Ultimate iPhone Screen Test Guide – Check Touchscreen Health Easily

Part 1. Quick and Easy Ways To Test iPhone Screens

iPhones are expensive devices, and their screens are essential components that should be in top working condition. This section will share some common and easy ways to diagnose issues with your iPhone screen and take appropriate measures to repair or replace it.

Option 1: iPhone Touch Test

An iPhone touch test is the first test that users should perform to check the screen's responsiveness. It is a simple test to determine the touchscreen functionality of an iPhone. This touch screen test can detect any issues with the touch screen, such as dead zones or areas where the screen does not respond to touch. It also checks if the touch points match the actual touch location.

Here are the steps for performing the touch test on your iPhone:

• Step 1: Hold any app icons on your iPhone screen and wait for the X to appear at the corner of your app's icon.
• Step 2: Select any icon and move it randomly across the screen.

Note: If you notice that the icon slips off your finger at any point on the screen, the touch point could already be faulty.

Another way to test is to open the Notes app and select the pen icon to draw a line on the point you suspect is dead touch. You will notice a broken line at the other dead point, signifying that the point is paralyzed.

Option 2: iPhone Render Tests

Another exciting way to perform an iPhone touchscreen test is to check the color of the iPhone screen. Sometimes, it is a common mistake while manufacturing the iPhone rendering the screen color. A common mistake in colors can be yellow, blue, or pink. This color error will affect the overall user experience.

To test iPhone renders, take two iPhones and open the Settings app, and set the brightness to the maximum. Put both iPhones next to each other and compare the two screens' differences. If the color difference is noticeable, the screen has a problem.

Option 3: Check iPhone Exposure

The problem of light exposure goes largely unnoticed by many users, even when it is a common issue. It is likely because the error is not very noticeable on the screen and does not significantly affect the brightness level. The LCD screen assembly causes the error with a non-standard backlight, which leads to light leakage on the sides of the phone screen.

Here are the quick steps to test the light on the iPhone:

• Step 1: Open a black photo and open the camera app.
• Step 2: Cover the shot quickly and increase the screen brightness to the maximum.
• Step 3: Check the edges to see if the screen is open. If it still exhibits a dark edge, the screen is okay. If you notice some light from the phone's edge, your phone suffers from exposure.

Option 4: Built-in Diagnostic Tools

The iPhone comes with several built-in diagnostic tools that you can use to troubleshoot issues and check the health of your device. Besides the basic checks such as battery health, store management, network connectivity, etc., the iPhone has a built-in diagnostic tool called "Screen Test" that allows you to check your device's display and touch functionality.

To access this tool, follow these steps:

• Step 1: Open the Phone app and dial "3001#12345#".

• Step 2: Press the call button, and the Field Test menu will appear.
• Step 3: Tap on Display from the list of options.
• Step 4: Tap on Touch Test to run the screen test.
• The screen test will display several colored boxes on the screen, and you'll need to tap on each box to ensure the touch functionality is working correctly. You can also use the tool to check for dead pixels or other display issues.

Option 5: Call Apple Customer Support

Many iPhone users prefer to seek technical support from Apple's team of knowledgeable professionals when they encounter device problems. You can seek assistance from Apple support by contacting them directly or scheduling an appointment at the Genius Bar in an Apple store. Sometimes, visiting the Genius Bar may be required, especially if you have iOS 10. You must visit the Genius Bar to access diagnostics.apple.com.

To run a diagnostic test, type "diagnostics://" into the Safari browser on your iPhone and enter the service number provided by the technician in the appropriate field. If the test identifies any issues, you can attempt to address them independently (if they are simple enough) or send the phone in for repair.
