Cannot read GPS Coordinates after "Take Photo" option

Hi!
I created app to read Geo Location using exif_read_data function.

Code:

---

$info = exif_read_data($file);
 if (isset($info['GPSLatitude']) && isset($info['GPSLongitude'])) {         
                    $GPSLatitudeRef  = strtolower(trim($info['GPSLatitudeRef']));
...................................... and so on
}

---

I used iPhone 6 to take a picture and upload it using my app.

Scenario 1:
I took a pic
Opened app to upload a file
Selected (from "Photo Library") - got coordinates!

Scenario 2:
Opened app to upload a file
Selected "Take Photo" - no coordinates! :-(

Does anyone knows why?

Thanks,
Alex
