What should you check if you suspect your mobile device camera is being used to spy on you?

When you suspect that your mobile device camera is being used to spy on you, checking your monthly bill and data usage can provide valuable insights into potential unauthorized activities. If malware or an unauthorized application is using your camera, it may also consume a large amount of data, which would be reflected in your bill. Sudden increases in data usage or unfamiliar charges can indicate that something unusual is happening with your device, including the possibility that it's being targeted for surveillance.

Monitoring the data usage allows you to identify any apps or processes that are consuming more data than expected, helping you to pinpoint any suspicious activity that may involve the camera or other features. This awareness can lead you to take appropriate actions, such as uninstalling potentially harmful apps or seeking professional assistance to secure your device.

Other options, while they may be valid checks for other issues, do not specifically help in identifying spying concerns related to the camera. The battery status might indicate heavy usage but wouldn’t directly expose the nature of that usage. Available storage could reflect app activity but would not conclusively show unauthorized access. The device warranty is unrelated to operational issues and would not provide any insight into suspicious camera activity.
