Hardware Problems Behind Flickering Display
A flickering phone screen can certainly be maddening. But don’t lose your cool just yet – hardware issues could be the real culprit. Let’s break it down and fix it.
Physical defects in the display components often cause flickering. Ribbon cables connecting the screen can work loose or get damaged, interrupting signal transfer. Inspect carefully for frayed/kinked cables and reseat connections.
Connector pins can also get bent or corroded over time, resulting in an unstable connection. Check for debris buildup too. Clean and straighten pins, firmly reseat cables.
The OLED display itself will degrade, with pixel burnout leading to flickering issues. If the digitizer is damaged, it could disrupt the image. Screen replacement is the fix for these problems.
Checking Display Cabling
Loose display cables are a common cause of flickering. Carefully inspect connections for any damage or wear.
Look for frayed/kinked cables, corroded/bent pins, gaps in fittings. Reseat cables properly and securely, clean away any debris.
Consider display cable replacement if connections check out ok – the cables still could be intermittently failing.
Examining the Physical Display
With prolonged use, OLED display pixels eventually burn out – this causes a flickering or dithered appearance.
Press firmly on display to check for inconsistencies in colors and digitizer responsiveness. Dead pixels indicate a failing display.
If display damage found, replacement of the screen assembly is required. An experienced repair tech can properly source and install the new component.
Ruling Out Other Hardware
While the display is the most likely culprit, other hardware could potentially contribute to flickering issues.
Faulty RAM or GPU processing can manifest as display problems. Replacing these internal components requires disassembly and soldering skills.

We’ve all been there. You’re minding your own business, texting a friend or scrolling through your social feeds, when suddenly your phone screen starts flickering like a strobe light. Annoying, right? Screen flickering or flashing is usually a software issue, but in some cases it can indicate a problem with the screen itself or other hardware components. Let’s break down the most common causes of a flickering display and how you can stop the madness.
Faulty App Triggering Flickering Screen
One of the most common triggers for a flickering display is a rogue app. Apps run in the background even when you’re not using them directly. If there’s a software glitch or the app wasn’t coded properly, it can start interfering with the screen refresh rate causing flickering or flashing. Force quitting apps and clearing the app cache can sometimes fix the problem. Also make sure your apps are all updated to the latest version which may contain bug fixes.
Certain apps that activate the camera flash like the flashlight, camera, or Snapchat can also cause weird screen issues. The quick on/off of the LED light can play tricks on your eyes and make the display appear to flicker. Just close these apps to get back to normal. Messing around with display brightness settings has also been known to cause flickering with some sensitive screens or older phones. Resetting the brightness back to automatic can help in this scenario.
If the flickering only seems to happen within a particular app, delete and reinstall the app. This gives you a clean slate for the app files and data which may resolve any corrupt files causing conflicts. Check app reviews too – if others are experiencing problems, it’s likely a wider issue on the developer’s end.
Update Software and Firmware
Another common source of display problems is an outdated software or firmware version. Manufacturers release updates to fix bugs, including any issues that may be affecting the screen display. Make sure your iPhone, Android or other device has the latest updates installed. On iPhones, check for an iOS update in Settings > General > Software Update. For Androids, tap Settings > System > Advanced > System Update to update Android OS and security patches.
Carriers will also periodically release firmware updates with fixes for device issues that you can install through the Settings menu. Keeping your software totally up-to-date minimizes the chances of glitchy display problems.
Check Display Settings
Diving into your display settings can help troubleshoot screen flickering in some cases. Things to check include:
- Adjust screen brightness – Some screens flicker on low brightness or when set to auto-brightness.
- Disable auto-rotate – The motion of rotating the screen as you move your phone can appear as flickering.
- Turn off Night Shift/Blue Light filter – These color tinting features may interact oddly with some screens.
- Disable animations – Reducing motion effects like animated scrolling can minimize flickering.
- Change screen timeout delay – Short timeout delays can cause intermittent black flickering.
Toggling these display-related settings off and on again may hit just the right combo to stop the annoyance of a flickering screen.
Check for Physical Damage
While software issues are the main culprit, screen damage can also result in some strange visual artifacts like flickering. Check for any cracked glass, distorted imagery, or unresponsive spots on the screen. Physical screen damage often progresses over time leading to odd screen behavior.
If your phone took a recent tumble, the impact could have damaged connectors between screen components even if glass isn’t actually cracked. You’ll likely need professional repair services for any hardware-related screen flickering issues.
Reset All Settings
If you can’t isolate the issue to a particular app or setting, try resetting all device settings as a last resort troubleshooting step before seeking repair. On an iPhone, go to Settings > General > Reset > Reset All Settings. For Android, tap Settings > System > Advanced > Reset Options > Reset Settings. This will wipe device preferences and restore defaults without erasing personal data.
Hopefully with this reset, any software gremlins causing screen flickering will be banished for good and you’ll be back to normal. Just be prepared to reconfigure your settings after the reset.

Dealing with an annoying flickering phone screen? Before you panic and rush to the repair shop, there are some easy settings tweaks you can try right from your device to potentially stop the flickering for good.
Checking Phone Settings to Prevent Flickering
Screen flickering is usually caused by software conflicts rather than hardware issues. With a few adjustments under the hood, you may be able to override whatever glitch is causing the problem without any major troubleshooting. Here are some display and system settings worth checking and adjusting to prevent screen flickering:
Reduce Animations
All those fun slide, fade and zoom effects when opening apps or navigating menus might be entertaining, but too much animation can overwhelm your device’s graphics processor. To find the animation settings on an iPhone, go to Settings > Accessibility > Motion and turn off anything labeled “Auto-play animations.” On Android, look in Settings > Accessibility > Remove animations. Scaling back on fancy transitions can optimize performance and visualization.
Disable Auto-Brightness
Your phone screens uses ambient light sensors to automatically adjust screen brightness to match your surroundings. Rapidly fluctuating light levels can sometimes confuse the sensor causing the auto-brightness algorithm to go haywire. This can manifest as a flickering effect. Switch your phone to use manual brightness mode instead for consistent illumination.
Lower Refresh Rate
The screen refresh rate determines how many times per second the display image refreshes. Higher rates make motion look smoother but use more resources. Lower refresh rates require less graphics power. If your phone display supports adjusting the refresh rate (common on gaming phones or high-end models), lowering it from 60Hz to 30Hz could potentially resolve a flickering issue.
Toggle Night Shift/Blue Light Filter
Many phones now have a “night mode” that tints the screen amber to reduce eye strain and help you sleep better at night. However, this color filter has been known to interact oddly with screen flickering on some devices. Turn off the blue light filter temporarily to see if it makes a difference.
Update Display Drivers
Like any computer hardware, phones rely on software drivers to operate screen and graphics components. Display driver updates fine tune performance and fix vulnerabilities. On Android, search “update display drivers” to find any available updates for your specific phone model. For iPhones, driver updates roll out via iOS updates.
Change Screen Timeout
To save battery, your screen turns off after a certain duration of inactivity. But if this timeout period is too short, it can create a subtle flickering effect with the display constantly waking and sleeping again. Try increasing the screen timeout delay to at least 30 seconds to minimize black flickering.
Turn Off Lift to Wake
On some phones, merely picking up or tilting the device triggers the screen to turn on in anticipation of use. But the motion sensors can misfire causing the display to rapidly cycle on and off. Disable lift to wake, tap to wake and other motion-activated screen settings if glitchy.
Factory Reset
If all else fails, a factory reset erases all device settings and data to restore your phone to like-new condition. You’ll lose everything, but this clean slate approach resolves many system-level software issues. Back up your phone first before resetting then restore your must-have apps and data.
When to Call for Service
Messing around with settings to stop screen flickering is a logical first step for troubleshooting. But if adjusting animations, brightness, timeouts and other display factors doesn’t cure the problem, underlying hardware problems may be to blame.

Dealing with an annoying flickering, flashing or blinking phone screen? Booting into safe mode can help isolate whether a third party app is to blame for the issues.
Testing in Safe Mode to Isolate Cause
When a phone screen is flickering or flashing inconsistently, apps running in the background are a common culprit. Safe mode loads a minimal version of the operating system without launching third party apps.
If the display issues disappear when booted in safe mode, you can pinpoint troublesome apps causing conflicts and glitches. If problems remain, hardware or core software are likely at fault.
Enter Safe Mode on Android
To enable safe mode on Android devices:
- Press and hold the power button to turn off your phone
- Once powered back on, press and hold the power button again
- Tap and hold the Power Off option that pops up
- “Safe mode” should appear in the lower left corner
On Samsung Galaxy phones, you can also press and hold the Power button and tap Safe Mode to directly restart into it.
Using Your Phone in Safe Mode
With third party apps disabled, use your phone to see if the flickering or flashing screen issue goes away in safe mode.
Try adjusting brightness, opening native apps like Settings and Camera, scrolling webpages, and other actions that previously caused glitches. Take note if the display works normally without any flickering.
Exit Safe Mode
To exit safe mode on Android, press and hold the power button and tap Restart. This will reload the operating system as normal and re-enable all installed apps.
If the screen flickering returns once third party apps load again, you can isolate which problematic app is causing conflict.

If a particular third party app exhibits flickering or strange visuals, delete it and install a fresh copy from the Google Play store. Corrupted or outdated app files could be clashing with system graphics and display drivers.
Be sure to also update all apps in case bug fixes have been released. Review app permissions as well in case improper access is causing conflicts.
If Flickering Persists in Safe Mode
If your phone’s screen continues to flicker and flash even when booted in safe mode, the culprit is likely a core system issue rather than apps.
Potential causes include:
- Outdated or buggy operating system
- Faulty graphics driver
- Corrupted system files
- Physical display damage
If third party apps have been ruled out through testing in safe mode, next steps are updating your operating system and firmware, refreshing your screen, and checking for any visible screen defects requiring hardware repair.
Using Safe Mode on iPhone
iOS does not have an official safe mode, but you can simulate its function by selectively disabling apps.
To troubleshoot, force quit any suspect apps from the app switcher. Then power cycle your iPhone and only launch Apple’s native apps to test if issues remain.
If third party apps seem to cause the flickering, delete and reinstall fresh copies from the App Store. Also update your iOS version in case Apple applied fixes.
When to Throw in the Towel
If you’ve tested in safe mode, updated software, toggled settings, checked for damage, and done other troubleshooting with no relief from flickering issues, it may be time to replace your aging phone.
Upgrading to a newer model can make sense if:

- Repair costs exceed replacement
- Performance is slow and battery life is short
- Your OS is outdated and unsupported
With a new phone, you’ll benefit from optimized software, powerful graphics capability and sturdy Gorilla Glass displays to prevent frustrating flickering.
Is your phone’s display constantly flickering, flashing or blinking? Before paying for expensive component repairs, inspect your device for any physical damage contributing to the issues.
Checking for Hardware Damage or Defects
While glitchy software is the most common cause of an erratic phone screen, physical defects can also result in a bothersome flickering or flashing display. Visually inspect your device to rule out hardware issues before pursuing complex software troubleshooting.
Screen Cracks
Carefully examine the glass front of your phone for any cracks, chips or fractures. Even hairline cracks in the glass can disrupt connections to the digitizer and LCD display underneath, resulting in flickering or dead zones.
Cracked screens tend to get progressively worse over time. Visible screen damage requires replacement of the glass or entire display assembly in most cases.
Backlight Bleeding
LCD displays use LED backlights to illuminate the screen. If the backlight is damaged, it can cause uneven lighting and dark spots – contributing to a flickering effect.
Inspect around the edges and corners of the display for any backlight bleed or clouding. Excessive pressure on the screen can sometimes damage backlights as well.
Discoloration or Dead Pixels
Carefully scan the display for any unusual discolored patches, lines or pixels. One-off dead pixels may not be very noticeable, but clusters of dead or stuck pixels can cause screen distortions.
Use a magnifying glass under bright light for closer inspection. Tap the screen firmly (not too hard!) to see if stuck pixels come back to life.
Touchscreen Responsiveness
Try dragging your finger very slowly across the entire display area to check for any unresponsive spots. If the touch digitizer is damaged, it can manifest as flickering or flashing lines on the screen.
Also try using a stylus to precisely poke at different points on the screen while watching for any glitching response.
Bezel Damage
Inspect the plastic or metal frame extending beyond the glass display. If the bezels are dented, bent or cracked, it can put damaging pressure on internal connections to the screen resulting in artifacts or flickering.
Repair Options for Hardware Damage
If physical defects are contributing to your flickering screen issues, you’ll need professional repair service to replace damaged components and restore normal functionality.
Typical costs for common smartphone screen repairs:
- Glass replacement – $80-$200+
