Possibly. Yesterday it was minus 1 here and my s8 was really laggy as I was starting everything up. The phone had been in the bag with the drone and was really cold to the touch. I took off and hovered for a minute or so and all came back to normal and was fine for the rest of the flight. Not sure if it was the phone, controller or drone but it was really laggy for the first 30 seconds or so.
