Quick Answer
If your iPhone screen does not respond to taps or swipes, first disconnect charging accessories, remove the case and screen protector, and make sure the display is clean and dry. If the entire screen remains frozen, perform the correct force-restart procedure for your iPhone model. Persistent dead areas, ghost touches, or problems following a drop or display replacement may require professional inspection.
Possible causes include a temporary software freeze, moisture or debris on the display, a poorly fitted screen protector, an accessory or charger problem, accessibility settings, or damage to the touch-sensitive display hardware. The supplied possible cause of digitizer failure or a software freeze should be treated as a diagnostic hypothesis rather than a confirmed diagnosis.

Safety Check
Stop using the iPhone and arrange professional inspection if you notice:
- A raised or bulging screen
- A swollen back panel
- Smoke, sparks, or a burning smell
- Extreme or rapidly increasing heat
- Exposed internal components
- Sharp or loose glass
- Liquid visible inside the display or charging port
- Severe damage after a drop, crushing force, or impact
- A screen that is separating from the frame
Do not press a raised screen back into place. Battery swelling can push the display away from the frame, and continued pressure or charging may be unsafe.
Do not open the iPhone, disconnect internal display cables, or replace the display assembly as routine beginner troubleshooting. Apple recommends trained repair providers for display replacement because incorrect parts or repair procedures can affect display function and device safety.

1-Minute Safe Checks
- Disconnect all Lightning or USB-C accessories.
- Remove the case, screen protector, magnetic wallet, and attached accessories.
- Make sure the screen and your hands are clean and dry.
- Wipe the display gently with a clean, dry, soft cloth.
- Lock and wake the iPhone using the side button.
- Test whether the entire screen or only one area is affected.
- Check whether the problem occurs in one app or throughout iOS.
- If the entire screen is frozen, perform a force restart.
Apple’s official screen-troubleshooting guidance recommends restarting the device, cleaning and drying the screen, disconnecting accessories, and removing cases or screen protectors before arranging service.
Fix 1: Clean the Screen and Remove Accessories
SAFE FIRST CHECK
Use This When
Use this step when:
- Touch works intermittently
- The screen registers the wrong location
- Ghost touches appear
- The problem began after installing a screen protector
- The screen is wet, oily, or dirty
- Touch fails mainly while the charger is connected
- A thick or damaged case presses against the display
Why It May Help
Water, debris, a damaged protector, case pressure, or a connected accessory may interfere with normal touch input. Apple specifically recommends making sure the screen is clean and dry, disconnecting Lightning or USB-C accessories, and removing cases and screen protectors.
Steps
- Disconnect the charging cable, adapter, headphones, storage device, or other wired accessory.
- Remove the case.
- Remove a cracked, lifted, bubbled, or poorly aligned screen protector.
- Make sure your hands are clean and dry.
- Wipe the screen using a clean, dry, soft cloth.
- Do not pour cleaning liquid directly onto the display.
- Do not insert liquid around the edges of the screen.
- Wake the iPhone and test several areas of the display.
- Open different apps and test tapping, typing, scrolling, and swiping.
- If touch works after disconnecting the charger, test another known-good cable, adapter, and wall outlet.
- Change only one charging component at a time so you can identify which item affects the result.
Expected Result
Touch input should become consistent after moisture, debris, accessory pressure, or charging interference is removed.
What the Result Means
- If removing the case or protector fixes the problem, the accessory was interfering with normal touch input.
- If disconnecting the charger fixes the problem, the charging setup becomes a possible contributor. Try another compatible outlet, cable, and charger, as Apple recommends.
- If the same area of the screen remains unresponsive in every app, continue with the force restart and hardware-related checks.
- This test does not prove that the display hardware is healthy. Intermittent hardware problems may temporarily disappear.
Fix 2: Force Restart the iPhone
OFFICIALLY DOCUMENTED STEP
Use This When
Use this step when:
- The entire screen is frozen
- Taps and swipes do nothing
- The iPhone displays an app or page but cannot be controlled
- The side or Home button still responds
- The problem appeared without visible physical damage
Why It May Help
A force restart restarts the iPhone without requiring touchscreen input. It can clear a temporary system or app freeze.
A force restart is not a factory reset and does not intentionally erase your apps, photos, accounts, or settings.
Steps for iPhone 8 or Later and iPhone SE, 2nd Generation or Later
- Press and quickly release the Volume Up button.
- Press and quickly release the Volume Down button.
- Press and hold the Side button.
- Continue holding until the Apple logo appears.
- Release the Side button when the Apple logo appears.
Steps for iPhone 7 and iPhone 7 Plus
- Press and hold the Side button and Volume Down button together.
- Continue holding both buttons until the Apple logo appears.
- Release the buttons when the logo appears.
Steps for iPhone 6s or Earlier and iPhone SE, 1st Generation
- Press and hold the Home button.
- At the same time, press and hold the Side or Top button.
- Continue holding until the Apple logo appears.
- Release both buttons when the logo appears.
These button combinations are documented by Apple for restarting unresponsive iPhone models.
Expected Result
The iPhone should restart and display the Lock Screen. Test tapping, typing, swiping, and scrolling after startup.
What the Result Means
- If touch works normally after the restart, a temporary software freeze may have contributed.
- This does not prove that the screen hardware is fault-free. Watch for the problem returning in the same app, during charging, or in the same physical area of the display.
- If the screen remains completely unresponsive after restarting, continue with the physical and hardware checks.
- If the buttons are also damaged or the iPhone cannot restart, professional service may be required.
Fix 3: Determine Whether One App or the Whole Screen Is Affected
DIAGNOSTIC TEST
Use This When
Use this test when the touchscreen works on the Home Screen but stops responding inside one app.
Why It May Help
A single frozen app requires a different troubleshooting path from a device-wide touchscreen problem. If gestures work normally outside the affected app, the display hardware is less likely to be the only explanation.
Apple recommends closing and reopening an unresponsive app, restarting the device, and checking for app or iOS updates.
Steps
- Try returning to the Home Screen.
- Open Control Center or Notification Center.
- Test another app.
- If other areas respond normally, reopen the affected app.
- Open the App Switcher:
- On an iPhone without a Home button, swipe up from the bottom and pause.
- On an iPhone with a Home button, double-press the Home button.
- Swipe up on the affected app to close it.
- Open the app again.
- Open the App Store.
- Tap your profile picture.
- Install an available update for the affected app.
- Restart the iPhone if the app freezes again.
- Update iOS if the app developer requires a newer compatible version.
Expected Result
If the issue is app-specific, touch should continue working normally throughout the rest of the iPhone.
What the Result Means
- If only one app freezes, troubleshoot that app rather than treating the display as failed.
- If the same area of the screen does not respond in every app, a screen protector, display, connector, or touch-sensing hardware issue becomes more plausible.
- Deleting and reinstalling an app is not included as an early step because locally stored app data may be lost. Apple warns that deleting an app may remove data stored inside it.
Fix 4: Review Touch Accommodations
CONDITIONAL STEP
Use This When
Use this step when:
- The screen responds only after holding a finger down
- Quick taps appear to be ignored
- Repeated taps are treated as one tap
- Swiping behaves differently than expected
- The problem began after Accessibility settings were changed
- The touchscreen still responds enough to open Settings
Why It May Help
Touch Accommodations intentionally changes how the iPhone responds to taps, repeated touches, swipe movement, and touch duration. Settings such as Hold Duration, Ignore Repeat, and Tap Assistance can make normal taps seem delayed or unresponsive when configured unintentionally.
Steps
- Open Settings.
- Tap Accessibility.
- Tap Touch.
- Tap Touch Accommodations.
- Check whether Touch Accommodations is enabled.
- Review:
- Hold Duration
- Swipe Gestures
- Ignore Repeat
- Tap Assistance
- Temporarily turn off Touch Accommodations.
- Test normal taps, swipes, typing, and scrolling.
- Re-enable the feature if you rely on it for accessibility.
- Adjust its settings carefully rather than leaving it disabled when it is needed.
Expected Result
Normal touch timing should return if an accessibility setting was intentionally delaying or filtering input.
What the Result Means
- If disabling Touch Accommodations fixes the issue, the touchscreen itself may not be defective.
- If the same physical area remains dead regardless of the setting, continue with software updates and display inspection.
- This comparison does not rule out intermittent hardware damage.
Fix 5: Update iOS When Touch Still Works Intermittently
CONDITIONAL STEP
Use This When
Use this step when:
- Touch works well enough to operate Settings
- The problem is intermittent rather than completely constant
- The issue began after an app or software change
- The display has no obvious physical damage
- A backup can be completed first
Why It May Help
An iOS update may include system fixes, security updates, and compatibility improvements. Updating is reasonable when safer physical and restart checks have already been completed.
Do not attempt an update while the iPhone is repeatedly restarting, dangerously hot, liquid-damaged, or unable to maintain a stable connection.
Steps
- Back up the iPhone using iCloud or a computer.
- Connect the iPhone to a reliable Wi-Fi network.
- Connect it to a known-good charger if needed.
- Open Settings.
- Tap General.
- Tap Software Update.
- Review the available update.
- Tap Download and Install when an update is available.
- Follow the onscreen instructions.
- After the update, test the entire screen in multiple apps.
Apple’s current update instructions recommend backing up first, connecting to Wi-Fi and power, and using Settings > General > Software Update.
Expected Result
If a software fault contributed to the problem, touch response may stabilize after the update and restart.
What the Result Means
- Improvement after updating supports a software-related contribution but does not prove that software was the only cause.
- If the same area remains unresponsive after the update, the result points away from a temporary system freeze.
- Do not perform a factory reset or full restore as routine troubleshooting for a screen with persistent dead zones, visible damage, ghost touches, or problems following a drop. A restore cannot repair damaged display hardware and may create unnecessary data-loss risk.
Fix 6: Check Display Repair History
DIAGNOSTIC TEST
Use This When
Use this step when:
- The touchscreen problem began after a screen replacement
- Touches register in the wrong location
- Parts of the display miss taps
- Ghost touches began after repair
- The screen has an Unknown Part or service notification
- You bought the iPhone used and do not know its repair history
Why It May Help
Apple states that display quality, repair procedure, and part compatibility can affect Multi-Touch performance. Potential issues can include missed touches, touch failure in parts of the screen, inaccurate touch locations, or accidental touch registration.
Steps
- Open Settings.
- Tap General.
- Tap About.
- Look for Parts and Service History.
- Check whether a Display entry is shown.
- Note whether the display is labeled:
- Genuine
- Used
- Unknown
- Finish Repair
- If the touchscreen problem started immediately after a repair, contact the original repair provider.
- Explain exactly which part of the screen fails and whether the problem occurs in every app.
- Avoid opening the iPhone or reseating internal display cables yourself.
Parts and Service History is available only on supported models and software versions, and the exact parts shown vary by iPhone model.
Expected Result
The settings may identify a previous display repair or show that the installed display is not functioning or verified as expected.
What the Result Means
- An Unknown or incomplete repair message does not independently prove that the replacement display caused the touchscreen problem.
- However, if touch problems began immediately after display service, the repair, part, connection, or calibration should be professionally checked.
- A Genuine label also does not guarantee that the display has no physical or intermittent fault.
When the Problem May Be Hardware-Related
Professional inspection becomes appropriate when:
- The same area of the screen remains unresponsive in every app
- Touch remains dead after a force restart
- The screen responds only when the frame is pressed or twisted
- Ghost touches continue with the screen clean and accessories removed
- The display is cracked, lifted, or separating from the frame
- The problem began immediately after a drop or impact
- Lines, flickering, discoloration, or black areas appear with touch failure
- The iPhone was exposed to liquid
- Touch fails with several chargers and while disconnected from power
- The issue started after a display replacement
- Parts and Service History shows an Unknown or unfinished display repair
- The screen works intermittently as the phone warms up or moves
- Touch becomes progressively worse
These signs can support a display-assembly, connector, or touch-sensing hardware possibility, but they do not identify the exact failed component without inspection.
Apple advises arranging service when the screen still does not work after restarting, cleaning it, disconnecting accessories, and removing cases or screen protectors.
When to Stop DIY Troubleshooting
Stop home troubleshooting when:
- The screen is bulging or separating from the frame
- The iPhone becomes abnormally hot
- Smoke, sparks, or an unusual smell appears
- Glass is loose or sharp
- Liquid is visible inside the phone
- Touch failure followed severe physical impact
- Important data is not backed up and the next action could erase it
- The iPhone requires opening to continue diagnosis
- The screen cannot be controlled well enough to safely back up or update
- Random touches could enter the wrong passcode repeatedly
- The phone begins calling, typing, or selecting items without input
If ghost touches are entering passcodes or opening apps, lock the iPhone with the side button and stop using it until it can be inspected.
Common Mistakes
- Assuming a frozen screen automatically means digitizer failure
- Assuming a restart proves the display is healthy
- Continuing to use a cracked or separating screen
- Pressing hard on a dead area of the display
- Twisting the phone to make touch work temporarily
- Heating or cooling the screen
- Applying liquid directly to the display
- Testing while the screen or hands are wet
- Leaving a damaged screen protector installed
- Ignoring a problem that occurs only while charging
- Performing a factory reset before checking physical damage
- Reinstalling multiple apps when the whole screen is affected
- Opening the iPhone to reseat display connectors
- Buying a replacement screen before confirming the exact symptom
- Entering the passcode repeatedly while ghost touches are active
Frequently Asked Questions
Why is my iPhone screen on but not responding?
The iPhone may be experiencing a temporary software freeze, moisture or debris on the screen, case or screen-protector interference, charger-related interference, an accessibility setting, or display damage.
Will a force restart erase my data?
A force restart is not a factory reset. It restarts the iPhone using its physical buttons and does not intentionally erase personal content. It cannot repair a cracked display, damaged touch hardware, or a loose internal connection.
Why does the touchscreen stop working while charging?
Apple recommends disconnecting Lightning or USB-C accessories when the screen responds intermittently. If touch works normally after disconnection, compare another outlet, cable, and charger. The comparison identifies an accessory-related pattern but does not confirm which electrical component is responsible.
Does one dead area mean the digitizer has failed?
Not necessarily. First remove the protector and case, clean and dry the screen, restart the iPhone, and test the same area in multiple apps. A dead area that remains in exactly the same location across the Lock Screen, keyboard, Home Screen, and several apps makes a hardware or display-assembly problem more plausible, but inspection is still required for confirmation.
Should I factory-reset an iPhone with an unresponsive screen?
A factory reset is not a routine fix for a cracked screen, permanent dead zone, ghost touches, liquid exposure, or display problem after a drop or repair. It erases data and cannot repair damaged hardware. This guide therefore does not include a factory reset or full restore.

How This Guide Was Verified
Last technically checked:
August 2, 2026
Research method:
Current Apple Support and iPhone User Guide pages were opened directly. Page titles, troubleshooting steps, force-restart sequences, accessibility settings, update instructions, repair-history guidance, and clean destination URLs were checked before output.
Physically tested:
No documentation reviewed.
Applies to:
iPhone models with an unresponsive, intermittent, overly sensitive, or partially non-working touchscreen. Button combinations, available settings, and Parts and Service History information vary by iPhone model and iOS version.
Important limitation:
These tests can separate app freezes, accessory interference, accessibility settings, and persistent display symptoms. They cannot confirm a failed digitizer, display connector, logic-board circuit, or other internal component without physical diagnostics.
Data-loss risk:
Conditional. The main troubleshooting steps do not erase data. Back up the iPhone before installing updates or arranging service when the touchscreen works well enough to do so.
Final Steps
- Begin by disconnecting accessories, removing the case and protector, and making sure the screen is clean and dry.
- If the whole screen is frozen, perform the correct force restart. If only one app is affected, troubleshoot that app rather than the entire display.
- A dead area that remains in the same location across multiple apps after a restart is the most useful sign that professional display inspection may be necessary.
- Stop immediately if the screen is lifted, the phone is unusually hot, liquid is present, glass is unsafe, or the device begins registering uncontrolled touches.
