DJI Phantom 2 Vision Losing Control During Flight

If your DJI Phantom 2 Vision drone is unresponsive to controller input or shows abnormal movement, follow this troubleshooting guide.

The Phantom 2 operates at a maximum distance of 1km, with a maximum height of 400 ft. Traveling at maximum range may cause buffering and latency. Exceeding this range may cause the drone to lose signal to the controller.

• In the Phantom 2 Assistant, you can set the max distance and height. Using this will help you set a range for the device, which in turn should not allow it to go passed its maximum parameters.

-10°C ~ 50°C is the optimal temperature the device should stay at, being outside of this range could cause a host of issues including signal loss or latency.

• If you notice this in flight, don't Idle. Instead, try to continue to move, this is because while moving, air circulation will be much stronger and cool down the device.
• If the device is not in motion and landed, turn it off and let it stabilize the temperature of its internal components for at least 15 to 30 minutes.

If strong signals on the same frequency are in the range of the device, this may cause it to lose connection to the controller.

• Use this link to the GEO Zone map on DJI's website or find an alternate Geo Zone map on an alternate platform. Using this will ensure the area you fly in will not be restricted or have other complications such as interference.
• Make sure no large buildings or other infrastructure are obstructing the drone's path.

If the firmware on the drone and the controller are different versions. The drone will not connect to the controller.

• Link the drone to the controller and check for updates on the DJI fly app. If needed message will display to update the firmware
• To update the process, start by connecting to the internet, and then by tapping the update prompt. Then hit “Start Update” and don’t turn off the device until “update Success” is shown.

• If the device loses power, it will also lose its signal. If the device cannot power on and off, there are other issues other than signal loss.
• Ensure the device can be powered on and has adequate battery power left.
• Make sure the battery and battery compartment are not damaged or blocked in any way from connecting.
• It could be a faulty battery, so make sure to try to test two separate batteries for quality control and performance with your device. Replace the battery if necessary.
• If the device powers down despite sufficient battery life, it likely has internal component issues. The main circuit board or motors may need to be replaced.
