Enable Camera 2 API in Build.prop

It is one of the perfect methods to enable many of the hidden Android features in smartphones. You can enable the Camera API 2 also using the Build.prop.

  2. Navigate to the system partition in your rooted Android phone and find the file named Build.prop.
  3. Open the Build.prop file using the text editor.
  4. Inside the Build.prop file, search for this line:
    persist.camera.HAL3.enabled=0
  5. Change the 0 to a 1, then save and exit the Build.prop and reboot your phone.
  6. You can then check if it worked by launching a third-party camera app like Open Camera.build.prop

Enable Camera2 API with Terminal Emulator

If you are having bad luck with the first method, you can try this second method which is more comfortable and includes zero complication. Remember, you will need the root access on your phone to do this. Follow the steps carefully:

  1. Download and install the Terminal Emulator app from Google Play Store.
  2. Open the app and run the following commands:
    su
    
    su persist.camera.HAL3.enabled 1

How to check if your Android smartphone supports Camera2 API

  • Install the Camera2 API Probe App
  • Launch the app, and look for two sections — Camera ID: 0 and Camera ID: 1. The former is the rear camera while the later is for the front camera.
  • Under Camera-ID, explore a subcategory with the name “Hardware Level Support Category.” That’s where you can figure out the Camera2 API support level on your phone.
  • For your phone to support Camera 2 API, you need at least Level 3 or Full. If that’s the case, then Camera 2 API is enabled for you.

If you see a green tick next to Level 3 or FUll, then it means it is enabled. Read full details here.

Levels of Camera2 API

There are four levels of Camera 2 API or rather Hardware Level Support Category (Camera 2 API Hardware Support Level)

  • Level-3 – Apart from FULL, the OEM has added their customization, has included features like RAW, Pro mode, etc.
  • Full – The camera on the smartphone supports all significant capabilities of the Camera2 API.
  • Limited – The camera supports only some of the features of Camera2 API.
  • Legacy – The phone only supports the Camera1 API features.

The difference between Camera 2 API level 3 vs. full is huge. OEMs can offer a lot of features on top of Camera 2 API to take it one step further like by adding YUV reprocessing, RAW image capture, and more.
