Using an old smartphone as webcam/camera recorder.

Hi, here I have and old Huawei P Smart 2019 smartphone with Android 11 that I want to use as webcam; I just open its camera, select video, and after a minute the screen turn black with a line showing "Press the screen for active the camera", but I want that it stay on. Does anybody know how to fix that?
Cheers.

Start by reproducing the reported behavior on the Huawei P Smart 2019 running Android 11, using the camera in video mode as described. Check whether the screen timeout is caused by scrcpy or the device's camera behavior; done means identifying a reproducible cause and documenting a confirmed fix or limitation.
