If your Galaxy S25 Ultra suddenly turns black and white, don’t worry. It’s not a hardware problem. This usually happens when a display feature or mode changes the screen color to grayscale. You can fix it easily once you know where to look.
The issue is often caused by Bedtime Mode, Wind Down Mode, or accessibility settings that use grayscale filters. Let’s go through the steps to bring your screen colors back.
Why Your Galaxy S25 Ultra Screen Turned Black and White
- Bedtime Mode or Wind Down Mode is active.
- Grayscale or Color Filter is enabled in Accessibility settings.
- Power Saving Mode is restricting display options.
- Digital Wellbeing’s Focus Mode is turned on.
- Minor software glitches or temporary bugs.
Turn Off Bedtime Mode.
Bedtime Mode helps reduce distractions and prepares your eyes for sleep. However, it also changes the screen to black and white.
- Open Settings, and then tap Modes and Routines.
- Tap Sleep or Bedtime Mode, and then turn it off.
Once it’s disabled, the screen should return to normal colors.
Disable Grayscale in Accessibility Settings.
Grayscale can also be enabled manually in Accessibility settings. This mode is often used to reduce visual strain or discourage excessive screen use.
- Open Settings, and then tap Accessibility.
- Tap Visibility enhancements, and then tap Color filter. Toggle the switch off if it is on.
You can also check the preview window to make sure color is restored.
Check Digital Wellbeing.
The Digital Wellbeing feature sometimes activates grayscale through Focus or Wind Down routines.
- Open Settings, and then tap Digital Wellbeing and parental controls.
- Tap Bedtime Mode or Focus Mode, and then turn them off if enabled.
After this, exit to the home screen and verify that your display has regained color.
Disable Power Saving Mode.
Power Saving Mode can limit performance and screen effects, sometimes affecting display appearance.
- Open Settings, and then tap Battery.
- Tap Power saving, and then toggle it off.
Once disabled, your phone should display full color again.
Restart Your Phone.
A simple restart can clear out temporary glitches that cause the screen to appear monochrome.
- Swipe down from the top-right corner to open Quick Settings.
- Tap the Power icon, and then select Restart.
After rebooting, check if the screen color returns to normal.
If your Galaxy S25 Ultra display is still monochrome, make sure no third-party apps are controlling display color. Apps that manage focus, sleep, or reading modes can override system settings.
Restoring the original color of your screen takes only a few minutes, and you’ll have your bright, vivid display back to normal.
FAQs
Why does my Galaxy S25 Ultra turn black and white at night?
This is usually caused by Bedtime Mode or Wind Down Mode, which activates automatically during your sleep schedule to reduce eye strain.
Can a software update cause the monochrome effect?
Sometimes, but it’s rare. A recent update might reset or enable certain display features. Checking your modes and accessibility settings usually resolves it.
Does grayscale save battery on the Galaxy S25 Ultra?
Yes, slightly. Since fewer colors are displayed, it uses less power on the AMOLED screen, but the effect is minimal compared to Power Saving Mode.
