Ive recently purchased the s21 ultra and love the camera and was thinking of using it for work. I work for an estate agents and have ordered a tripod for the phone, but I was thinking is there a way to remotely take a photo without me being in a room (whilst the phone it close up against the corner of a room). I don't mean me waving or palming the cam then running off but more maybe control it from another phone so using that as a view finder? Or maybe some other device like a clicker but definitely would prefer a way or remotely seeing the cameras view so I could change settings in Pro Mode whilst it's set up in its position.
