GCam XML config file download helper
Gcam Config: Xml File is a free utility application by a developer named Wriink. It is an information database and download tool that can help users find and acquire XML config files for the popular camera app, GCam. Through it, they can browse over 20 different models and configurations to determine which one works best for them.
Ports and config files
The Gcam Config: Xml File app is basically a database wherein you can check all the available XML config files for various third-party GCam ports available to Android devices. There are currently over 20 models available in the app, and you can check which one will work best with your device. Once you've found one, it will then provide download links from external sources to get it.
Depending on the file you choose, you can expect to see different features enabled(if natively supported) and different processing algorithms to achieve the distinct "pixel" look that Google's smartphones have been known for. Now, given the experimental nature of these ports, they're not guaranteed to work on your device. This is one of those trial-and-error cases wherein you just have to try them out first.
For GCam port users
If you're a non-Pixel phone user and still want to experience what it's like to use its camera app, then GCam ports are your best bet. Think of the Gcam Config: XML File app as a complementary tool to help you find the best version and configuration for your device and ensure you have all possible features enabled and shots coming out the way they should.
