How to troubleshoot when the Samsung phone display is unexpectedly grayscale
If the color on your phone's screen suddenly looks all black and white, some features of your phone may have been activated. Features such as Bedtime, Dark mode, or Visibility enhancements mode may have been accidentally turned on or automatically activated. Follow the guide below to adjust these features.
Before you try the recommendations below, be sure to check if your device's software and related apps are updated to the latest version. To update your mobile device's software, follow these steps:
Step 1. Go to Settings > Software update.
Step 2. Tap on Download and install.
Step 3. Follow the on-screen instructions.
If Bedtime mode is enabled, all colors on the screen will be displayed in grayscale. Bedtime mode lets you get ready for bed by turning your screen black and white and muting calls, notifications and other sounds. You can activate Bedtime mode to reduce eye strain and prevent sleep disturbances before going to sleep. If Bedtime mode is enabled, follow the steps below to turn it off.

Step 2. Scroll down and tap Bedtime mode.
Step 3. To disable the Bedtime mode, tap the switch next to Turn on as scheduled so that it's off.
Note:
- This feature operates according to a schedule and is automatically deactivated after a scheduled time.
- Bedtime mode may not be supported depending on the device, and the menu name may be Wind Down.
Dark mode allows you to reduce eye strain when using the device at night or in a dark place. You can also set a schedule for applying Dark mode. If Dark mode is enabled, follow the steps below to turn it off.
Step 1. Launch the Settings app, and then select Display.
Step 2. Check if the Dark mode is enabled, and then tap the Light mode.

Set a schedule for Dark mode.

Step 1. Tap the Dark mode settings in Display menu.
Step 2. Tap the switch next to Turn on as scheduled. Choose Sunset to sunrise to schedule Dark mode to turn on between sunset and sunrise. In this case, Location needs to be turned on.
