LR Mobile app suddenly malfunction as camera, Samsung Galaxy S10

This occured first a few days ago. I have uninstalled and then reinstalled the app, the problem persists. Last sunday I used the app to take the photos in raw format. All fifteen something photos turned out equal, except some were shown in portrait mode and some in landscape. Today I repeated the session to see if the problem was solved by itself, but no. Every time I take photos with different scenes, the first scene is repeated on the subsequent photos. When I close the app, or leave the camera setting, and then restart the camera on the app, the problem is repeated, the first scene is repeated onto the next photos as identical copies, however with different time stamps and sequential numbers. Strange. which is the primary suspect, the LR app or the phone? The standard photo app functions as normal.
