What to do if TubeMate downloads a video but it’s not shown in your phone gallery not save:
Verify Storage Permissions:
it requests storage access permission to download files to the device. Make sure that storage access is turned on in Settings > Apps > TubeMate > Permissions.
Manually Move Files to a Visible Folder:
Some videos downloaded from TubeMate get stored in their internal folder that may not be visible in the gallery. Open your video folder in a file manager and move those videos to your Movies, Videos, or DCIM folder so they can show up in the gallery.
Force Update Media Library:
No need to uninstall and reinstall your apps. Restart the device; the media scanner will update. If the problem persists, use an app such as Media Rescan to refresh props in your gallery manually.
Log into Storage Space Issues:
The newly downloaded files cannot be saved if your phone’s storage is whole. Delete unnecessary files or transfer videos to an SD card or cloud storage to free up space.
