why tello me when I fly for a few minutes my cellphone screen is dark and I can't control it even though the signal is good and the distance is 1 meter
Try to do fix it by doing they way the video shown. Normally the problem will be solved. If not, it needs to send back to shop for repair if it is under warranty.
@@jinadevbp Tello is imbalance and try to disassemble it to fix the error and build it up again gently, as what I did in the video. If problem could not be solved, you need to send it back to shop/factory.
