> actually using the geolocation is an extremely niche usecase for images uploaded from mobile browsers
Is it only for mobile browsers? The article makes it sound [0] as if it is a general thing, even when sharing through bluetooth, and that only copying the image via usb connection allows you to keep geolocation in exif. Not sure what happens when you upload to native apps, eg to some cloud storage app (photo specific or not). I definitely want my location to stay when I make a cloud backup of my photos with an app intended for that.

>> Using a "Progressive Web App" doesn't work either. So, can users transfer their photos via Bluetooth or QuickShare? No. That's now broken as well. You can't even directly share via email without the location being stripped away. Literally the only way to get a photo with geolocation intact is to plug in a USB cable, copy the photo to your computer, and then upload it via a desktop web browser?
I'm guessing they changed the default behavior from "include metadata" to "strip metadata" so now any app that wants metadata has to request it explicitly, and any older apps which don't know how to make such a request are simply unable to get location data?
Seems like this is possibly related to the ACCESS_MEDIA_LOCATION permission[1], and Google's recent efforts to force applications to migrate to the scoped storage API. See: https://developer.android.com/training/data-storage/shared/m...
Probably someone more versed in Android's APIs could give a better explanation.

Yes, it's about that permission. It's not even that recent, it has been implemented since Android 10. I think it's summarized quite well here [0]:
If your app targets Android 10 (API level 29) or higher and needs to retrieve unredacted EXIF metadata from photos, you need to declare the ACCESS_MEDIA_LOCATION permission in your app's manifest, then request this permission at runtime.
So if the app-developer didn't take explicit effort to request this data (and the user-permission for it), his app will not receive it.

No way they broke it for Google Photos. Anyone who needs location and doesn’t do cables, or can’t figure this out, can simply subscribe!
Can you compress a folder with a photo it and then email that? Just curious.

If the app that creates the compressed file uses the media API to get the file and doesn't have the permission to get location-info, the data will be stripped before the OS is handing the file over to that app. This is likely different if the app uses the READ_EXTERNAL_STORAGE permission and API's to read the files though, which is a legacy permission that was mainly kept for file managers now...
