Hello, I would try to reset the setting to the factory default. Maybe this would help to reset the GPS module and recalibrate it.
How is this done?
 

I bought a Hubsan Zino 2 (1 year old). I replaced the battery on the radio - I inserted a stronger one. I don’t know if this is the cause, but when I want to do a GPS Accuracy test, it shows me that my phone is 35m away from the drone. After that, I can't use the "orbit" function. I do everything as instructed.
Can anyone help me
