How to fix the issue?
Here are a few fixes that might help you resolve black white screen issue on your phone.
Restart your device
Most of the time your phone screen turns black and white because of some temporary glitches or minor bugs, if that is the case then restarting your phone can resolve this issue. Restart your phone properly, and then check if the phone screen is still black and white.
Disable Battery saver
When your phone’s battery is running low, it automatically switches to a battery-saver or power-saving mode. These modes often reduce the device’s functionality to conserve power, and one way they do this is by limiting the display to black and white. To disable the battery saver follow the steps below:

- Open the Settings app on your phone and tap on the Battery option.
- Tap on the Battery Saver option.
- Turn the toggle off beside the Use Battery Saver.
Uninstall apps
If you’ve recently added new apps to your phone and the problem started after that, try removing them. Sometimes, a few apps conflict with the phone’s functionality, because it wasn’t installed properly or have some bugs, uninstalling these apps can fix the issue.
Disable Colour correction and Colour Inversion
Another possibility is that you’ve accidentally activated an accessibility feature that turns your screen into black and white. There are options for colour inversion and correction that can be enabled in the settings.
If you’ve turned on any of these features, you can return to the settings and disable them to return your phone to colour mode. To disable colour correction and colour inversion on your phone follow the steps below:

- Open the Settings on your phone, scroll down a bit and tap on Accessibility.
- In Accessibility, tap on the Colour and Motion option.
- Make sure both the Colour correction and Colour inversion features are disabled.
Disable Greyscale in Bedtime mode
Bedtime mode on your smartphone turns the screen to greyscale automatically. If you use the bedtime mode on your smartphone, then it is the most probable cause of the black and white screen. To disable the greyscale in bedtime mode, follow the steps below:

- Open the Settings on your phone, scroll down, and find Digital Wellbeing and Parental Control and tap on it.
- Tap on the Bedtime mode option.
- Now, tap on the Customise option.
- Tap on Screen options at bedtime.
- Turn the toggle beside the Greyscale.

- In the system, tap on Developer options.
