Why Does Your Phone Keep Blinking?

Before attempting any fixes, it’s important to understand why your phone screen is flickering. The issue can stem from multiple causes, including:

1. Software Glitches

A corrupted app or operating system bug can cause display issues.
Incompatible software updates may interfere with screen performance.
Background processes overloading the GPU can lead to flickering.

2. Hardware Problems

A loose or damaged display connector inside the phone.
A failing screen due to aging or physical damage.
Issues with the graphics processing unit (GPU).

3. External Factors

Exposure to extreme temperatures (hot or cold).
Magnetic interference from accessories or nearby electronics.
Moisture or liquid damage affecting internal components.

Identifying the root cause will help determine whether you can fix the issue yourself or if professional repair is necessary.

How to Fix a Flickering Phone Screen

Depending on the cause, you can try several troubleshooting methods to resolve the flickering issue.

1. Restart Your Phone

A simple restart can often fix temporary software glitches.

Hold the power button and select Restart (or force restart if unresponsive).
For iPhones: Press and release Volume Up, then Volume Down, then hold the Side Button until the Apple logo appears.

2. Check for Software Updates

Outdated software can cause display issues.

Android: Go to Settings > Software Update.
iPhone: Go to Settings > General > Software Update.

3. Disable Auto-Brightness & Refresh Rate Adjustments

Some phones flicker due to adaptive brightness or variable refresh rates.

Turn off Auto-Brightness in display settings.
Set a fixed refresh rate (e.g., 60Hz instead of 120Hz).

4. Boot in Safe Mode (Android)

If a third-party app is causing the issue, Safe Mode can help identify it.

Hold the power button, then long-press Power Off and select Safe Mode.
Uninstall recently downloaded apps if the flickering stops.

5. Reset Display Settings

Android: Go to Settings > Display > Reset display settings.
iPhone: Go to Settings > Accessibility > Display & Text Size and disable Auto-Brightness or Reduce Motion.

6. Factory Reset (Last Resort)

If software issues persist, back up your data and perform a factory reset.

Android: Settings > System > Reset > Factory Data Reset.
iPhone: Settings > General > Transfer or Reset iPhone > Erase All Content and Settings.

How to Fix a Blinking Phone Screen After Dropped

If your phone started flickering after a fall, the issue is likely hardware-related. Here’s what you can do:

1. Inspect for Physical Damage

Check for cracks or visible damage to the screen.
Look for loose connections inside (requires disassembly if experienced).

2. Apply Gentle Pressure

Sometimes, the display connector becomes loose.

Power off the phone.
Apply slight pressure around the edges of the screen (near the bezel).
Restart the phone to see if flickering stops.

3. Replace the Screen

If the flickering persists, the screen or digitizer may be damaged.

Consider professional repair or a DIY screen replacement (if comfortable).

4. Check for Internal Damage

If the flickering is accompanied by other issues (unresponsive touch, distorted colors), the GPU or motherboard may be damaged. Read more: How to know if your phone has internal damage after dropping?
