GPS / Geo-Location data lost on edit

[foss-]

Reproduce

1. select Draw for an image with GPS data
2. enable Keep EXIF option so that metadata is kept
3. draw on image
4. tap disc icon to save image
5. see confirmation dialog

Currently

When looking at the edited image, the GPS data is gone.

Expected

All metadata should be kept.

Check image source in the options, it gives info about geo

Thanks for the response. When I open Settings > Image source I see Photo picker selected. Since that option mentions Has issues receiving EXIF metadata I switched to Gallery and repeated above steps but saved image still has no GPS data.

[T8RIN]

Hm, even with last option?

Third option File explorer works and keeps the GPS metadata 🎉
This is very helpful, been wondering about this for a long time.

Would it make sense to remember the EXIF setting last used? My personal use-case requires this to be on, but it is always off when I go into editing.

[T8RIN]

Hm, i can add an additional setting if you want :)

[foss-]

Not sure how this is best handled. Follow last used state avoids an additional settings option and my be sufficient. Certainly a setting is also possible - not sure which section would fit and adding yet another section to settings would make them even more crowded so not a fan. But if you have an existing category in mind sure.

In the additional exif category, i prefer this way because it's much easier to implement 👀

[foss-]

Sure, you're the boss and since I can't code happy either way 🚀

Do you want a separate issue for that feature request?

EDIT: #655

[T8RIN]

Yup, that's would be great 💯

Retested 2.6.0a2 and still struggling to keep EXIF information after using draw with an image.

• Keep EXIF option is enabled
• Image Source is File explorer

And yet the edited image has no GPS information while the original has GPS information.

[foss-]

Persisting in 2.6.0a3. Could you re-open this issue? Sadly none of the three image source options allows to keep the GPS information in the image when saving a draw edit. The timestamp was kept with all three options.

This feels like a problem in Android behavior.

Found a similar issue filed against Nextcloud and fm-sys pointed out that Stripping EXIF data is part of the android Q privacy feature set. Starting with Android 10 (or 11?), apps need to explicitly specify that they want to receive Metadata..

If you'd be willing to take a look how to specifically request to receive EXIF data when opening an image, that might solve this issue.

In comment nextcloud/android#6248 (comment) there are also three links about the behavior which are:

Thanks, i will check

I did this i think, checked with latest image source and location not lost on android 14 😄
