If you have not set your settings to save your TikTok videos to your device each time you post a new video, you will need to switch manually.
There are several ways to do this.
The fastest way is to tap and hold the video you want to save, whether it’s yours or someone else’s. A “save video” option will appear, allowing you to add it to the camera or share it via email or text.
You can also click the share button below the comment icon that appears on the right side of the videos in the app. From there, you can save the video to your camera or post it to other social media sites.
If you want to save videos you’ve liked in the past, go to your account and click the “heart” icon below your resume. This section shows a current list of all the videos you’ve ever liked.
To make sure that all your videos are automatically saved in the future, turn on the “save device” option before posting TikTok. It will remember your choice the next time you post a video. You can see your saved TikToks in the camera of your smartphone.
