Live view blocked by giant black box

We have 2 door cams. Live view works on one. On the other, live view is blocked by a large black box that covers 95% of the screen. The periphery surrounding the black box is quite clear and working well. This happened after recharging the battery and remounting the phone to its fixture on the wall.
