Gray-Switch (Grayscale) のアプリ分析 1月13日

**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 ---------------------------------------- Provider Identification: Vegard IT GmbH Ziegelhüttenstraße 33 63768 Hösbach Germany Represented by: Sebastian Thomschke, Patrick Spielmann e-Mail: android-support@vegardit.com Register Entry in Handelsregister: Register Court: Amtsgericht Aschaffenburg Register Number: HRB 16384 V.A.T.
