if you’re not seeing an EXIF tag like GPSHPositioningError actually stored in your image file on your own device (or in your personal online storage), the only way accuracy will get onto your observation is if you have the iNat Android app determne the location for you (as opposed to reading it from your image file), or if you manually input a location including an accuracy value.
just looking at a few of your observaitons, it looks like you’re using a PIxel 3a, which will not capture any sort of accuracy or error field in the image files using its stock camera app, and just looking at a few of your photos (ex. https://www.inaturalist.org/photos/436362421), there’s no metadata loaded from your image files to the photo record that looks like an accuracy or error tag.
even though jsuplick claims that there is an accuracy tag on the image file, i can’t find evidence of this in the metadata loaded to the photo records from back in the day (ex. https://www.inaturalist.org/photos/117301458), and i’m guessing they may be confusing an altitude tag for an accuracy tag.
as noted above, if accuracy / error is not recorded in the image file itself, the only way accuracy gets onto the observation is if the user manually inputs it or uses the iNat Android app to determine the location.
when you “start in the iNat app and take photos”, that is one of the workflows that uses the iNat Android app – as opposed to your camera app – to determine the location, and that’s why that will add accuracy to your observation (but not the photo itself).

it looks like @teelbee’s iOS issue was resolved in another thread, and nobody else in this thread provided any other examples to look at in this thread. so i suspect that people here just don’t understand what their own Android phones record as locations by default and what other options are available to record accuracy when their phones don’t do it by default. in other words, i bet there’s no actual bug here. it’s probably just a lack of education on this topic, and this thread probably needs to be closed at this point.
