There has been a number of issue with the Mavic Pro disconnecting from the remote controller or DJI Go 4 app. It turned out that the micro SD card in the quadcopter was causing the Mavic Pro disconnects.  Most Mavic pilots will remove the SD Card from the Mavic and plug it into an SD card reader and copy across video etc onto their computer.  However the card can become damaged physically or the file system can become corrupt on the card.
Perhaps the card has been used for something else and has other files and folders on it and when it is back in the Mavic, it causes an issue when you try to record to it. The SD card may still work but it is not perfect and is causing an interference when back in the Mavic.
Take out the micro SD card and try flying and see if you still get disconnects. If you don’t get a disconnect, do a full format of the SD card in a Windows computer.  If it is still causing disconnects after the format,  then replace the card with the DJI recommended SanDisk Extreme micro SD Card 64 GB.

Why are you stating all these posts as facts when they are not true?  I have been flying for years and never experienced any of the causes you mention for disconnects.  The remote signal has nothing to do with the SD card.  

You have posted 7 posts, all on the same subject, and all with wrong or unrelated information about why disconnects occur, which in 99% of cases, is simpley poor signal due to external radio interference, long distance, or poor orientation of the remote antenna.

Disconnection between the AC and RC is caused by obstructions in the environment, interference from WiFi sources and electromagnetism in the environment and more basic issues like a loose cable or flying too far away. The SD card malfunctioning may lead to files being corrupted but will never cause an RC or app disconnection. I appreciate the effort you a have taken to create a multitude of tips on what must be nearly 20 different threads now but do ensure that you yourself know what you are advising on. Unlike most forum users who have been flying for years, there are some that are new to the hobby like yourself who will read your posts and act on them. If the information you give out is inaccurate it may lead to bigger issues down the line and even flyers crashing by being misadvised.

Then read the Manual a few times.
Posting nonsense like you have been doing do not help anyone.
There are people which come here looking for advice and help and they do not deserve this BS.

Many beginners visit this forum to seek advice from DJI and experienced pilots.

As a 'first timer' it might be easier to sit back and learn instead of cutting and pasting poor advice (crap) and then go fly to know what you are talking about

Read your manual. I don't see any drone avatars under your profile

Are you even flying drones or just trolling for points or are you here to just state untrue facts?

Woe and others,
I will ignore his posts in future,
He seems to be attention seeking.

Seems logical and all the replies to this agree that a corrupt SD card cannot cause disconnection problems. I feel the same way. Except, I experienced this very same issue yesterday with my M2P. Had my normal Lexar 64GB card installed, have used this same card many, many times in this drone. Powered on drone after powering on smart controller. Connection kept dropping and display showed many strange errors like IMU error, cannot take off. I removed the SD card and restarted, switching to internal storage. The problem went away. I tried a Sandisk 64GB card, and there was no issue. Tried the original Lexar 64GB, and the issue came back. I tried formatting it in the drone and still had the issue. I know this sounds like nonsense, it's not. I am not a super-experienced pilot, but I have at least a couple hundred hours flown. I am familiar with most issues and know how to fix them. I guess it's possible a corrupt card messes with the software or maybe creates radio interference. I don't know where the OP posted in other threads, just found this one on Google, but I can at least confirm this issue exists and is not some newbie mistake looking for attention.
