Hi thanks for reaching DJI Forum, apologies for any troubles you are having. May I ask what is the mobile device you are using to run the app?

iPhone 7plus

Hi there. We apologize for the inconvenience. Can you upload the video?

Are you using the AutoTakeoff ? Try using the Remote Controller's Sticks for Takeoff.

Try to watch this Buddy -

Do you have an RC?
If yes, as in the linked video above mentioned, don't "slidestart" it from the app, but use the RC stick, very slowly to get it in the air.
That worked for mine for quiet some flights.
In case you have a RC, you have a sec. battery, assumingly. Is it behaving the same with every battery?

Same problem here. I don't want an alternative to launch. It can get it in the air but you still have to land. It's not pretty. Need a fix

Hi, sorry for the inconvenience, I would like to ask if you manage to calibrate IMU and compass of your aircraft? Have you tried to check as well the GPS signal if it's strong or not? Please ensure that we're getting 18 or more satellites for us to have better flights as well.
