**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 and in this video https://youtu.be/Rf3WndFgftI

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).

If you are running Android 9 (Android P) or newer you don't necessarily need this app. You can also use the built-in Digital Wellbeing/Wind Down setting. However it does not 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
