I have a MAVIC AIR (firm 0400) + iphone 7 Plus (iOS 11.3.1) + DJI GO 4 (4.2.14)
After updating the firmware + software, the video preview images by the remote control have an incredible lag, regardless of whether you use any 2.4 or 5.8GHz channels.

I posted some videos on this topic:

https://forum.dji.com/forum.php?mod=viewthread&tid=147692&page=1#pid1349673

The strangest thing is that this does not happen when I connect MAVIC AIR directly to the phone's wifi (without using the remote control). The preview images look perfect. Just connect directly through the remote that lag back.

Does anyone have any suggestions?

I've this terrible lag in dji go since version 4.2.8 (android)

Furthermore I've also minor lag in videos recorded in sdcard (SanDisk extreme pro 64gb)

Thank you for your help.
Just to update, it seems to me that this problem has something to do with ISO, Shutter or image processing (more light or less light).

Low light environments (even when in AUTO) cause more Lag in the drone movements (Yaw or Gimbal)

Some idea when DJI will launch new firmware ????
I´m going crazy to try roll back to 300 (with third-party soft, if you understand me)
