How to Enable Camera2 API on Any Device: Step-by-Step Guide

Camera2 API unlocks advanced camera features on Android devices. It improves photo quality, manual controls, and RAW capture. This guide shows you how to enable it and check if it’s active.

Check If Camera2 API Is Enabled

Before making changes, confirm if your device already supports Camera2 API:

1. Use the Camera2 Probe App

• Download “Camera2 Probe” from the Play Store.
• Open the app.
• Check the “Hardware Support Level” result:
  • LEVEL_3 or FULL: Camera2 API is enabled.
  • LIMITED or LEGACY: Camera2 API is not fully active.

1. Manual Check via ADB (No App Needed)

• Connect your phone to a computer.
• Install ADB tools on your PC.
• Open Command Prompt/Terminal and type:
  adb shell getprop persist.vendor.camera.HAL3.enabled
• If the result is 1, Camera2 API is on. 0 means it’s off.
