Fix iPhone Black and White: 7 Real Solutions

If your iPhone screen has suddenly turned black and white, it’s almost always a software setting called Color Filters or a stuck Accessibility shortcut, not a hardware failure. The fix is usually a few taps in Settings, though a hard restart or display replacement may be needed in rarer cases. This guide covers every known cause and the exact steps to restore color.

What Causes an iPhone to Display in Black and White?

Monochrome display on an iPhone is a feature, not a bug. Apple includes a Color Filters option under Accessibility that can turn the entire screen grayscale. It’s designed for people with color vision deficiencies, but it’s easy to enable accidentally, especially via the Side Button shortcut or Back Tap. Other causes include:

• Accidental triple-click of the Side or Home button (if Accessibility Shortcut is set to Color Filters).
• Back Tap gestures (Settings > Accessibility > Touch > Back Tap) triggering the filter when you tap the back of the phone.
• Zoom mode with a grayscale filter applied (Settings > Accessibility > Zoom > Zoom Filter).
• Low Power Mode does not cause this, contrary to a common myth.
• Hardware damage (e.g., a cracked LCD or loose display cable) can produce a monochrome or distorted image, though this is less common than a software toggle.

Quick Fixes to Try First

Before diving into Settings, try these two simple actions—they resolve most cases in seconds.

1. Triple-click the Side button (or Home button on older models) three times quickly. If Color Filters is set as the Accessibility Shortcut, this toggles it off.
2. Force restart your iPhone: Press and release Volume Up, then Volume Down, then hold the Side button until the Apple logo appears (for models with Face ID). On older models, hold Home + Side (or Home + Top) together. This clears temporary glitches that might be causing the filter to stick.

If neither works, proceed to the Settings checks below.

Turning Off Color Filters in Settings

The most common culprit is the Color Filters toggle. Here’s how to disable it:

1. Open Settings > Accessibility.
2. Tap Display & Text Size.
3. Tap Color Filters.
4. Toggle Color Filters to Off (green switch turns gray).

If the toggle is already off but the screen is still monochrome, check the Accessibility Shortcut (Settings > Accessibility > Accessibility Shortcut) and ensure Color Filters isn’t checked there. Also, verify Back Tap (Settings > Accessibility > Touch > Back Tap) isn’t assigned to Color Filters—a common accidental trigger when you set your phone down.

Other Settings That Can Cause Monochrome

Two less obvious settings can also produce a black-and-white effect:

• Zoom Filter: If you use the Zoom accessibility feature, it can apply a grayscale filter to the magnified area. Go to Settings > Accessibility > Zoom, tap Zoom Filter, and select None. You can also double-tap with three fingers to bring up the Zoom controls and reset the filter there.
• Invert Colors: While not grayscale, Smart Invert can make colors look washed out or odd. Check Settings > Accessibility > Display & Text Size and ensure Smart Invert is off.

If you have a physical keyboard connected (via Bluetooth), some keyboard shortcuts (like Command+Option+Control+8 on Mac) can toggle grayscale—but this is rare on iPhone.

When It’s a Hardware Problem

If you’ve disabled all filters and the screen remains black and white, the issue may be physical. A damaged display or a loose internal connector can cause the screen to lose color data. Signs of hardware failure include:

• The screen is also flickering, showing lines, or has dead pixels.
• The monochrome effect appeared after a drop or liquid exposure.
• The screen responds to touch but colors are permanently off, even in the Settings app.

In these cases, a visit to an Apple Store or an authorized repair center is the safest option. DIY display replacement is possible but risks further damage and voids warranty—consider it only if you’re experienced.

How to Prevent Accidental Grayscale

Once you’ve fixed it, you can stop it from happening again:

• Change the Accessibility Shortcut to something else (like VoiceOver or Switch Control) so triple-click doesn’t trigger filters.
• Turn off Back Tap or assign it to a non-visual action (e.g., Screenshot).
• If you use Zoom, set the filter to None and avoid the three-finger double-tap gesture.

Frequently Asked Questions

Why did my iPhone screen go black and white after an iOS update?

iOS updates can reset some accessibility settings or introduce bugs. Check Color Filters and Accessibility Shortcut first—they may have been toggled on during the update. A force restart often resolves update-related glitches.

Does Low Power Mode cause a black and white screen?

No. Low Power Mode only reduces background activity and dims the screen slightly; it does not change color output. If your screen is monochrome while in Low Power Mode, it’s coincidental—check the settings above.

Can a black and white screen drain my battery faster?

No, grayscale doesn’t significantly affect battery life on modern iPhones. OLED displays may use slightly less power with black pixels, but the difference is negligible in practice.

Will resetting all settings fix the issue?

Yes, if a misconfigured accessibility setting is the cause. Go to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings. This won’t delete your data, but it will reset Wi-Fi passwords, wallpapers, and accessibility preferences to defaults.

Is there a way to use grayscale on purpose?

Yes, some people use it to reduce screen time or eye strain. Enable it via Settings > Accessibility > Display & Text Size > Color Filters and toggle on Grayscale. You can also set it as an Accessibility Shortcut for quick toggling.

What if the screen is black and white only in one app?

That’s likely an app-specific setting, not a system issue. Check the app’s own display or theme settings—some apps (like reading apps) have a grayscale or night mode. If it persists, force-quit the app and reopen it.
