How Do You Enable Camera2 Api on Any Android Device?

If you want to install the Google Camera port on your Android device, enabling the Camera2 API is essential. This API upgrade can significantly enhance your camera’s performance, allowing you to capture stunning photos and videos effortlessly.

But what if your phone doesn’t support the Camera2 API by default? Don’t worry, we’ve got you covered. This guide will walk you through various methods to enable the Camera2 API, ensuring your phone can take full advantage of advanced camera features.

Before we dive in, let’s clarify some key terms and prerequisites.

This API offers a range of features designed to improve camera performance, including better HDR+ capabilities and enhanced low-light photography.
