Try GCam Go, Google’s camera for cheap smartphones
There are numerous ports of the original Google camera app for smartphones of other brands. However, the app doesn’t always work with low-end devices, and this is where Android Go apps can come in handy.
Android Go may be familiar to you, as it is a lightweight alternative to the Android operating system designed primarily for low-end devices.
GCamera Go v3.3 is the latest stable version of GCam Go. The app is now available for most Android Go devices, and it works perfectly on Android devices running Android 8.0 or later.
The latest update comes with everything you need, including HDR+, night mode for low-light photography, and auxiliary camera support (i.e. support of other cameras besides the main one).
The app supports a wide range of devices from leading manufacturers, including Samsung (for both Exynos and Snapdragon chipsets), Xiaomi, OnePlus, Oppo, etc. The app works well with all chips on the market, including Snapdragon, MediaTek, and Exynos.
