@KanwalKhan-20 Can you tell the cpu's of the phones you were using? It seems like the MediaTek processors have this issue with android 11, 12.

@KanwalKhan-20 have you tried to change the format, maybe the webcam is MJPEG? Or you already had it working on other phones?

Well I don't know exactly which example or whatever you're using. I don't remember exactly regarding the examples but if there are settings that you can change from the app interface try to change them. In code however, find the UVCCamera object. Then in it's method "setPreviewSize" try to change the third argument to either FRAME_FORMAT_MJPEG or FRAME_FORMAT_YUYV. Also try to change the resolution in the same method.
