Tone

Go to:

Settings → Display & Brightness

Turn off:

• True Tone
• Night Shift

These features adjust screen color and brightness automatically, which may look like flickering.

4. Check Storage Space

Low storage can cause system instability.

Go to:

Settings → General → iPhone Storage

If storage is almost full, delete unused apps or large files.

Devices with less than 1GB free space may behave unpredictably.

5. Update iOS

Sometimes screen flickering starts after a buggy update.

Go to:

Settings → General → Software Update

Install the latest stable version if available.

6. Reset All Settings

If flickering continues:

Settings → General → Transfer or Reset iPhone → Reset → Reset All Settings

This will not delete photos or apps but resets display and system settings.

7. Remove Screen Protector

A damaged or low-quality screen protector may interfere with the display.

Remove it and check if flickering improves.

8. Check for Physical Damage

If you recently dropped your phone, hardware damage may be the cause.

Signs include:

• Vertical or horizontal lines
• Screen discoloration
• Flickering only in certain areas
• Touch issues along with flicker

In this case, screen replacement may be required.

When Should You Seek Professional Help?

You should visit a repair technician if:

• Flickering continues after reset
• Screen randomly turns black
• Display only works at certain angles
• Phone was exposed to water

These may indicate internal display or logic board issues.
