iPhone Touch Screen Not Working? Here’s Why (And What To Check)
Your iPhone touch screen isn’t working. Maybe touch doesn’t respond at all. Maybe part of the screen doesn’t respond. Maybe it stopped working after a screen replacement or a drop. Maybe you’re getting ghost touches, or the response is delayed. Or maybe the screen is black but touch still works.
The good news is that most touch faults are diagnosable without specialist tools. And in some cases, the fix is free — a screen protector, a software restart, or a reseated connector.
The key is working out whether the fault is the display assembly, the display flex, or a setting. The symptom tells you where to look.
This page covers the eight most common touch fault patterns, the symptoms to look for, and the checks you can perform yourself. If you need the complete diagnostic sequence for determining whether the fault is the digitizer, the display flex, the touch IC, or a setting, the full guide is linked at the bottom.
Quick Diagnosis
Touch not responding at all: a display flex fault, a digitizer fault, or a software freeze.
Touch not responding in some areas: a digitizer dead zone or a damaged display flex.
Touch not responding after a screen replacement: a loose connector, damaged flex, or non-genuine display.
Touch not responding after a drop: a damaged display assembly.
Ghost touches: a failing digitizer or a cheap screen protector.
Delayed touch response: heavy CPU load, full storage, or a failing digitizer.
Touch works intermittently: a loose display connector or a partially damaged flex.
Touch works but the display doesn’t: a failed display panel with an intact digitizer.
Why Your iPhone Touch Screen Stops Working
An iPhone touchscreen has several layers:
The digitizer registers touch input
The touch IC processes the signal and sends it to the logic board
The display panel shows the image
The display flex carries both the touch signal and the display signal
If any link fails, the touchscreen may not respond, may respond incorrectly, or may show a black screen while still registering touch.
Common Causes
Failed display flex. The most common cause. The flex cable carries touch signals, and when it fails, touch stops.
Failed digitizer. The touch layer in the display assembly has failed.
Failed touch IC. The touch IC on the logic board has failed. This is rare.
Screen protector interference. A cheap or poorly fitted protector.
Software freeze. iOS has frozen and isn’t responding.
Debris under the screen. Particles pressing on the digitizer.
Damage from a drop. The impact has damaged the display assembly.
Damage from a previous repair. A loose connector or damaged flex.
Symptoms To Look For
The symptom tells you which component is at fault.
Touch Not Responding At All
Display flex, digitizer, or a software freeze.
Touch Not Responding In Some Areas
Digitizer dead zone or damaged display flex.
Touch Not Responding After a Screen Replacement
Loose connector, damaged flex, or non-genuine display.
Touch Not Responding After a Drop
Damaged display assembly.
Ghost Touches
Failing digitizer or a cheap screen protector.
Delayed Touch Response
Heavy CPU load, full storage, or a failing digitizer.
Touch Works Intermittently
Loose display connector or partially damaged flex.
Touch Works But the Display Doesn’t
Failed display panel with an intact digitizer.
How to Diagnose the Fault
Step 1 — Try a Forced Restart
On iPhone 8 and later: press volume up, press volume down, then hold the side button until the Apple logo appears.
On iPhone 7: hold volume down and the side button.
On iPhone 6s and earlier: hold home and the side button.
Step 2 — Remove Any Screen Protector
A cheap or poorly fitted protector is a common cause of touch faults. Remove it, clean the screen, and test.
Step 3 — Clean the Screen
Oil, dirt, or moisture can affect touch sensitivity.
Step 4 — Check Touch Settings
Settings, Accessibility, Touch. Turn off Touch Accommodations and AssistiveTouch if they’re enabled.
Step 5 — Try Touch in Different Areas
Map out exactly where touch works and where it doesn’t. This tells you whether the fault is a dead zone or a full failure.
Step 6 — Close Background Apps and Check Storage
Settings, General, iPhone Storage. Free up space if the phone is full.
Step 7 — Open the Phone and Reseat the Display Connectors
If the fault persists, the display connectors may be loose. Reseating them often fixes intermittent touch faults.
Step 8 — Try a Known-Good Display
If you have access to a known-good display, test with it. If the known-good display works, the original display has failed.
Fixing Specific Touch Faults
iPhone Touch Screen Not Working
The general fault. Check the protector first, then try a forced restart. If neither fixes it, the display assembly has failed.
iPhone Touch Screen Not Responding
Same fault, different phrasing. Check the protector and try a restart.
iPhone Touch Screen Not Working After Replacement
A loose connector, a damaged flex, or a non-genuine display. Reseat the connectors and test.
iPhone Touch Screen Not Working After Drop
The impact has damaged the display assembly. Replacement is the fix.
iPhone Ghost Touches
A failing digitizer or a cheap screen protector. Remove the protector first, then unplug the charger as a test.
iPhone Touch Screen Delayed
Heavy CPU load or full storage. Close background apps and free up space.
iPhone Touch Screen Intermittent
A loose display connector or a partially damaged flex. Reseating often fixes it.
iPhone Screen Black But Touch Works
The display panel has failed, but the digitizer is intact.
iPhone 11 Screen Not Working
The diagnostic sequence is the same across models. Check the protector first.
iPhone 13 Touch Screen Not Working
Same sequence. The 13 has similar touch characteristics to the 12.
iPhone XR Screen Issues
The XR uses an LCD display. The diagnostic logic is the same as OLED models.
Repair Cost Guide
Display replacement: $60 to $300 for the part, $100 to $400 fitted.
Touch IC repair: $100 to $200 fitted.
Screen protector: $5 to $20.
When to Repair vs Bin
Repair if:
The fault is the display assembly or the display flex
The phone is under four years old
The repair cost is under half the cost of a comparable new phone
The phone has no other faults
Bin if:
The touch IC has failed on a phone over five years old
The phone has multiple failed components
The repair cost exceeds half the cost of a comparable new phone
Safety Warning
Electrical risk. Lithium batteries are a fire risk if punctured, bent, or crushed. Do not attempt to remove a swollen battery.
Display risk. The display flex cables are thin and fragile. Prying the display at the wrong angle tears them.
Tool risk. Never use metal tools against a display or display flex.
Screw risk. iPhone screws are different lengths. Putting a long screw in a short hole punches through the logic board.
