Losing control of drone with correct setting

[Phantom3News]

Just went out to fly to take photos of the sun set due to all the bad weather we had over the past few days. Return home attitude set 100m and I was flying at 50m distance was only 175 feet and my drone started spinning in circles. Went north, south, east, and west. Fighting to control it ! Then I hit RTH and it still continued. Only way I got it back home was to fight then I landed hard right beside the car in my drive way. Wind 7 mph and this has never happen to me. However I was using my iPhone 6s Plus which I never fly with because sometimes the screen locks up. Any help will be appreciated. Only puts a small crack in the housing. Please help

Sounds like a bad compass calibration.

Can you post the logs?

Flight logs will definitely help us getting into more details.

Start with checking RC calibration specially yaw stick movement. You can recalibrate it.

Also check if you see any visual issue with motors/ props on any one side.

Just looked over the entire unit and don't see any damage, I landed in grass so it wasn't that bad. However I have 3 of these units the standard, advance, and the the professional. Don't want this to happen again,
