**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
