⚠️ Before You Start
If your iPhone screen is severely cracked, be careful not to cut yourself on glass fragments. Consider professional repair for badly damaged screens.
🧤 Fix #1: Clean Your iPhone Screen Thoroughly
Dirt, oils, moisture, and invisible residue can interfere with your iPhone's capacitive touchscreen. This simple fix resolves many touch issues.
🧤 Proper Screen Cleaning Method:
- Power off your iPhone completely
- Gather cleaning supplies:
- Microfiber cloth (lint-free)
- Distilled water or isopropyl alcohol (70%)
- Cotton swabs (optional)
- Clean the screen:
- Dampen the microfiber cloth slightly
- Gently wipe the entire screen surface
- Pay attention to the edges and corners
- Use cotton swabs for tight spaces
- Dry completely:
- Use a dry microfiber cloth
- Ensure no moisture remains
- Wait 30 seconds before powering on
💡 Pro Tip
Avoid using paper towels, tissues, or clothing to clean your screen. These materials can scratch the surface and leave lint that interferes with touch sensitivity.
🔄 Fix #2: Force Restart Your iPhone
A force restart clears temporary software glitches that can cause touchscreen problems. This fix works for most software-related issues.
📱 Force Restart by iPhone Model:
📱 iPhone 8 and Later (including iPhone 15):
- Quickly press and release Volume Up
- Quickly press and release Volume Down
- Press and hold the Side button
- Keep holding until you see the Apple logo (10-15 seconds)
- Release the button and wait for restart
📱 iPhone 7 and iPhone 7 Plus:
- Press and hold Volume Down + Side buttons
- Keep holding until you see the Apple logo
- Release both buttons
📱 iPhone 6s and Earlier:
- Press and hold Home + Power buttons
- Keep holding until you see the Apple logo
- Release both buttons
🛡️ Fix #3: Remove Screen Protector and Case
Poor-quality screen protectors or ill-fitting cases can interfere with touch sensitivity, especially around the edges.
🔍 How to Test Accessories:
- Remove the case:
- Carefully remove your iPhone case
- Check if case edges press against the screen
- Test touch response without the case
- Remove screen protector:
- Gently peel off the screen protector
- Start from one corner
- Clean any adhesive residue
- Test touch sensitivity:
- Try all areas of the screen
- Test edge swipes and gestures
- Check if the problem is resolved
ℹ️ Screen Protector Quality
High-quality tempered glass protectors rarely cause touch issues. Cheap plastic protectors are more likely to interfere with touch sensitivity.
📱 Fix #4: Close All Background Apps
Too many apps running in the background can overload your iPhone's memory and cause touchscreen lag or unresponsiveness.
📱 How to Close Background Apps:
🆆 iPhones with Face ID:
- Swipe up from the bottom and pause in the middle
- You'll see the app switcher with open apps
- Swipe up on each app card to close it
- Close all apps, then test touch response
🆆 iPhones with Home Button:
- Double-press the Home button
- Swipe up on each app card to close it
- Press the Home button when finished
⚙️ Fix #5: Adjust Touch Sensitivity Settings
iOS has accessibility settings that can improve touch response for users with motor difficulties or when using screen protectors.
🎛️ Enable Touch Accommodations:
- Go to Settings → Accessibility → Touch
- Tap Touch Accommodations
- Turn on Touch Accommodations
- Adjust these settings as needed:
- Hold Duration - Increase for delayed response
- Ignore Repeat - Prevent accidental multiple taps
- Tap Assistance - Help with tap recognition
- Test the screen response
🔄 Fix #6: Update iOS Software
Apple regularly fixes touchscreen bugs in iOS updates. Installing the latest version can resolve software-related touch issues.
📲 How to Update iOS:

Fix #8: Check for Physical Damage
Success Rate: Variable | Time Required: 3 minutes
Physical damage to the screen or internal components can cause touch issues that require professional repair.

Frequently Asked Questions
Why does my iPhone screen work sometimes but not others?
Intermittent touch issues are usually caused by loose internal connections, software glitches, or partial screen damage. Try the software fixes first, then consider professional diagnosis.
Can a cracked screen protector cause touch issues?
Yes, damaged screen protectors can interfere with touch sensitivity. Remove the protector and test if touch response improves.
How much does iPhone screen replacement cost?
Apple charges $150-329 depending on your iPhone model. Third-party repair shops typically charge $80-200 for screen replacement.
Will a factory reset fix my unresponsive screen?
A factory reset can fix software-related touch issues but won't help with hardware problems. Try other fixes first since a factory reset erases all your data.
