CameraX / Camera2 – Autofocus locked on previous scene causes wrong focus when quickly changing scene and capturing

Share

I’m using CameraX (Preview + ImageCapture) on a Samsung Galaxy Fold 7.

My current flow is:

  • Let the camera autofocus and become stable on one scene
  • Quickly move the camera to a new object/scene
  • Capture immediately

Problem:

  • Autofocus is still locked or focused on the previous scene
  • The capture happens before refocus completes
  • Resulting image is out of focus / wrong focal plane, affecting image quality

Questions:

  • Is this behavior expected with CameraX / Camera2 autofocus?
  • Is there a recommended way to force refocus or reset AF when the scene changes rapidly?
  • What is the best practice to balance AF locking vs fast scene change to avoid capturing with

That's a common issue with CameraX! It's like playing Wordle Unlimited – you need to quickly adapt to a new word (scene), but sometimes the autofocus is stuck on the previous guess (focus). Is there a way to instantly clear the "board" (reset AF) before taking the "picture" (capture)? Understanding if this lag is standard or if a workaround exists is key to sharper images.
