Asus Zenfone Max Pro is budget beast and recently they launched a 6GB variant with an improved camera. But the only problem with this device is its camera. Well, it’s not bad but UI of the camera sucks and also Camera2API is not enabled.

What is Camera2API?

Camera2 API is a lot and better to search for. Nutshell, faster camera, ability to capture RAW photos (photos you edit in software as a pro photographer), high bitrate and high frame rate video recording, and overall better access to the image sensor for apps. If you were thinking of the camera as a video game, Camera2 API just brought Android to level 99 from level 1.

Enable Camera2 API without unlocking Bootloader: 

  • setup fastboot and ADB drivers on pc
  • power off the phone and enter fastboot mode.
  • fire up fastboot terminal and connect your phone to the pc, enable USB debugging mode from dev. options too.
  • Run the command:
    fastboot oem enable_camera_hal3 true 
  • reboot
  • check g cam or any camera API testing apps to make sure if it’s working.

Here is a video guide if you don’t get the steps.
