Why is it not possible to stop FRITZ!App WLAN?
FRITZ!App WLAN is an app with functions at system level that make it possible to establish wireless connections and analyze the wireless environment in Android. It is therefore necessary for FRITZ!App WLAN to always remain active in the background once it is started. It is not necessary to stop the app, nor was this intended. However, you can force the app to stop in the Android settings under "Apps > FRITZ!App WLAN".
