thomas123,
Thanks for the heads up on the exiftool -v5 option, most useful!!
Looks like Flir has added some new tags and another GPSInfo SubDirectory:
| | FLIR Record 0x2b, offset 0x1b730, length 0x00b8
| | 6) GPSInfo (SubDirectory) -->
| | - Tag 0x002b (184 bytes):
Lat & Lon references as ascii chars N/S E/W at offset 0x09 & 0x0b.
Latitude & Longitude as double precision floats at offset 0x10 & 0x18.
Room for other info as well, total of 184 bytes.
using exiftool -v5 <filename> I examined the 2 areas of GPSInfo in the following 3 images:

FLIR0002_sample.jpg has a creation date of 5/16/2014 shows a GPSLongitude of E 18 in Flir Tools Mobile.
The normal GPSInfo tags also show E 18 and the sign of the double float is + in the additional Flir gps data, which is correct.
Lat & Lon ref in the additional Flir gps data are correct.
Both GPSLatitude & GPSLongitude Tags are present in the normal exif GPSInfo section.
I don't have any early samples from W Lon or S Lat so it's hard to know what Flir Tools Mobile would show.
IMG_1854_untouched.JPG has a creation date of 7/2/2015 shows GPSLongitude of W 82 in Flir Tools Mobile.
The normal exif GPSInfo tags shows the same, BUT the sign of the double float is + in the additional Flir gps data which should be -.
Lat & Lon ref in the additional Flir gps data are correct.
Both GPSLatitude & GPSLongitude are present in the normal exif GPSInfo section.
flir_20150908T144845.jpg has a creation date of 9/8/2015 shows a GPSLongitude of E 107 in Flir Tools Mobile which should be W 107.
The normal exif GPSLongitudeRef tag correctly shows W. The sign if the double float is - in the additional Flir gps data, which is correct.
Lat & Lon ref in the additional Flir gps data are correct.
The GPSLongitude Tag is missing from the normal exif GPSInfo section.
I conclude that Flir fixed the sign problem between 7/2 and 9/8, BUT Flir tools Mobile hasn't caught up, AND Flir
messed up the normal exif GPSInfo section by leaving out the GPSLongitude Tag.
So there are issues in both the Flir One App, and in Flir Tools Mobie App (for Android).
Please refer to the gps.txt file that is attached that shows the details of the exiftool data dumps.
also are attached screenshots of the Flir Tools Mobile info screen for each of the image files.
