After using "Fix date taken" what exactly happens? Does it save any date as "Date taken" in EXIF? If it saves, then which date it saved?

After using "Fix date taken"

nothing happened. The modified date of the photo and EXIF date keep untouched.

Does file's "Date created" is the same as EXIF "Date taken"?

Does file's "Date created" is the same as EXIF "Date taken"?

No.
Before and after "Fix date", the outputs below are identical.

If I understand the "fix date taken" feature correctly, it won't update the last modified date to match the exif date taken. In case that is what you expected it to do.

Here's an explanation SimpleMobileTools/Simple-Gallery#2951 that should still be valid:

And here's a short video demonstrating the feature.

The photos are grouped by date taken (monthly), but as you can see the photo is assigned to "Unbekannt" (unknown) although it does have a date taken (exif data). After using the "fix date taken" feature it is correctly assigned to January 2024. Both the modified date and the date taken stay unchanged.
