Bugs B4W Body Removal

Hello, very new to drones. I recently purchased a MJX Bugs B4W foldable drone. When I received it and tried to insert a SD card, it felt like the card holder moved, now the card will not stay in, it doesn’t lock in place. If anyone could tell me, how do you remove the main top body (plastic) so the I can get to the camera and card holder? The seller has offered me a partial refund to have this fix myself. And saves me from shipping back and forth. Thanks for any advice… Randy

OK, after researching for hours, I found an answer. On the bottom of each arm is a removable pad. A little slot on each corner to pry up and remove the pad, under each pad is 2 screws. Removing those 2 screws from each arm, then just wiggle the top plastic off to reveal everything. A pic just in case anyone needs the same info some time. Perhaps a newbie like me…
