Code 1: DJI Phantom 4 Blinking Red Light.

Usually, DJI Phantom 4 indicator LEDs blink red because of low battery power. Therefore you need to charge the Phantom 4 aircraft battery fully or to a sufficient level.

Code 2: DJI Phantom 4 Blinking Yellow Light.

If your Phantom 4 aircraft LEDs blinking yellow, that means the aircraft needs to be linked to the controller.

1. Connect the mobile device to the controller and power on the Phantom 4 controller and aircraft.
2. Open the DJI GO app and go to camera view, click on three dots on the top left corner and click on the RC icon.
3. Then scroll down and click on the “Linking RC” button and hit “OK”.
4. Once you have done that, find the red flashing circular hole between the USB and SD card slot and press it using a pen or suitable tool.
5. Then the controller would be linked to the aircraft and the aircraft would flash green.

Code 3: DJI Phantom 4 Flashing Red And Yellow.

If your Phantom 4 indicators keep blinking yellow and red, that means the Phantom 4’s IMU or compass is miscalibrated and required calibration.

Solution 1: Calibrate Phantom 4 IMU.

1. Remove aircraft propellers and turn on the aircraft.
2. Connect the Remote Controller to the mobile device.
3. Open DJI GO 4 App and go to Main Remote Controller Settings > Advanced Settings > Sensors.
4. Then tap Calibrate IMU.
5. Place the aircraft according to the demonstration on the DJI GO4 app. Once all the positions are calibrated the IMU calibration is successfully done.

Solution 2: Calibrate Phantom 4 Compass.

1. Bring the Phantom 4 Compass Calibration process outdoor where away from dense woods and buildings.
2. Remove the propellers before you start the compass calibration.
3. Open the DJI GO 4 app and tap on the Aircraft Status Bar and select “Calibrate”.
4. Then hold the Phantom aircraft as demonstrated on the DJI GO 4 screen.
5. Hold the Phantom 4 aircraft horizontally and rotate 360 degrees. Phantom 4 status indicators will flash solid green light when it’s successful.
6. Then hold the aircraft vertically, with the nose pointing down, and rotate it 360 degrees around the center axis.
7. Once the compass calibration process is successful, the status indicators would flash green.

Code 4: DJI Phantom 4 Remote Controller Blinking White.

Usually, DJI Phantom 4 controller indicator LEDs flash white to indicate the battery level of the controller. But if your controller’s first indicator LED flashing white and beeping even while it’s connected to the charger, that means the remote controller’s battery is faulty. So you have to replace the Phantom 4 remote controller battery to solve the problem. Check out the below video to know how to replace the battery.

Code 5: DJI Phantom 4 Remote Controller Blinking Red Green.

As reported, many users face DJI Phantom 4 controller blinking red and green issues after updating DJI Phantom 4 firmware. Therefore this issue must be a result of a firmware glitch. Most of the time, firmware upgrade glitches are caused by performing the firmware upgrade process through DJI GO 4 mobile app. So it’s advisable to upgrade DJI Phantom 4 firmware using DJI Assistant 2 PC application.

Solution: Revert /Upgrade the DJI Phantom 4 controller and aircraft firmware using DJI Assistant 2.

Code 6: DJI Phantom 4 Battery Blinking 16 Times /DJI Phantom 4 Battery LED 4 blinks three times per second.

In most cases, the DJI Phantom 4 battery blinks 16 times, because of high temperature of the battery. Actually, 16 times of indicator blinking indicates that you need to cool off the battery before you put back it to the charger.

If you left the Phantom 4 inside a closed warm place or flew intense in sports mode, the battery should have exceeded the proper temperature range and you need to cool off the battery before you plug it into the charger. Leave the battery in airflow to cool off and then plug it to the charger to solve the problem.
