With android.hardware.Camera, in order to have the camera output appropriately track the device movement, we need to hook up an OrientationEventListener to the setDisplayOrientation() method on Camera. That way, as the user twists the device around, we can keep what is "up" on the camera preview in sync with what is "up" in the real world. This is particularly true for rotating the device around the Y axis (i.e., flipping from landscape to reverse-landscape or back).
For most orientation changes, the android.hardware.camera2 API seems to "just work". However, for that Y-axis rotation (landscape -> reverse-landscape or vice versa), the camera preview winds up being inverted.
What is the equivalent of calling setDisplayOrientation() on Camera for the Camera2 API, so we can handle this scenario?

Camera2 is the low-level Android camera package that replaces the deprecated Camera class. Camera2 provides in-depth controls for complex use cases, but requires you to manage device-specific configurations. For more information, see the Camera2 reference documentation.
prop in the /system partition of your Android device, you can enable the Camera2 API functionality. First you'll need a rooted phone, and a method of editing your build. prop file. You can either use a root file explorer app (like ES Explorer) to navigate to the /system partition on your phone and open build.
android. hardware. camera2. This package is the primary API for controlling device cameras. It can be used to take pictures or videos when you are building a camera application.
As you've noticed, this is supposed to "just work" for SurfaceView on the camera2 API.
As such, there's no equivalent of setDisplayOrientation().
We haven't heard of this issue before now, so a few questions:
