Before using the Google Camera HDR+, you have to enable Camera API 2 in the MIUI, unless any version of Google Camera you install WILL HAVE NO HDR+ EFFECT OR CRASH AFTER OPENING!!!
The way I choose to enable Camera 2 API on MIUI is through the Magisk platform, and there are 4 steps of prerequisites to get to this:
- Unlock the bootloader
During the process, you will also need to install the driver in computer for your phone.
- Flash the 3'rd party recovery, like TWRP
Also download the Android platform tools, unzip, and open CMD on windows or terminal on macOS and cd (move) to your unzip directory.
After that, flash the TWRP recovery into your phone.

- Flash the Camera 2 API enabler
Flash the zip to enable enable Camera 2 API.
You can check whether you successfully enable the Camera 2 API by Camera 2 API probe:
