I just got my P3S a few weeks ago and love it. I have logged 20+ flights with no problem. My Friend just ordered one last week and received it today. He got it out and went by the instructions included. It wouldn't connect the Wi-Fi at all. We tried all the troubleshoot guides I could find available online and in the Manual. He did contact DJI and tried all diagnostics with no avail. I was just curious how common this is ? This was a brand new quad by the why. DJI has requested he send the unit in for repair or send back to vendor he purchased from. I have been looking at this forum for a while. I haven't notice any DOA's.
