Turn Location Access On or Off auf Huawei
Location access on Huawei phones works as a master switch. When it is turned off, no app can read GPS, Wi-Fi, or mobile network positioning, no matter which permissions you granted individually beforehand.
This is useful if you want to save battery, hide your movements from all apps at once, or troubleshoot a location bug without checking every app one by one. It is not the right fix if only a single app misbehaves, since it also blocks navigation, weather, and delivery apps that rely on your position.
To change the setting, go to Open the settings ➔ Tap on Location ➔ Activate or deactivate Access my location. Turning the toggle off greys out location for every app immediately; turning it back on restores access based on whatever permissions each app already had.
Keep in mind that some system functions, such as emergency location sharing or lost-device tracking, may stop working while this setting is off.
