Revealing the simplest and most accurate way to test iPhone screen

Testing the iPhone screen is necessary before buying a phone, especially a used one. During use, you should also regularly check the device's screen to avoid serious damage and increased repair costs. If you still don't know how to test the iPhone screen, please follow the article below.

Test iPhone touch

To test iPhone touch, press and hold an app icon on the home screen or press and hold an app and then select rearrange apps. When the 'x' appears, hold and move the icon around the screen. If you see the icon slipping at any point, that could be where the touch screen is dead.

To be more sure about the above check, you can take one more step which is the Notes tool, then draw a few lines in the area where the touch sensor is suspected to be dead. If the drawing line is interrupted in a place where touch is suspected to have died, then it is certain that touch is paralyzed at that place.

Another way to check the iPhone's touch screen is to turn it off and restart it. When an apple appears on the black screen, see if there are any spots around that display other colors such as red, purple, yellow,. or not. If so, the sensor may be dead.

Check the iPhone screen

When testing the iPhone screen, try checking to see if the screen has a blackout error or not. This error causes the screen color to turn blue, yellow or pink. However, this error is quite difficult to detect because the screen only changes color slightly or is affected by external factors.

To check for this error, take two phones, then go to Settings and adjust the brightness to maximum. If there is a screen shadow, you will see that the screen color between the two devices is different, but it is only a very slight color change, so you need to check carefully. In case the device is severely discolored, bring it in for inspection and repair because the screen is seriously damaged.

Check for iPhone screen light leaks

Light leakage is an error in which the backlight light has leaked to the outside at the edge of the screen. The cause of this situation is usually due to the LCD screen and backlight not matching each other. This is one of the errors that is very difficult to detect and often occurs in machines using LCD screens.

To check your iPhone's screen brightness, open a black image and increase the screen brightness to maximum. If you see light rays on the edge of the screen, your screen may be exposed to light.

Quickly check the iPhone screen

When buying a phone, check to see if the iPhone screen is genuine or not. The method is extremely simple, you just need to take out a new phone, then increase the brightness to maximum on both phones and compare. Counterfeit screens are often not as bright as genuine screens, and the clarity and realism of colors cannot be compared.

How to check if the iPhone screen is standard?

If you still feel concerned about the above method of checking a genuine iPhone screen, you can apply another method: drop a few drops of water on the screen. If it is a genuine screen, water will gather at one point. If it is a fake screen, water will spread out.

Above are the simplest and most effective ways to check the iPhone screen. Please apply one of the above methods before deciding to buy so you can own a quality phone!
