If you're looking for a secure lock for your private photos, videos, and other files, then you can download the app from Google Play. With it, you can hide photos, videos, and other files so that no one else can view them.

With this, you can also set a fingerprint lock so you can identify yourself.

You can also set a PIN or pattern to protect your files.

It's very easy to use, and you can do it in a few minutes.

To set up the fingerprint lock, you need to enable the fingerprint function in the app settings. To do this, you need to enable Accessibility Services in the device settings.
