The app currently has "Fix Date Taken value" for fixing bugs with date discrepancies. See the description of how it works here: #88 (comment). Do you need the date changing feature for something else, or is it enough?

Thank you for the quick reply.
It doesn't help me because I find this problem after erasing all the exif data so this feature cannot find the right date when I try to fix it. It would be nice if I could set it manually
Aga-C commentedon Jan 1, 2025
Thanks for the reply. So, I have another question: would you like to edit the date taken in EXIF metadata, or file's creation date? Or both at once?
Gravity2106 commentedon Jan 1, 2025
Probably I would prefer to edit at least the date taken in EXIF metadata as in this case I want to keep the order of the pictures for the future and that would be also the case if I do a trip and I want to track what I do each day.
Happy new year!

Replying to this issue, as it has not yet been implemented and I'm missing the feature as well.
Especially when you import photos into Fossify Gallery from other phones / galleries or just download them, and they do not have the EXIF data for "date taken", you loose the order of your pictures with no way of recovering it - not even manually.
From my experience, this is relevant for screenshots which for some reason didn't have the "date taken" EXIF metadata and instead encoded the "date taken" inside of the name of the screenshot.
An alternative fix for the issue I'm having - and one that would help me perhaps even more then the original would be to fallback to the image name itself for a "date taken" token, as I believe they ought to be standardised.
If this gets any traction, I'm happy to supply my format of screenshots' names across multiple different devices.
Additional details: proposed capture-date editing workflow
For the manual editing part of this request, I would like to:
The important distinction is between the embedded capture date, the filesystem's modified timestamp and the gallery/media index. I want to add or correct the embedded value so it survives copying the image to another device or opening it in another compatible app. Fix Date Taken value cannot create that missing value because it reads an existing EXIF date into the index.
Please include PNG screenshots as well as JPEG photos where writing is supported, preserve image pixels and unrelated metadata, and keep processing on-device. Unsupported formats or unavailable write access should be explained clearly.
The filename-based fallback mentioned above remains an alternative for my use case; the workflow here describes manual capture-date editing. Related request: #1139.
