I just received a replacement P4A from dji and after take off the altitude is way off and sometimes just sticks at a number and stays there and when flying it loses and gains altitude ive calibrated everything and refreshed firm ware .
I don't remember my previous P4A doing this ,any one experiencing this .and or what is the fix.

Check the downward pointing censors. Make sure their not covered with plastic or blocked in any way.

Sometimes those come out of the box with protective plastic coverings that are very easy to peel off. Those little thing majigs measure air pressure so the drone knows its altitude.
