I was having the same issue with my new drone. I spend few hours researching and I found out that you have to put phone in Airplane mode, then turn on WiFi. Once I did that, error message went away and I was able to calibrate.I'm having the same issue though mine is IOS. It keeps saying "insufficient Power To Calibrate Compass" even though it's fully charged, I just got this product yesterday. I'm on hold for an hour trying to contact the company and my current wait time is "2 Hours" LOL
