Why is my mobile device’s screen showing distorted colors or lines?

Make sure the display settings on the device are set correctly.
Check to see if the device is properly connected to another device if it isn’t connected to a wall outlet.
Switch off and then switch on the device.
Restart the device (turn off and then turn on) and check to make sure the colors appear correct.
Check the device for any visible bends, cracks, or other damage.
Check to ensure the device is not damaged by liquid, pressure, or anything else.
If none of these measures seem to resolve the issue, then contact the device manufacturer or go through the device’s warranty procedures.
