When the Tello app takes a video it is stored on the phone or tablet somewhere, using the iOS file system. Any iOS file recovery efforts would be the same no matter what app generated the video or photo file.
Until that file gets overwritten by something else, it's still there. Possibly, rather than using Apple's 'Recently Deleted' album, one would have to use a third-party recovery utility.
If the device was Android, or a Windows computer, I could be a lot more specific and a lot more help, sorry.
Hi, on IOS the Tello app does not store the photos or videos automatically to the iPhone you need to save them yourself...unless I’m missing something to tick
Will look again to see if there is any setting to change...
Wish I had an iPhone to play with, this just seems doable to me... or better yet - wish an iOS Guru would show up in this thread... maybe if the thread title was edited to include the term "iOS file recovery"?
