.NET MAUI 10: MediaPicker.PickPhotosAsync Fails to Return Location EXIF Data on Android

[stephenquan]

In .NET MAUI 10 (e.g., MauiVersion=10.0.0), MediaPicker.PickPhotosAsync appears to redact or corrupt location metadata on Android devices. In .NET MAUI 9 (e.g., MauiVersion=9.0.120), MediaPicker.PickPhotoAsync is able to read location metadata normally.

Github Repo:

• https://github.com/stephenquan/MauiEXIFApp

Platform:

• Android

Steps to reproduce

• 1. Clean the bin and obj folders of the MauiEXIFApp project.
• 2. Open MauiEXIFApp.csproj.
• 3. Set <MauiVersion> to either 9.0.120 (working) or 10.0.0 (not working).
• 4. Build and deploy the app to an Android device (e.g., Samsung S21 FE running Android 16).
• 5. Launch the app.
• 6. Use Pick Photo and select an image that you know contains location metadata.
• 7. In the 9.0.x version, the location information is displayed correctly. In the 10.0.x version, the location values are returned as NaN.
• 8. All other EXIF metadata remains intact.

Troubleshooting

• The app includes ACCESS_MEDIA_LOCATION, READ_EXTERNAL_STORAGE and READ_MEDIA_IMAGES in the AndroidManifest.xml.
• I attempted to request the ACCESS_MEDIA_LOCATION permission before launching MediaPicker.
• I tested additional .NET MAUI v10 versions (e.g., 10.0.30), but the issue still persists.
• I tested multiple .NET MAUI v9 versions (e.g., 9.0.60), and location metadata works correctly.
