Can't take off. The drone must be paired with the remote control before taking off, and the lights cannot flash. Then press the take -off button. 2.App cannot control the drone. When the APP controls the drone, the remote control cannot be connected, and the drone needs to be calibrated. Before taking off, please make sure the indicator light does not flash. 3.App cannot display pictures. Please download the corresponding APP first and connect the drone WiFi. After confirming that the WIFI is kept connected, then open the APP to view the drawing. In addition, the mobile phone system should not be too low or too high, and it is easy to cause incompatibility. If so, try to use other mobile phones.
