Why Is My Phone Screen Flickering? Causes & Fixes

A flickering phone screen is one of the most frustrating issues smartphone users experience. One moment your display looks perfectly normal, and the next it starts flashing, dimming unexpectedly, or rapidly changing brightness without any input.

Sometimes the problem only appears when you lower the screen brightness. In other cases, the display may flicker constantly, show horizontal lines, flash green, or even become completely unusable.

The good news is that screen flickering doesn’t always mean your phone needs a new display. Many cases are caused by temporary software glitches, problematic apps, outdated operating systems, incorrect display settings, or battery-related power issues. However, if the flickering started after dropping the phone, exposing it to water, or following a strong impact, the issue could involve damaged display components or internal hardware.

Understanding the real cause is important because applying the wrong fix may waste time or even make the problem worse.

In this guide, we’ll explain:

• Why phone screens flicker
• How to identify whether it’s a software or hardware issue
• Step-by-step troubleshooting methods
• When professional repair is the best solution
• How iExpert Repairs helps customers across the UK restore damaged smartphone displays quickly and safely

Quick Answer

If your phone screen is flickering, the most common causes include:

• Software bugs after an update
• Display settings or adaptive brightness problems
• Faulty third-party apps
• OLED display behaviour at low brightness
• Battery or power management issues
• Loose display connectors
• Physical screen damage
• Water damage
• Faulty display hardware

If the flickering only started recently, basic troubleshooting such as restarting the phone, updating the operating system, or removing a problematic app may solve the issue. However, if your screen continues flickering after a drop or liquid exposure, professional diagnosis is usually required.

Warning Signs You Shouldn’t Ignore

Although many cases of screen flickering are caused by software issues, some symptoms can indicate a more serious hardware fault that requires immediate attention. Ignoring these warning signs may lead to further damage or complete display failure.

If you notice any of the following, it’s best to stop troubleshooting and arrange a professional inspection:

• The screen started flickering after your phone was dropped.
• Green, white, or purple lines appear on the display.
• The touchscreen has become slow or unresponsive.
• The screen randomly turns black before coming back on.
• Flickering becomes more frequent or severe over time.
• Your phone has recently been exposed to water or moisture.

Backing up your important data as soon as possible is also recommended, especially if the display is becoming increasingly unstable.

Introduction

A flickering phone screen can be frustrating, making it difficult to use your device for everyday tasks such as messaging, browsing, watching videos, or working. Sometimes the screen flashes occasionally, while in other cases it may constantly blink, dim unexpectedly, show coloured lines, or become completely unreadable. The good news is that screen flickering doesn’t always mean you need a new display. In many cases, the problem is caused by software bugs, faulty apps, incorrect display settings, or temporary system glitches that can be fixed without replacing any parts.

However, if the flickering started after a drop, water exposure, or physical impact, it may indicate a damaged display or internal hardware fault. In this complete UK guide, we’ll explain why your phone screen is flickering, the most common causes, step-by-step fixes you can try at home, and when it’s time to seek professional repair from experienced technicians.

What Does Screen Flickering Actually Mean?

Screen flickering happens when the display refreshes incorrectly or receives unstable signals from either the software or the hardware controlling the screen.

Depending on the underlying cause, flickering may look different from one phone to another.

Some users notice:

• Rapid flashing between bright and dark
• Green or white screen flickering
• Horizontal or vertical lines appearing briefly
• Random brightness changes
• Display flashing while charging
• Screen flickering only when unlocking the phone
• Flickering after installing a software update
• Display blinking during gaming or video playback

Because these symptoms can point to very different problems, it’s important to identify when the flickering occurs rather than focusing only on what it looks like.

Can Screen Flickering Get Worse?

Yes. In many cases, screen flickering starts as a minor inconvenience before developing into a more serious hardware problem. If the underlying cause is a damaged OLED panel, loose display connector, failing battery, or internal motherboard fault, the issue may gradually become worse over time.

Ignoring persistent flickering can sometimes lead to:

• Complete display failure
• Green or purple lines appearing on the screen
• Black spots or dead pixels
• Touchscreen responsiveness issues
• Random black screens
• Difficulty accessing important data

If the flickering continues despite basic troubleshooting or becomes more severe, arranging a professional diagnosis early can often prevent additional damage and reduce repair costs.

What Causes a Phone Screen to Flicker?

There isn’t a single reason why a phone display starts flickering. In our repair experience, the issue usually falls into one of two categories:

• Software-related problems, which can often be fixed at home.
• Hardware-related faults, which usually require professional repair.

Before replacing the screen, it’s worth understanding which category your phone falls into.

Software-Related Causes

Software problems are often temporary and may appear after installing a system update, downloading a faulty app, or changing display settings.

Common software causes include:

1. A Recent Software Update

Operating system updates occasionally introduce display bugs that affect specific phone models. If the flickering started immediately after updating your device, the issue may be software-related rather than physical damage.

This is also why keeping your device updated with future bug-fix releases is important.

2. Faulty or Incompatible Apps

Not every app is fully optimised for every Android version or iOS release.

Some poorly coded applications continuously refresh the display, overload the graphics processor, or conflict with system settings, causing temporary flickering.

If the problem only appears while using one particular app, uninstalling or updating it may resolve the issue.

3. Display Brightness Settings

Modern smartphones automatically adjust brightness using ambient light sensors.

Although this feature improves battery life, incorrect brightness calibration or adaptive brightness bugs may cause noticeable flickering, especially on OLED displays.

Some users only notice the problem at very low brightness levels.

4. Display Driver or GPU Software Errors

The operating system constantly communicates with your display using graphics drivers.

If those drivers become corrupted after an interrupted update or software conflict, your screen may:

• Flash randomly
• Refresh incorrectly
• Blink during animations
• Freeze before flickering

5. Battery Power Management Issues

A weak battery doesn’t only reduce battery life.

When the battery struggles to deliver stable voltage, especially on older devices, the display may begin flickering during heavy use or when the battery percentage becomes very low.

If you’ve also noticed your battery draining unusually quickly, our guide “Why Is My Phone Battery Draining So Fast?” explains how battery health can affect overall phone performance.

Hardware-Related Causes

If software troubleshooting doesn’t solve the problem, the issue may involve physical damage inside the device. These repairs usually require specialist equipment and replacement parts.

1. Physical Impact or Accidental Drops

One of the most common causes we see at iExpert Repairs is accidental impact damage. Even when the front glass appears intact, the OLED panel underneath can develop invisible damage that causes:

• Continuous flickering
• Green lines
• White flashes
• Black patches
• Touchscreen instability

If your display has also become difficult to control, our guide explains how screen damage often affects both the display and touch functionality.

2. Loose Display Connector

Inside every smartphone, delicate ribbon cables connect the display to the motherboard. A heavy drop can partially loosen these connectors without cracking the screen.

Symptoms often include:

• Flickering when moving the phone
• Screen randomly turning black
• Display returning after pressing the frame
• Intermittent flashing

This type of fault requires internal inspection by an experienced technician.

3. Water or Moisture Damage

Liquid exposure doesn’t always stop a phone from working immediately. Moisture can slowly corrode display connectors and internal circuits over time, causing intermittent flickering days or even weeks after contact with water.

If your phone has recently been exposed to rain, spilled drinks, or humidity, it’s worth reading our guide before attempting further troubleshooting.

4. Display Panel Failure

OLED and AMOLED displays contain millions of tiny pixels. As displays age – or after suffering impact damage -these pixels can begin failing, leading to:

• Persistent flickering
• Green tint
• White flashing
• Screen burn
• Dead areas
• Colour distortion

Unfortunately, display panel failure usually cannot be repaired through software and often requires a complete screen replacement.

Is It More Likely to Be a Software Issue or Hardware Damage?

One of the first questions customers ask our technicians is whether screen flickering is something they can fix themselves. Rather than assuming the worst, compare how and when the problem started.

If this sounds familiar…	It’s more likely to be…	A sensible next step
The flickering began after a software update	Software issue	Check for newer updates, restart the device, and install any available bug fixes.
It only happens while using one app	App-related problem	Update or remove the app to see if the issue disappears.
The screen started flickering after being dropped	Hardware damage	Avoid putting pressure on the display and arrange a professional inspection.
Flickering appeared after contact with water	Internal moisture damage	Power off the device if possible and have it checked before corrosion spreads.
The display flickers only at very low brightness	Display settings or OLED behaviour	Test different brightness levels and disable adaptive brightness temporarily.
The screen flashes alongside coloured lines or touch problems	Display or connector fault	Back up your data and book a repair as soon as possible.

The way the issue started often tells you more than the flickering itself. Paying attention to recent updates, accidental drops, or exposure to moisture can save time and help you choose the right solution.

Is It Safe to Keep Using a Flickering Phone?

It depends on what’s causing the problem.

If the flickering is linked to a temporary software glitch or an app conflict, you can usually continue using your phone while working through the troubleshooting steps in this guide.

However, if the flickering started after a drop, liquid exposure, or is accompanied by coloured lines, black spots, or touchscreen problems, continuing to use the device could make the damage worse. In these situations, it’s a good idea to back up your data and have the phone professionally inspected as soon as possible.

Acting early can often prevent a small display issue from turning into a more expensive repair.

How to Fix a Flickering Phone Screen

If your phone screen is flickering, don’t assume the display needs replacing straight away. In our experience at iExpert Repairs, many flickering issues are resolved with a few simple troubleshooting steps – especially when the problem is software-related.

Work through the following solutions in order. After each step, use your phone for a few minutes to see whether the flickering has stopped before moving on.

1. Restart Your Phone

It may sound obvious, but restarting your phone is often the quickest way to clear temporary software glitches affecting the display.

During normal use, background processes, apps, and system services can become unstable. A restart refreshes these processes and may restore normal screen behaviour.

To restart your phone:

Android

• Hold the Power button.
• Tap Restart.
• Wait for the phone to reboot.

iPhone

• Press and hold the Side button with either Volume button.
• Slide to power off.
• Turn the device back on after 30 seconds.

If the flickering disappears after restarting but returns later, the cause is likely software rather than hardware.

2. Check for Software Updates

Manufacturers regularly release updates that fix display bugs, graphics driver issues, and compatibility problems. If your screen started flickering shortly after a recent update, it’s worth checking whether a newer patch has already been released.

Android

Go to:

Settings → Software Update → Download and Install

iPhone

Go to:

Settings → General → Software Update

Install any available updates before continuing with further troubleshooting.

3. Restart in Safe Mode (Android)

Safe Mode temporarily disables third-party apps. If your phone stops flickering in Safe Mode, one of your installed apps is almost certainly causing the problem.

Common offenders include:

• Screen filter apps
• Battery-saving applications
• Custom launchers
• Display enhancement apps
• Game optimisation tools

Remove recently installed apps one at a time until the issue disappears.

4. Remove Recently Installed Apps

Think back to when the flickering first started. Ask yourself:

• Did I install a new app?
• Did I download an APK?
• Did I install a game?
• Did I add a battery optimisation app?
• Did I install a screen recorder?

If the answer is yes, uninstall the newest app first. Many display problems begin after installing poorly optimised software rather than because of hardware failure.

5. Turn Off Adaptive Brightness

Adaptive Brightness constantly changes screen brightness based on surrounding light. Although useful, it occasionally causes flickering on OLED displays.

Try disabling it temporarily.

Android

Settings → Display → Adaptive Brightness → Off

iPhone

Settings → Accessibility → Display & Text Size

Turn off Auto-Brightness. Use the phone for a while afterwards. If the flickering disappears, you’ve likely identified the cause.

6. Increase Screen Brightness

Many OLED and AMOLED displays naturally use Pulse Width Modulation (PWM) to control brightness. Some users notice flickering only when brightness is set very low.

Try increasing brightness to around 60-80%.

If the flickering disappears at higher brightness but returns at lower levels, the behaviour may be linked to OLED dimming rather than a damaged display. However, if the flickering becomes more severe over time, professional inspection is still recommended.

7. Let Your Phone Cool Down

Overheating affects more than just battery performance. Excessive heat can temporarily reduce display stability, causing:

• Brightness fluctuations
• Random flashing
• Display lag
• Temporary flickering

Allow the phone to cool naturally.

Avoid:

• Direct sunlight
• Wireless charging while gaming
• Heavy gaming sessions
• Charging under pillows or blankets

8. Check Whether Flickering Happens While Charging

Some users notice screen flickering only when the charger is connected. This can happen because of:

• A damaged charging cable
• A faulty charger
• Poor-quality third-party accessories
• Charging port damage
• Battery voltage instability

Try using:

• The original charger
• A different charging cable
• Another wall adapter

9. Look for Signs of Physical Damage

Even a small drop can damage the display beneath the outer glass.

Carefully inspect your phone for:

• Hairline cracks
• Bent corners
• Green lines
• Purple patches
• Black spots
• Loose screen edges
• Flickering when pressure is applied

If you notice any of these symptoms, the issue is unlikely to be solved with software troubleshooting.

10. Back Up Your Data Before the Screen Gets Worse

If the display is becoming increasingly unstable, don’t wait until it stops working altogether.

Back up:

• Photos
• Videos
• Contacts
• Documents
• Messages
• Authentication apps

A display that flickers today may become completely black tomorrow. Protecting your data early can prevent unnecessary stress later.

Device-Specific Fixes

Although screen flickering affects every smartphone brand, the underlying causes can vary depending on the device. Here are a few brand-specific checks worth trying.

1. iPhone Screen Flickering

Recent iPhone models use advanced OLED displays that occasionally experience software-related display bugs after iOS updates. Try the following:

• Install the latest version of iOS.
• Disable Auto-Brightness temporarily.
• Turn off Reduce White Point (if enabled).
• Restart the device.
• Check whether the flickering started after a recent drop.

If Face ID, touch response, or brightness control also behave unusually, the display assembly may have been damaged.

Our iPhone Repairs service covers screen replacements, display diagnostics, battery repairs, charging issues, and water damage using premium-quality replacement parts.

2. Samsung Screen Flickering

Samsung Galaxy devices often use AMOLED displays. Flickering may occur because of:

• Adaptive Brightness
• High refresh rate conflicts
• Software bugs
• OLED ageing
• Impact damage

Try:

• Switching from 120Hz to 60Hz temporarily.
• Updating One UI.
• Restarting in Safe Mode.
• Removing recently installed apps.

If green lines appear alongside flickering, professional diagnosis is strongly recommended.

Our Samsung Repairs service includes genuine-quality display replacements, battery repairs, charging port repairs, and motherboard diagnostics.

3. Google Pixel Screen Flickering

Google Pixel phones occasionally experience display issues after Android updates.

Start by:

• Installing all available updates.
• Restarting the phone.
• Testing Safe Mode.
• Turning Adaptive Brightness off.
• Checking whether the issue only occurs at low brightness.

If the display remains unstable after software troubleshooting, the screen or internal connector may require replacement. Our Google Pixel Repairs team regularly repairs Pixel displays, charging ports, batteries, and water-damaged devices.

4. Huawei Screen Flickering

Huawei devices are generally reliable, but older models may develop display issues caused by ageing components or accidental damage.

Recommended checks include:

• Updating EMUI (if updates are available).
• Restarting the device.
• Removing recently installed apps.
• Testing different brightness levels.

Persistent flickering after a drop or liquid exposure usually indicates hardware damage rather than a software fault.

Our Huawei Phone Repairs service includes screen replacements, battery repairs, charging port repairs, and complete hardware diagnostics.

When Does a Flickering Screen Need Professional Repair?

Not every flickering screen can be fixed at home. If you’ve worked through the troubleshooting steps in this guide and the problem keeps returning, it’s likely that the issue lies inside the phone rather than within its software.

At iExpert Repairs, we regularly diagnose phones that appeared to have a simple display glitch but were actually suffering from internal hardware damage. In many cases, customers delayed getting the device checked, only for the screen to deteriorate further over the following days.

Professional diagnostics become especially important when the flickering is accompanied by other symptoms such as touch issues, coloured lines, black spots, or random screen blackouts.

Common Mistakes That Make Screen Flickering Worse

When trying to fix a flickering phone screen, it’s easy to make mistakes that can worsen the problem. Avoiding these common errors can help protect your device and reduce the risk of more expensive repairs.

Avoid:

• Continuing to use the phone after a significant drop.
• Ignoring signs of water or moisture damage.
• Pressing firmly on the screen to stop the flickering.
• Using low-quality chargers or charging cables.
• Installing unofficial apps or software from untrusted sources.
• Delaying a professional inspection when the flickering becomes more frequent or severe.

If the problem persists after basic troubleshooting, professional diagnosis is usually the safest and most cost-effective solution.

Signs Your Phone Needs Professional Repair

If you notice any of the following, it’s time to stop troubleshooting and arrange a professional inspection.

• The screen continues to flicker after restarting the device.
• Flickering began after the phone was dropped.
• The display flashes green, white, or purple.
• Horizontal or vertical lines have appeared.
• The touchscreen is no longer responding correctly.
• The screen turns black before coming back on.
• Flickering only gets worse over time.
• The phone has been exposed to water or excessive moisture.
• Brightness changes randomly, even after resetting the device.
• The display occasionally goes completely blank.

These symptoms usually indicate a damaged display panel, loose internal connector, battery-related power issue, or motherboard fault.

How iExpert Repairs Diagnoses Screen Flickering

Finding the real cause of screen flickering isn’t as simple as replacing the display.

Our technicians follow a structured diagnostic process to avoid unnecessary repairs and ensure customers only pay for the work their device actually needs.

A typical inspection includes:
