Just today Google released, together with Samsung, the Google Play Edition Galaxy S4
. This is a fully stock Android powered Galaxy S4, just like the Nexus series. It has none of Samsung's proprietary software though, just pure Android.
One this that was introduced though, different from the Nexus 4 that runs the same stock Android 4.2.2, is a new stock camera app. The camera app from stock Android 4.2.2 contains Photo Sphere, Google's 360 panoramic photo mode, and was improved with a new settings mode that allows you to select the flash mode and other settings with a flick. Another important feature that was added is that the volume buttons now act like a shutter button. The S4 is not equipped with a special button to take photos, an so are most Samsung devices, but with this option you can easily take pictures by pressing the volume buttons.

Luckily, a developer was able to extract the app from the system and port it into an APK. This means that you can download and install the camera app on your Android device also. Just download the photo sphere camera app from one of the following download mirrors.

Place the APK on the SD card and install it like a normal apk. This means you have to enable 'Unknown Sources' from Security Settings. Know that the installer will add a new Gallery App and Camera App on your phone.
The app was test on many Android devices running ICS and JB, but there might be some devices that the app cannot be installed on. Give us a hint if you didn't manage to simply install the camera as an APK.
