I wonder if anyone else had this issue. I have Xiaomi Redmi Note 3 with DJI Go 4.1.0, also tried 4.0.5. In the end of first set up of my Mavic I get message "Failed to set. Check the connection between DJI device and mobile phone. Error code: 235."
Didn't find anything in google, also heard that Redmi Note 3 works fine with DJI Go.

Actually , the  Redmi Note 3 is not in the compatibility list , we are unable to guarantee its performance. Please visit:  http://www.dji.com/mavic/info#specs
Please re-install the APP, then try it again , if it is still the same , I would recommend you try other mobile devices.

Even if the device is in the compatibility list, YOU can't guarantee its performance.

DJI should do some more BETA-testing before releasing updates...
