Below are a couple of tips on using the camera on the Samsung Galaxy S7 and S7 Edge.
1) After opening the camera app, select modes, and then tap Download. This will open another page where you can download another camera app. I would suggest downloading Surround Shot.
2) With all the camera modes on the screen, if you tap more, add a shortcut to the home screen, you can tick the modes you would like to appear on the home screen, and hit save. Camera mode shortcut icons will be added to your home screen. This will happen even if you use Nova Launcher.
3) I mentioned downloading Surround Shot mode. With this if you photograph 5-6 shots you can recreate the wide angle look similar to the LG G5. Panorama mode is also good for a super wide shot. Obviously, it is not as true wide angled as the G5 in effect, nor would it work very well with moving subjects.
So have you got any specific tips ?
