I’m having an issue with my DJI Mavic 2 Pro. It keeps disconnecting during flight. I’ve read through countless online forums and tried many things before posting this here.

When flying, I see the following errors even with the drone is very close by and in direct line of sight.

• Warning: “Weak signal. Adjust antenna and avoid signal block.” (Screenshot: https://imgur.com/KjnKQVe)
• Warning: “Adjust antenna and avoid signal block.“ (Screenshot: https://imgur.com/YwBXPZL)
• Error: “Weak Image Transmission Signal. Adjust antenna.” (Screenshot: https://imgur.com/h6hKz4L)
• Error: “No Image Transmission Signal.” (Screenshot: https://imgur.com/G40KBjp)
• Error: “Aircraft Disconnected” (Screenshot: https://imgur.com/xh48dh2)
  

Whenever this happens, I still have good remote controller signal strength (usually 4-5 out 5 bars) and can control the drone even though I don’t see anything in DJI Go App. The image transmission signal usually shows as 0 out of 5 bars when the issue happens).

I’ve read through many online forum posts, so these are all the actions / diagnostics things I’ve tried so far.

• Ruled out my Phone as the problem.  This first happened to me back in October using an iPhone 11 Pro Max, but I recently upgraded to an iPhone 12 Pro Max and the issue still occurs the same.
• Ruled out the wire as the problem. I don’t believe the issue relates to the wire connecting the controller to my phone. To rule out the wire, I used a USB-A to lightning wire instead of the DJI wire and the same issue happened. (Image: https://imgur.com/Bi7L9I8)
• Relinked the controller / drone. Successfully relinked using instructions in this official DJI video: https://youtu.be/HUVwvfIdnXA
• Reformatted the MicroSD card. I read on some forums that some issues with the microSD card can cause these issues, so I completely reformatted the card. I also tried flying without a MicroSD card in the drone. These did not fix the issue.
• Calibrated the IMU
• Latest firmware. ensured both drone and remote are on the latest firmware.
