One way to do this is by controlling which permissions you grant mobile applications when installing them. Before downloading an app, verify what access and information the application requires and only give permission for the necessary functions. You can disable some of the default settings that may compromise your privacy, unless they are needed for the app to function. Additionally, consider disabling location tracking services or allowing access only while using the application. To further protect yourself, read third-party reviews and research an app before downloading it as some apps may collect more than necessary data or have malicious intent. Finally, regularly check your phone's settings to ensure that installed apps are not accessing unnecessary data in the background.
