Gray-Switch (Grayscale)

Gray-Switch (Grayscale)

**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 so are provided within the app and in this video https://youtu.

be/Rf3WndFgftIGray-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.

----------------------------------------Declaration of AccessibilityService-API UsageThe optional feature to exclude certain apps from grayscale mode requires the usage of the AccessibilityService-API.

The AccessibilityService-API is only used to determine the ID of current foreground application to automatically enable or disable the grayscale mode.

No data is collected.

----------------------------------------**Setup:**Connect your phone to a PC with Android SDK Platform Tools installed and execute the following command after you installed the app on the phone:adb shell pm grant com.
