Spy Camera OS 3 is a small and simple app that allows you to capture candid moments without anyone knowing. With over 1 million downloads, this app is the perfect tool for capturing images and videos discreetly. You can run it in the background and even with the screen off, making it ideal for hidden surveillance. It offers features like burst shot, auto shot with delay, face detection auto shot, and black screen touch capture. You can also hide or customize your folders, record videos (experimental), save to internal or external storage, and even send files via email. With upcoming updates, more advanced configurations will be added to enhance your experience.
