Had as well a lot of times that problem, also cannot turn phone, how I fixed.....I connect the phone to the rc and then i do phone compass calibration ( before i put the rc on)..... works all the time perfectly!
Give it a try
Tnx tried it many times
About half times it helped but not always.
For me it's interesting that before February I didnot get such problems.
But it was a couple of phone firmware version ago and drone also and DJI fly to.
So could not tell when it was broken.
I bought drone at January and had no problems with radar until February (or March maybe)
