Why is it when my Phantom is facing West that my Radar(on the APP) is facing South-East and it shows I am 13.3 ft. up when in fact I am in the house on a table? I would send a picture but when I start a new thread it has no place for me to upload a photo, so I will reply to my own post then I will upload a photo to show you what I mean.

this is my point. thank you all!

The radar also depends on the compass of your mobile device so make sure that the compass of your mobile device is correct.  Also make sure that there are no magnetic or ferromagnetic interferences close by that could throw the compass on both the Phantom and/or the mobile device off.
Altitude is reset every time you power up, however there can be some variance/off-set from zero.  Homepoint will be saved at whatever altitude value was shown when it is saved so not really much of an issue if alt reading is off a bit.

The app says " this phone does not have a compass sensor. Compass functions will be disabled in the program." Is this why my compass is off in the DJI APP?
