🐛 Front camera returns null metadata

[agrik-monere]

What's happening?

Image taken by front camera returns null metadata:

"exif": {
"ShutterSpeedValue": null,
"MaxApertureValue": null,
"ExposureProgram": null,
"ResolutionUnit": null,
"ColorSpace": null,
"CompressedBitsPerPixel": null,
"MakerNote": null,
"SubSecTimeOriginal": null,
"SubSecTimeDigitized": null,
"MeteringMode": null,
"SubSecTime": null,
"ExifVersion": null,
"BitsPerSample": null,
"ImageWidth": "4224",
"YResolution": null,
"Software": null,
"XResolution": null,
"Orientation": "0",
"ImageLength": "3136",
"YCbCrPositioning": null,
"Make": null,
"Model": null,
"InteroperabilityIndex": null,
"Flash": null,
"ExposureBiasValue": null,
"FocalLength": null,
"ExposureTime": null,
"ISOSpeedRatings": null,
"WhiteBalance": null,
"DateTime": null,
"DateTimeDigitized": null,
"FNumber": null
}

The back camera metadata is perfect though

Reproduceable Code

const imageFile = await camera.current.takePhoto({
      qualityPrioritization: 'quality',
});
Exif.getExif(imageFile.path).then(res => console.log("metadata-->", res))

Guten Tag, Hans here! 🍻 Thank you for providing detailed information about your issue. It looks like you're experiencing a valid bug with the front camera metadata returning null.

Since you mentioned that you can reproduce this issue in the VisionCamera Example app, it helps narrow down the problem. If you haven't already, please check if there are any updates or patches available for your version, and make sure the device is compatible with the library's features.

If the problem persists, it might be helpful to gather additional logs from adb logcat while reproducing the issue, just to help mrousavy diagnose it further. Keep up ze good work, and let's see if we can get this resolved!

Note: If you think I made a mistake, please ping @mrousavy to take a look.
