Are you having trouble with your iPhone touch screen not working? You're not alone. Many iPhone users experience this frustrating issue, and it can be caused by a variety of factors. Fortunately, there are several solutions you can try to fix the problem. In this article, we'll walk you through some troubleshooting steps to help you get your iPhone touch screen working again.
Apple’s iPhone is one of the most popular smartphones in the world today. One of the most significant features that make iPhone stand out is its touch screen. The iPhone touch screen is not just any ordinary screen, but it is a capacitive touch screen, which is more responsive and accurate than the resistive touch screens found in other smartphones.
How Does the iPhone Touch Screen Work?
The iPhone touch screen works by using a layer of capacitive material placed over the display panel. This layer of material is divided into a grid of tiny electrodes that are connected to a controller chip. When you touch the screen, the controller chip detects the change in the electrical field at the point of contact and calculates the location of the touch.
The iPhone touch screen also uses a technology called in-plane switching (IPS) to improve the display quality. IPS technology ensures that the colors and brightness of the screen remain consistent, even when viewed from different angles.
The first iPhone, which was released in 2007, used a 3.5-inch touch screen with a resolution of 320×480 pixels. The touch screen had a pixel density of 165 pixels per inch (ppi). The iPhone touch screen has evolved significantly since then. The latest iPhone, the iPhone 13, features a 6.1-inch touch screen with a resolution of 1170×2532 pixels and a pixel density of 460 ppi.

How Has the iPhone Touch Screen Evolved Over Time?
The iPhone touch screen has undergone significant improvements over the years. Here are some of the major changes:
-
Retina Display
In 2010, Apple introduced the Retina Display on the iPhone 4. The Retina Display was a significant improvement over the previous iPhone touch screens. It had a resolution of 640×960 pixels and a pixel density of 326 ppi, making the individual pixels indistinguishable to the human eye when viewed at a normal distance.
-
3D Touch
In 2015, Apple introduced 3D Touch on the iPhone 6s. 3D Touch allowed users to interact with the touch screen in new ways by measuring the pressure of the touch. The touch screen could distinguish between a light tap, a firm press, and a deeper press, allowing for new gestures and actions.
-
OLED Display
In 2017, Apple introduced the OLED display on the iPhone X. OLED displays are known for their high contrast ratios, deep blacks, and vibrant colours. The iPhone X had a resolution of 1125×2436 pixels and a pixel density of 458 ppi.
-
Haptic Touch
In 2018, Apple replaced 3D Touch with Haptic Touch on the iPhone XR. Haptic Touch uses long presses and vibrations to simulate the feel of a physical button press. Haptic Touch is less complex than 3D Touch, but it still allows for new gestures and actions.
Why is iPhone Touch Screen Not Working?
-
Software Issues
One of the most common reasons why the iPhone touch screen may not be working is due to software issues. These can be caused by a variety of factors, such as a software update that did not install correctly, a glitch in the operating system, or an app that is causing the system to crash. In these cases, the touch screen may not respond or may only respond intermittently.
-
Physical Damage
Another reason why the iPhone touch screen may not be working is due to physical damage. If the screen is cracked, scratched, or otherwise damaged, it may not respond to touch properly. Similarly, if the device has been dropped or subjected to other forms of impact, the touch screen may be damaged internally.
-
Moisture Damage
Moisture damage is another common reason why the iPhone touch screen may not be working. If the device has been exposed to water or other liquids, the touch screen may become unresponsive. In some cases, the device may need to be completely replaced if the damage is severe.
-
Touch Screen Calibration
Finally, the touch screen may not be working properly due to calibration issues. If the device has been dropped or jostled, the touch screen may be misaligned or may need to be recalibrated. This can cause the touch screen to be unresponsive or to respond incorrectly to touch commands.
How to Fix iPhone Touch Screen Not Working
Step 1: Restart Your iPhone
The first thing you should try when your iPhone touch screen isn't working is to restart your device. To do this, press and hold the power button until the “slide to power off” option appears on the screen. Slide the button to turn off your iPhone, then press and hold the power button again to turn it back on. This simple step can often solve touch screen issues caused by software glitches.
Step 2: Clean Your Screen
Another common reason for touch screen problems is a dirty or greasy screen. Your iPhone's touch screen is sensitive to oils and dirt, which can interfere with its functionality. To clean your screen, use a microfiber cloth or lens cleaning wipe. Avoid using abrasive materials like paper towels or rough cloths, as they can scratch your screen.
Step 3: Remove Your Case and Screen Protector
If you have a case or screen protector on your iPhone, it may be interfering with your touch screen's sensitivity. Try removing your case and screen protector to see if that fixes the issue. If it does, consider getting a new case or screen protector that won't interfere with your touch screen.
Step 4: Update Your iOS
Outdated software can cause a variety of issues with your iPhone, including touch screen problems. Make sure your iPhone is running the latest version of iOS by going to Settings > General > Software Update. If there is an update available, tap “Download and Install” to update your software.
Step 5: Reset Your iPhone's Settings
If none of the above steps works, you may need to reset your iPhone's settings to fix the touch screen issue. To do this, go to Settings > General > Reset > Reset All Settings. This will reset your iPhone's settings to their default values but won't delete any of your data or media.
Step 6: Restore Your iPhone
If the touch screen issue still persists, you may need to restore your iPhone to its factory settings. This will erase all of your data and media, so make sure you have a backup before proceeding. To restore your iPhone, connect it to your computer and open iTunes. Click on your iPhone in the sidebar, then click “Restore iPhone.” Follow the on-screen instructions to complete the restore process.
Step 7: Contact Apple Support
If none of the above steps works, your iPhone touch screen may have a hardware issue that requires professional repair. Contact Apple Support to schedule a repair appointment at an Apple Store or authorized service provider.
Conclusion
There are several steps you can take to fix your iPhone touch screen when it's not working. Try restarting your iPhone, cleaning your screen, removing your case and screen protector, updating your iOS, resetting your iPhone's settings, or restoring your iPhone to its factory settings. If none of these steps work, contact Apple Support for professional repair assistance.
