smartphone. Whatever reason is identified, the loop will have to be replaced.

Software malfunction. With constant flickering, there is a high probability of software failure. Many users do not even realize that this may be the cause of the problem. To eliminate it, the device is checked for viruses, the settings are reset, or the operating system is reinstalled.
