Google Pixel smartphones aren’t known for their advanced camera hardware. However, they are pretty much known for its advanced camera application that can do wonders with simple hardware. Google’s set of algorithms for the camera app is the holy grail of smartphone cameras. Exclusive features are coming with it like HDR+, Astrophotography that made it stand against the competition. Due to the wonders brought by this application, the community flourished with custom ports of the app named Gcam. There are multiple variations of the app offering a wide array of features and extensive support for several Android smartphones.
Today, we are going to teach you how to install a powerful MOD inside the Gcam community. It is named UltraCVM and offers HDR+ modes, Astrophotography as well as a wide variety of controls to improve the image quality. However, the mod seems to support only Android 10 and Android 9 Pie devices. It’s a limitation from the GCAM 7.3 base.


In short, Gcam is a mod that aims to bring the Google Camera app to several smartphones and ensure that all features work with them. There are several variations of Gcam. Some are meant for multiple Android devices, while others are made specifically for a single smartphone. Multiple developers are working on Gcam and we have today an active community of users using the Mod.
The new mod is a complete rework on the GCAM 7.3 base. It was made by the developer UltraM8, and all credits go for him and the community behind the GCAM project. It brings a new design and advanced features. If you’ve some knowledge in image controls, you may be able to capture stunning photos with your smartphone. However, you can simply install the app and most features will be available at startup.
