Ok so here is my horror story with DJI so far. Got a phantom 3 pro, was great everything worked awesome. The return to home button fell inside the remote after 1 flight testing out all the features. Exchanged it at bestbuy the new one I tested out of the box before even unwrapping it same thing button was inside the remote just barley pressing it. I fully returned it. Went and got a phantom 4 yesterday updated all the firmware it wanted me to. Go to fly it and it keeps saying compas error. It won't calibrate no matter where I go or what I do. I did fly it at a low altitude for a test and flew fine. It also says (I took a screen shot) hardware error contact dji for repairs. This would have been the third phantom product I got that I will be exchanging. Should I exchange it or hope for a update to fix this?
