Samsung S7 / Seek app version 2.2.2 (46). I selected a plant photo from a previous day’s outing in my phone’s gallery and added it to Seek. I then chose to upload it to iNaturalist to try out that feature. A little while later, I checked iNat and noticed that it had taken my current location from when I added the observation. Turns out the photo I used had no GPS coordinates attached in the metadata. This publicly revealed the location of my home. Oops!
I went to take a screenshot of the image metadata to show how no location was attached, but the photo I used no longer appears in my photo’s “Camera album”. I checked an image I took at the same time/place, and the photo details say “no location”.
Anyway, looks like any photo that lacks a geolocation that I upload to iNat via Seek will automatically grab my current location at the time of upload.
