My Samsung Galaxy Grand Duos is not embedding GPS information(Latitude/Longitude) in Photos taken from the phone camera. I have enabled GPS option in main settings, and also set the GPS tag in the camera settings. The latitude and longitude information is not appearing in the photo details. I do not wish to enable the "Mobile Data" option. I do not need the location information like place name, etc... I only need latitude and longitude information. What other setting am I missing?
It could simply be that the phone doesn't have a GPS fix when you take the photo. It might be different in your phone's camera app, but most camera apps start asking for the position when you start the app, and if there isn't a fix when you hit the 'shutter release', they save the photo anyway, rather than holding you up waiting for a GPS fix. Getting an accurate position can take some minutes if you're hidden from the sky, so it's easy to take the photo first without realising.
Check the location icon in the notification bar, and be sure it has stopped blinking before you take the photo.
