DJI Phantom 4 Advanced Remote Controller Back Buttons Replacement

This guide explains how to replace the back buttons on a DJI Phantom 4 Advanced Remote Controller, which shares a similar design with other Phantom 4‑series controllers such as the Phantom 4 Pro and Phantom 4 Pro+. In this repair, you will remove the worn or unresponsive rear function buttons and install new ones to restore full control over customizable flight features. These back buttons allow pilots to trigger key functions—such as camera settings, gimbal adjustments, or custom shortcuts—making them essential for smooth and efficient drone operation.

If your controller’s back buttons feel loose, fail to click, respond intermittently, or no longer activate assigned functions, they may be damaged or experiencing internal wear. Before proceeding, review the relevant sections of your user manual under the troubleshooting section (e.g., “Unresponsive Controller Buttons”, “Intermittent Input or Sticking Buttons”, “Controller Custom Function Not Triggering”) to confirm that the issue is hardware‑related rather than a software or calibration problem.

Because this repair requires opening the controller shell, follow all recommended safety precautions. Power off the controller completely, disconnect it from any charging source, and work in a clean, static‑safe environment. Use ESD‑safe tools to avoid damaging sensitive internal circuitry, and take care when separating parts from the controller to prevent strain or damage on ribbon cables, antennas, or internal wiring. Inspect the device for any signs of battery swelling, cracked housing, or damaged ports, which may require additional attention. Dispose of any broken components responsibly according to local e‑waste guidelines.

For additional background on controller hardware, button mechanisms, or safe electronics handling, you may find it helpful to consult DJI’s official support documentation, iFixit repair guides, or general electronics‑repair resources.
