App Lock

Samsung does offer a feature called "Secure Folder" which can be used to lock and secure apps, files, photos, and more with PIN, pattern, password, fingerprint, or iris scan. It provides an isolated space on your device where you can keep your private apps and data separate from the rest of your device. While this is not exactly an "App Lock" feature built into each individual app, it serves a similar purpose of securing your sensitive data.

Here's how to use Secure Folder:

1. Open Settings on your Samsung device.
2. Scroll down and find "Biometrics and Security" or "Lock Screen and Security" (the exact wording may vary based on your device and software version).
3. Look for "Secure Folder" and tap on it.
4. Follow the on-screen instructions to set up your Secure Folder.
5. Once set up, you can add apps, photos, files, etc., to the Secure Folder.
6. To access the Secure Folder, you'll need to use your chosen authentication method (PIN, pattern, password, fingerprint, or iris scan).

While Secure Folder may not be exactly what you're looking for, it provides a secure way to lock and protect your apps and data without the need for a third-party app. If you're looking for more specific app-level locking without Secure Folder, you may want to explore third-party app lockers available on the Google Play Store. These apps can offer more granular control over individual app locks using PIN, fingerprint, or face recognition.

Secure Folder is known, but not a practical thing, i need to lock some apps without the need to create a whole secure space, my kids use my phone i just dont want them to access couple of apps, there must be an improvement in this regard ...
