First, check the screen for scratches, cracks, or scuffs. Gently touch the screen surface with your finger to feel for any uneven areas. At the same time, observe whether there is glue leakage or looseness on the edge of the screen.
2.show test
Open a solid color picture (such as white, black, red, etc.), display it in full screen, and check whether there are dead pixels, bright spots, or color spots. Dead pixels usually appear as small black spots or bright spots that do not change with the screen content.
3.Touch function test
Open your device's Drawing app or Notes and slide your finger across the screen to check for areas that are insensitive or disconnected. Also, test multi-touch functions such as zooming in and out of images.
4.Automatic brightness adjustment
Turn on automatic brightness adjustment in settings, cover the light sensor (usually located at the top of the screen) with your hand, and see if the screen brightness changes accordingly. If there is no change in brightness, the sensor may be faulty.
5.True Tone and original color display
