Hi everyone I was looking for some direction to this issue .  I have a phantom 4 and have roughly 150 flight, not until recently every time I want to fly after it warms up I get a imu error.  I have calibrated it countless times over and over ever time it asked I calibrate.  There are times it will clear itself after it warms up? I don't remember this issue months past since there was a break in the weather I decided to fly.  Any help would greatly be appreciated if it something I am doing wrong or need to do .  Thanks again James.
  

Have you ever had a crash? What do the readings show when your calibration is complete?

Also please help confirm the firmware version for your aircraft.

In that case, would you please try to export the flight log through DJI Assistant 2 when the error showing up.
You can upload it to dropbox and post the link here, we'll analyze that for you.
