Incorrect EXIF GPS Longitude #122

I was testing C2PA verification on Android and when checking a photo using https://verify.contentauthenticity.org/ I noticed it was not showing a correct location, just a dot in the middle of nowhere.

Looking at the EXIF data of the photo, the GPS coordinates indeed point to a location in the middle of the sea. After further investigation, this seems to be due to the longitude being inverted.

Here's an extract of exiftool:

Exif GPS Dest Bearing           : 0.0
Exif GPS Speed                  : 0.0
Exif GPS Longitude              : 6°8'54.154" W
Exif GPS Altitude               : 428.9000244140625

The correct longitude for my photo is 6°8'54.154" E. Latitude, on the other hand, is correct.

I tested again with another photo taken from the Proofmode app, and after checking that my phone location was correct in a map app, same issue.

Additional info:

  • Device: Pixel 3
  • OS: Android 12, Build SP1A.210812.016.C1
  • Proofmode version: 2.6.0-RC-2 installed from F-Droid
