 ## Limitations
 
-### Concurrent preview display, video recording, image capture, and image streaming
-
-The CameraX plugin only supports the concurrent camera use cases supported by Camerax; see
-[their documentation][6] for more information. To avoid the usage of unsupported concurrent
-use cases, the plugin behaves according to the following:
-
-* If the preview is paused (via `pausePreview`), concurrent video recording and image capture
-  and/or image streaming (via `startVideoCapturing(cameraId, VideoCaptureOptions(streamCallback:...))`)
-  is supported.
-* If the preview is not paused
-  * **and** the camera device is at least supported hardware [`LIMITED`][8], then concurrent
-    image capture and video recording is supported.
-  * **and** the camera device is at least supported hardware [`LEVEL_3`][7], then concurrent
-    video recording and image streaming is supported, but concurrent video recording, image
-    streaming, and image capture is not supported.
-
 ### 240p resolution configuration for video recording
 
 240p resolution configuration for video recording is unsupported by CameraX, and thus,
