Some illegal videos may not be saved to the album because they may violate the provisions of the platform or the law. If the video you want to save violates the regulations, it is recommended that you find other legal and compliant video resources.

If the video platform does not allow direct saving of videos, you can try to use a screen recording tool. For example, the steps are:

1. Download a video platform APP on your mobile phone and log in.

2. Play the short video that needs to be saved.

3. In the short video playback interface, click anywhere on the interface.

4. Exit the short video playback interface, press and hold the power button + volume up button at the same time until you enter screen recording mode.

5. Release the volume up button and keep pressing the power button until the video recording is completed.

6. After exiting the screen recording mode, there will be a thumbnail, click on it, there will be a share button in the upper right corner, click on it, and choose to save the video.

It should be noted that there may be copyright issues in saving the video. If you save it without the authorization of the copyright owner, you may be suspected of copyright infringement. It is recommended that you save it with caution.
