Many iPhone users are experiencing dead spots on their touchscreens. There is often a vertical line running the entire length of the screen in these dead zones. It may seem that your touchscreen isn’t responding to touch properly.
Select a marker when you start a new note. Make scribbles on your screen by moving your finger across it. There will be a blank strip corresponding to the dead zone.
How to Get Rid of Dead Spots on Your iPhone Screen?
The possibility of physical damage is one of the possibilities. Accidental damage to an iPhone is often associated only with things that can be seen, such as a cracked screen. However, It is possible for things like drops to damage the components inside the phone. Your phone can get damaged even if you’ve never dropped it, such as if you sit on it while it’s in your back pocket. Further, a damaged phone may not exhibit symptoms immediately.
Manufacturing defects are another possibility, although they are rare. It is very important that you take your iPhone to a repair or replacement shop if you haven’t had it very long, and it hasn’t been dropped or otherwise damaged. Products from Apple are covered by a one-year limited warranty.
Quick Ways to Test All iPhone Version Mobile Screens
Having a well-functioning screen on an iPhone is a necessity since iPhones are expensive devices. Following is a list of common and easy ways to diagnose iPhone screen issues and take appropriate measures to fix or replace them.
01. iPhone Touch Test
The iPhone touch test is the first test users should perform to ensure the screen is responsive. iPhone touchscreens can be tested using a simple test to determine whether they are functional. A touch screen test detects any issues with the screen, such as dead zones or non-responsive areas. The touch points are also checked to see if the actual locations match the touch points.

Performing the touch test on your iPhone is as simple as following these steps:
- On your iPhone screen, hold any app icon and wait until an X appears in the corner
- You can move any icon across the screen by selecting it and dragging it randomly
Note: Whenever the icon slips off your finger on the screen, it could already be faulty.
02. iPhone Render Tests
Performing an iPhone touchscreen test also involves checking the iPhone screen’s color. Sometimes, a mistake is made during the iPhone’s manufacturing process. It is common to mistake yellow, blue, or pink for other colors. A color error like this will negatively impact the user experience.
In order to test iPhone renders, it’s best to open the Settings app on two iPhones, and set the brightness to maximum. Compare the two iPhones next to each other and see where the differences are between them. The screen may have a problem if the color difference is noticeable.
03. Check iPhone Exposure
Although light exposure is a common problem, many users fail to notice it. In this case, it may not affect the brightness level significantly or may not be very noticeable. Due to a non-standard backlight in the LCD screen assembly, the error results in light leaking from the sides.
The light on the iPhone can be tested by following these steps:
- The camera app should be open after you have opened a black photo.
- Snap the shot quickly and set the screen brightness to maximum.
- Make sure the screen is open by checking the edges. A phone could have been exposed if you notice light coming from the edge.
04. Integrated diagnostics
Diagnostic tools are built into the iPhone to troubleshoot problems and assess its health. Using the built-in “Screen Test” tool, you can check your iPhone’s display and touch functionality as well as battery life, store management, and network connectivity.
Here are the steps you need to follow to get access to this tool:
- To access the Phone app, open it and dial “3001#12345#”
- When the call button is pressed, a menu will appear for Field Tests
- There is an option called Display in the options list
- Running a screen test is as simple as tapping on Touch Test
- Touch functionality will be tested through multiple colored boxes on the screen, so tap each box to see if it works
05. Contact Apple Customer Support
Most iPhone users seek technical support from Apple’s knowledgeable professionals. Apple support is available directly from Apple or through an appointment at the Genius Bar at an Apple store.
You must enter the service number provided by the technician into the Safari browser on your iPhone to run a diagnostic test. If any issues are detected during the test, you can fix them yourself (if they are simple enough) or send the device to a technician for service.
