[Android versions lower than 6.0]
Due to the nature of the operating system, individual permissions cannot be withdrawn. Therefore, all permissions are required.
Therefore, we recommend upgrading your operating system as provided by the manufacturer. If the manufacturer does not provide such permissions, uninstalling the app will prevent the app from accessing the permissions.
Furthermore, even if your operating system is upgraded, the permissions agreed to in existing apps will not change. Therefore, to reset permissions, you must delete and reinstall the app.
