How to Fix an iPhone Touch Screen Not Responding on One Side
An iPhone display that responds on one side but ignores taps on the other can make ordinary tasks surprisingly difficult. You may be unable to type certain letters, swipe through a page, open Control Centre, or answer a call because the affected area sits along the edge of the screen. The cause might be a temporary software fault, a dirty display, a faulty screen protector, moisture, or physical damage to the touch layer.
Start with the simplest checks before assuming the screen needs replacing. A restart, careful cleaning, and removing accessories can resolve intermittent touch problems. If the same region remains unresponsive after those steps, treat the issue as a possible hardware fault and avoid actions that could make the damage worse.
Check Whether the Problem Is Temporary
First, remove anything that may interfere with the display. Take off the case and screen protector, particularly if the protector is cracked, lifting at an edge, or fitted with dust underneath. Wipe the screen with a soft, dry, lint-free cloth. Do not spray cleaner directly onto the iPhone, and avoid pressing hard over the unresponsive area.
Disconnect all charging cables and accessories, then test the display again. A damaged or poor-quality cable, power adapter, or USB accessory can sometimes cause erratic touch behaviour while connected. If the problem occurs only during charging, use an Apple-certified or reputable cable and adapter and inspect them for fraying or bent connectors.
A wet screen can also register touches incorrectly. Dry both the display and your hands, and allow the phone to return to room temperature if it has been exposed to condensation. An iPhone that has been splashed should not be dried with a hairdryer, placed in rice, or repeatedly connected to a charger while moisture may remain inside.
Restart and Update the iPhone
A normal restart clears temporary system processes that may be affecting touch input. On an iPhone with Face ID, hold the side button and either volume button until the power-off slider appears. On models with a Home button, hold the side or top button instead. Slide to power off, wait around 30 seconds, and turn the phone on again.
If the display prevents you from dragging the slider, use a force restart. On most recent iPhones, press and quickly release volume up, press and quickly release volume down, then hold the side button until the Apple logo appears. The sequence differs on some older models, so avoid holding several buttons at random, as this may trigger other functions such as Emergency SOS.
Once the phone is working, install any available iOS update through Settings > General > Software Update. Updates can correct touch-related bugs affecting a particular iPhone model or app. Before updating, connect to Wi-Fi and create an iCloud or computer backup if the device is usable. If the problem began immediately after an update, record the iOS version and check whether touch fails across the whole system or only in one app.
Test the Display Across Different Apps
A useful test is to open several apps and deliberately touch different parts of the screen. Try Settings, Safari, Messages, the keyboard, and a drawing or markup tool. If the same strip or corner fails everywhere, the problem is more likely to involve the display’s digitiser, which is the layer that detects touch.
If touch works in Settings but fails in one app, close and reopen that app, update it through the App Store, or remove and reinstall it if your data is safely stored. Some apps can appear frozen, especially after a network failure or an incomplete update. A single app problem does not usually indicate that the physical screen is defective.
The keyboard provides a practical way to map the affected area. Type across every row, rotate the phone, and try both portrait and landscape orientation. If the unresponsive portion changes with orientation, software or an app layout issue is possible. If the same physical section of glass remains inactive after rotation, hardware becomes more likely.
AssistiveTouch can provide temporary access to controls when taps are difficult. Go to Settings > Accessibility > Touch > AssistiveTouch and enable it, if you can navigate the menus. You can also connect a Bluetooth keyboard or use a computer for backup in some situations. These are workarounds, not repairs, so continue testing before relying on them.
Look for Physical or Environmental Damage
A recent drop, impact, bend, or pressure event is a strong clue. The glass may look intact while the underlying touch sensor, display connector, or internal frame has been damaged. A screen that began failing after being sat on, squeezed in a bag, or dropped onto a hard surface should be handled as a hardware issue, even if only one side is affected.
A replacement screen can create similar symptoms when it is poorly fitted, damaged during installation, or incompatible with the phone. This is especially relevant after a low-cost repair. Keep the repair receipt and ask the provider to test the entire touch area rather than simply replacing the protector. A loose connector may produce intermittent faults, but opening the iPhone yourself can introduce further damage.
Heat and cold can temporarily affect performance. Do not test a very hot iPhone in direct summer sun in Perth or Brisbane, and do not place a cold phone on a heater to warm it quickly. Let it return gradually to a normal indoor temperature. If the display is lifting away from the frame, stop pressing it and stop charging the device, because a swollen battery may be pushing the screen outward.
If the phone has suffered liquid exposure, arrange professional assessment promptly. Water resistance is not permanent and does not cover every situation, including salt water, pool chemicals, or a damaged seal. In Australia, beach trips around Sydney, Melbourne, or the Gold Coast can expose a phone to fine sand and moisture that enter around a damaged edge.
Reset Settings Before Erasing Data
When the screen fault appears software-related, resetting all settings can be worth trying. This does not delete photos, messages, apps, or other personal files, but it does restore preferences such as Wi-Fi networks, keyboard settings, privacy permissions, and some accessibility options. Find it under Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings.
Before doing this, check whether features such as Touch Accommodations, Zoom, VoiceOver, or Switch Control have been enabled accidentally. These options alter how taps, swipes, and held touches are interpreted. Go to Settings > Accessibility and review the relevant settings. A change to touch duration or gesture behaviour can feel like a dead area when the screen is actually detecting input differently.
Back up the iPhone before taking more serious steps. iCloud backup is convenient over a reliable Australian home or mobile connection, while a Mac or Windows computer can create a local backup. If you use a limited mobile data plan or are travelling through regional areas, wait for stable Wi-Fi rather than interrupting a backup halfway through.
A full erase may fix corrupted system data, but it should be a last software step. Confirm that your photos, contacts, authenticator codes, passwords, and app data are backed up first. If the touch fault remains on the setup screen after an erase, that is strong evidence of a hardware problem rather than an app or user setting.
Decide Between Repair and Replacement
Contact Apple, an Apple Authorised Service Provider, or a reputable independent repairer when one side remains unresponsive after cleaning, restarting, updating, and testing in several apps. Explain when the problem began, whether the phone was dropped or wet, and whether a screen or battery was recently replaced. A clear history helps the technician avoid repeating basic tests.
Apple’s limited warranty generally covers manufacturing defects but does not cover accidental damage. Australian consumers also have protections under the Australian Consumer Law, which can apply when a product is not of acceptable quality, fit for purpose, or durable for a reasonable period. Your rights depend on the circumstances, including the phone’s age, price, fault, and cause. Keep proof of purchase and ask for a written assessment.
The cheapest screen replacement is not always the best value. Ask whether the part is genuine or aftermarket, whether Face ID and display features will be tested, what warranty covers the repair, and whether important data could be affected. A repairer should explain the price before proceeding. If the iPhone is older and also has poor battery health, compare the total repair cost with the price of a reliable replacement.

| What you observe | Likely direction | Sensible next step |
|---|---|---|
| Touch fails only while charging | Cable, adapter, interference, or moisture | Disconnect accessories, dry the phone, and test with a trusted charger |
| One area fails in every app | Digitiser or display hardware | Back up data and arrange professional diagnosis |
| The issue started after a drop | Physical screen or connector damage | Avoid pressing the panel and seek a repair assessment |
| Touch works after removing the protector | Protector fit, crack, or trapped debris | Replace the protector with a correctly fitted one |
| The problem affects one app only | App bug or corrupted app data | Update, close, or reinstall the affected app |
| Touch fails after liquid exposure | Internal moisture or corrosion | Power down where possible and seek urgent inspection |
| The phone works after a restart but fails again | Software instability or developing hardware fault | Update iOS, back up, and monitor for recurrence |
If only one side of your iPhone touch screen is unresponsive, begin with low-risk checks and record what changes. Remove the case and protector, dry the device, disconnect accessories, restart it, test multiple apps, and back up your data. Persistent failure in the same physical area deserves professional attention, particularly after a drop, liquid exposure, or previous repair. Acting early can protect your data and make it easier to pursue a suitable repair or Australian Consumer Law remedy.
