Attaching a screenshot results in error with Samsung phones

[raherin]

Sometimes when using a Samsung phone, the app returns an error when attaching a screenshot as a photo. This appears to be a specific issue with the way Samsung's flavor of Android handles the naming of screenshots by adding the name of the app in the screenshot as a prefix to the photo. If the name of the app contains any spaces, the photo will fail to save to the app.

To reproduce the issue:

1. Add a Survey point.
2. Choose to add a photo from gallery.
3. Switch to another app to make a screenshot.
4. Make the screenshot.
5. Switch back to Mergin Maps app.
6. Select the screenshot which you just made.
7. Try to save.

Adding a screenshot of 'Chrome' browser (works):

Adding a screenshot of 'Play Store' (fails):

In the diagnostic log, I see this when the photo attachment fails:

Test reproduced on device: Samsung A53/Android (15.0) Mergin Maps Build: 733911

Steps to reproduce:

1. Add a new feature (Survey layer).
2. Choose to add a photo from gallery.
3. Switch to another app (Play store) to make a screenshot.
4. Make the screenshot from Play store.
5. Switch back to Mergin Maps app.
6. Select the screenshot which you made.
7. Save the feature.

Actual Result: After taking a screenshot of the application (Play store) and attempting to add it from the gallery, the process fails. The application displays an error message: "Failed to process the image"

Comment: Despite the fact, that adding the screenshot of the application (Play store) from the gallery failed, this screenshot is uploaded into the QGIS.
