* A quirk to denote the {@link android.hardware.camera2.CameraCaptureSession} cannot

*
* <p>QuirkSummary
* Bug Id: 146773463
* Description: Opening and releasing the capture session quickly and constantly is a problem
* for LEGACY devices. It needs to check that all the existing capture sessions
* have finished the processing of their capture sequences before opening the
* next capture session.
* Device(s): Devices in LEGACY camera hardware level.
