I have a problem. Use DJI Go. The altitude I read is about 4 or 5 meters higher than the real one. What can I do to fix the system?

The video I linked above explains how to work around that issue.I add that it is a bit of time when I start the dji go system makes me wait a bit with the following information: aircraft warning up ... wait to take off
FYI the pellets inside my ultrasonic sensors on the P4 are even more misaligned than yours. One is pointing North and the other South. I Havent had any prominent altitude issues apart from a little bit of height loss/gain when hovering for long periods.Today I made another flight after IMU and Compass Calibration.
Unfortunately, as seen from the photo there is still a discrepancy between the P4 share and VPS.
I then noticed that the pellets inside the ultrasonic sensors are not perfectly aligned in the center as in the photo.
Does anyone have any suggestions?
Do you take off from a different height than where you compare the VPS numbers?Today I made another flight after IMU and Compass Calibration.

Strange!No. I take off from same area and height. The strange thing is that up to a height of 3 meters the data is correct then when I bring 40 to 30 meters and I do fall back I check that at a height of 3 meters from the ground the marks VPS properly while the indication of ' height Phantom marks me at least 5 meters more. This is not good. Imagine doing a mission with waypoint at pre heights what might happen ......
I had noticed something the other day while flying with a friend.. He had a problem right after I armed my Phantom 4.. He was having a hard time getting his landing gear down (Typhoon H) and I left mine idling on the ground for about 4 minutes because he was about to run out of battery and needed to land asap.. About 4 minutes went by and I went back to mine and it had risen about 16 feet in the air according to the app without even taking off.. I repeated this test and it did it again.. My phone has a barometer in it as well with an app for altitude.. It seems to be more accurate than the Phantom 4's barometer, I have tested it going upstairs, downstairs - even over time sitting with the phantom that app did not change altitude by more than 1 foot.. There is a bug in the Phantom 4.. it's repeatable..The altitude is estimated using the Phantom's internal barometer. It's not uncommon for it to be off by up to ~20 feet. If you haven't done so already, try calibrating the IMU.
