Gray-Switch (Grayscale)

Vegard IT GmbH

About this app

**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/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.

----------------------------------------
Declaration of AccessibilityService-API Usage

The 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.vegardit.grayswitch android.permission.WRITE_SECURE_SETTINGS

Ratings and reviews

I wish there was a feature to turn the grayscale mode back on automatically. Sometimes I need color for something and turn grayscale off, and then forget to turn it back on. I wish this app would either give me a button to temporarily pause grayscale for X minutes instead of just on/off, or automatically turn on if it's currently off every X minutes. I know there's scheduling and exclusions, but there isn't as many options as I'd like to get the above effect that forces me back into grayscale.

Perfect. Once it's set up, you can swipe down and touch grayscale to toggle between grayscale and color. No fuss, it just works, exactly how you'd hope. Great tool for lowering the draw to your phone as a distraction, while being able to quickly switch back to color when you want to take pictures, watch shows, whatever. It can be a little hard to set up, but the instructions are spot on, ask a nerdfriend to help if needed.

Wasn't as difficult to install and worked great for a while. It definitely helped with extending the battery when switched on at low percentage. But after a few months it started malfunctioning. For example, it started to flicker forth and back from color to grayscale mode, so eventually I uninstalled it. Then my phone was stuck in grayscale mode. To turn the color mode back on I had to reinstall the app.
