Of late, I found that, If a photo is shared over Whatsapp, the Geotag is lost. I guess, WhatsApp removes it in order to compress the image so as to reduce the size.
Many Android users use third party software to Geotag the photos. These software impose the location on top of the photo like a watermark. Actually the Geotag Location information is stored internally as extra information in the image. Those software just impose that location information on top of the photo just to give an impression to the ordinary user that the photo got geotagged. However these software MAY be harmful because you dont know what all permissions you have allowed while installing it.
The trouble comes, when the photo is shared over Whatsapp. Whatsapp simply remove the Geotag Location information (EXIF data) when shared as a photo. The location information imposed by those third-party software as a watermark on those photos are still visible when shared over Whatsapp but technically those photos are NOT geotagged.
How to Geotag safely and effectively
You really dont need any third-party software to Geotag a photo.
1. Just enable Location/GPS in your phone
2. Also enable Location in your Camera app's settings. Dont worry if such option is not there in your phone.
3. Take the photo.
4. Do not share over Whatsapp as a photo. If you do so, the location information is lost. However you can share it as document in Whatsapp.
5. You can transfer the photo using phone cable, Email, Bluetooth, Wifi-Direct etc.
In few of the gallery apps, you can find the location of the photo in the details view. Alternatively you can use this service http://exif.regex.info/exif.cgi to check if the photo is geotagged or not.
