First, the video transmission from the drone to the phone connected to the controller failed. The drone was only 30 meters above the ground. The live video on my phone is stuck. After some time, the remote control signal disappeared and the drone stopped receiving joystick commands. He then initiated an automatic return home procedure, but instead of landing in the previously recorded starting position, he simply landed straight down. Luckily it wasn't on anyone's property. This drone has serious connectivity issues.
