Gray-Switch (Grayscale/Monochrome Display) for Android

By Vegard IT Free

Developer's Description

**IMPORTANT** If your phone is not rooted, you need to manually grant the WRITE_SECURE_SETTINGS permission to the app, detailed instructions on how to do this are provided within the app.

Gray-Switch allows you to conveniently switch your device's display mode between full color and grayscale either using a quick settings tile (Android 7 or newer), a launcher icon, automatically when the battery charge has fallen below a configured value, and/or during a configurable time schedule (e.g. at night time).

The app uses the Monochromacy setting usually found in the Developer options at Settings > System > Developer Options > Simulate color space > Monochromacy.

If you are running Android 9 (Android P) or newer you don't necessarily need this app. Instead you can use the built-in Digital Wellbeing/Wind Down setting. However, it doesn't allow you to exclude applications from grayscale mode nor automatically enables grayscale mode on low battery.

**Setup:** Connect your phone to a PC with Android SDK installed and execute the following command after you installed the app:

adb shell pm grant com.vegardit.grayswitch android.permission.WRITE_SECURE_SETTINGS
