Why does cellphone display green screen color?

A cellphone display may show a green screen due to several reasons, such as hardware malfunctions, software glitches, or issues with the display's connection or circuitry. This can occur if the display driver fails, or if there are problems with the graphics processing unit (GPU). In some cases, a green screen can also result from corrupted software or incompatible apps. Restarting the device or performing a factory reset may help resolve the issue, but hardware repairs might be necessary if the problem persists.
