Good day, in support addressed, the answer is one - send for repair. Intsedentov with the copter was not, there were just 10 flights. I'm not the only one with this problem. https://forum.dji.com/forum.php?mod=viewthread&tid=176038&extra=page%3D1%26filter%3Dtypeid%26typeid%3D640%26typeid%3D640
please tell me what can be done? Can I send You a log?

Thanks for the prompt reply. We understand that you're encountering the situation, however, this problem might be related to the internal parts of the aircraft and it can't be fixed via remotely. What we could recommend is to send the unit for further evaluation. We do appreciate your understanding and cooperation.
