With the Android 4.2 camera app, how can I tell if I have a GPS lock? My Galaxy Nexus has just been updated to v4.2 of Jellybean, Google seem to have totally changed the camera app in this update and there's a few functions that I just can't find.

As I'm travelling a lot at the moment, I like to make sure that most of my pictures are geo-tagged so that I can work out where I was and when later! As I'm not in my home country, I have data disabled to save on extortionate roaming charges, so most of the GPS-Assistance functions don't work and GPS locks take longer than normal.

Previous versions of the Android camera app have had a small icon near the top of the screen in the camera app that flashes to indicate that the GPS is searching for a lock, that then turns solid when a good GPS lock is achieved. There doesn't seem to be any similar icon in the built-in camera app in the stock GED version of 4.2.

Is there any way that I can tell if the camera has achieved a GPS lock before I take a picture?
You can press the right soft-key (switch application soft-key). The application switcher in Android 4.2 includes the notification bar, which shows if there´s a GPS fix. You can press the right soft-key again to return to the camera app.
