What to do if the Mavic 4 Pro doesn't respond to controls after takeoff: If the DJI Mavic 4 Pro doesn't respond to controls after takeoff, it indicates a serious problem that requires immediate attention to avoid a total loss of control. The first step is to see if the DJI Fly app displays any error messages, such as loss of signal between the drone and remote controller or electromagnetic interference. In some cases, the lack of response may be due to incomplete pairing between the two devices, which can be resolved by shutting down and restarting both the drone and the remote controller to reestablish the connection.

Another likely cause is a failure to calibrate the remote controller's sticks, causing commands to not be correctly recognized by the system. If this is the case, the pilot can attempt to land automatically using the RTH button or wait for the drone to trigger an emergency landing due to low battery. It's also possible that the drone is in Intelligent Flight Mode or Automated Recording Mode, where certain manual controls are temporarily restricted. Checking which mode is active helps rule out operational errors by the user.

If the lack of response occurs during an automated flight, it is possible to force the function to be canceled by holding down the pause button on the remote controller or tapping the "Stop" option on the screen. This can return full control to the operator. However, if the loss of response is complete, and even automatic commands are not working, it should be assumed that there is a critical failure in the communication system or sensors, and the drone should be allowed to land autonomously in its current location, avoiding movement until the problem is resolved.

This type of situation reinforces the importance of performing a complete pre-flight check, including proper controller pairing, stick calibration, and reviewing the active flight modes. Loss of control may seem like a catastrophic failure, but with technical knowledge and quick action, it is possible to recover operation or at least avoid damage. The DJI Mavic 4 Pro is equipped with safety measures that reduce risk, but it is the operator who must be prepared to intervene judiciously and quickly.
