Ghost touch — your phone is tapping itself.
Your phone screen is acting on its own — opening apps, typing random characters, scrolling through menus, or making calls you didn't initiate. This is ghost touch, it's a hardware fault, and it needs attention because it's a genuine security risk.
Immediate step: enable Airplane Mode
Ghost touch can make calls, send messages, and potentially authorise payments without your input. Enable Airplane Mode immediately (swipe down for Control Centre/Quick Settings) to prevent unintended communication while you work out the fix.
What causes ghost touch
Ghost touch happens when the digitiser — the transparent touch-sensing layer built into the screen assembly — sends false touch signals to the processor. The phone genuinely believes someone is touching the screen in locations where no finger exists. There are five common causes:
Cause 1: Cracked screen (most common)
Even a small crack can sever the digitiser's conductive grid, creating false signals where the crack intersects touch-sensing traces. This is by far the most common cause — a phone with a cracked screen that "still works" can develop ghost touch days or weeks after the crack appeared. The fix is screen replacement.
Cause 2: Budget aftermarket screen (post-repair)
Ghost touch after a recent screen replacement usually means a low-quality aftermarket digitiser. Budget screens have lower-tolerance touch layers that produce false inputs, especially near the edges and corners. The fix is having the shop replace the screen with a higher-grade panel. Under Australian Consumer Law, the shop is responsible for this fault regardless of their stated warranty period.
Cause 3: Water or moisture damage
Moisture between the screen layers creates false electrical signals that the digitiser interprets as touch input. This can happen from obvious water exposure (water damage) or from humidity gradually penetrating a cracked screen. The fix is ultrasonic cleaning ($49–$99) and screen replacement if the digitiser is permanently damaged.
Cause 4: Screen protector issues
Air bubbles or moisture trapped under a screen protector can cause intermittent ghost touch, especially on edge-curved screens (Samsung S-series). This is the easiest to diagnose — remove the screen protector and test. If ghost touch stops, the protector was the cause. Reapply a new protector carefully, or use a flat-edge protector on curved screens.
Cause 5: Loose display connector
A drop impact can partially dislodge the display flex cable from the logic board connector. The digitiser still works but sends intermittent false signals. A technician can reseat the connector in 10–15 minutes — often free or $20–$39 diagnostic fee. This is the cheapest possible fix if it applies.
Try these before paying for a repair
Remove the screen protector. If you have one, peel it off and use the phone for 10 minutes without it. If ghost touch stops, the protector was trapping moisture or air. This is a free fix.
Clean the screen thoroughly. Oils, sweat, and moisture on the screen surface can occasionally cause false touches. Clean with a microfibre cloth and test. This rarely fixes true ghost touch but it's worth eliminating.
Restart the phone. In rare cases, a software glitch can mimic ghost touch (a stuck process sending touch events). A force restart clears this. If ghost touch returns after restart, it's hardware.
Boot into Safe Mode. On Android: hold Power, long-press "Power Off" to get Safe Mode option. On iPhone: there's no user-accessible safe mode, but a force restart serves a similar purpose. If ghost touch disappears in Safe Mode, a rogue app may be the cause — uninstall recently added apps.
What the repair costs
If ghost touch is caused by the screen (causes 1, 2, or 3 above), the fix is a full screen replacement. You can't repair just the digitiser — it's fused to the display panel as a single assembly on all modern phones.
Screen replacement costs vary by model — $109–$619 AUD at independent shops. For your specific model, use the repair calculator.
If it's a loose connector (cause 5), the fix is much cheaper — typically $0–$39 for a diagnostic and reseat. A good shop will check the connector before recommending a full screen replacement.
If ghost touch appeared after a recent repair: The shop that did the repair is responsible under Australian Consumer Law. Go back to them first. If they used a budget screen that's causing the ghost touch, they need to replace it with a working part at no additional cost. See our consumer rights guide.
Why you shouldn't ignore ghost touch
Security risk: A phone making calls, sending messages, or opening apps on its own can expose personal information, trigger unwanted purchases, or send embarrassing messages to contacts. If the phone has banking apps installed, ghost touch could theoretically interact with them.
It gets worse: Ghost touch from a cracked screen worsens as the crack spreads. Ghost touch from moisture damage worsens as corrosion progresses. The sooner you address it, the cheaper the fix — a screen-only repair today could become a screen + board repair next month.
It drains battery: Constant false touch inputs keep the screen awake and the processor active, significantly increasing battery drain. If your battery is dying faster than usual AND you have ghost touch, the two are related.
