I’m hoping someone can help me here. I’ve opened up my brand new Mavic Mini and tried my first hover and flight indoors. After reading everything to the T and following all instructions my Mavic took off and hovered brilliantly I went up to a meter below ceiling level to test the cameras and controls and all seemed fine until I upgradedThe firmware then it started speeding up and crashed into a wall. Everything is dodgy now I’ve tried re calibrating compass and drone but it’s worse now when it rises it doesn’t hover still and flies fast so it’s uncontrollable and keeps going into walls so I have to grab it to stop it. Im afraid to take it outside (poor weather at moment) if it can’t hover and fly easily indoors. Can someone help me or have I got a faulty drone
