Altitude holder problems

I tried to move my flight mode to Altitude holder when I was flying but when I around 2 meters from the ground the drone tries to land.
When I give some more power to adjust the altitude, the drone jumps like there is a bad reading of the sonar but I checked the logs and it seems to be good.

Do I have too much noise on the accelerometer ? Do I need to tune the altitude PID ?

Flying in stable mode is good

no answer from the diydrone :frowning: I dont know what is wrong…

did you try to set the middle throttle? I had around the same issues but I have resolved with the attached procedure.
