I have a new Phantom 4 Pro v2 that I received Wednesday. The first time I tried to fly it was difficult, as the DJI Go 4 app kept telling me that the battery was not detected. It took me a little searching to find that there is a switch inside the battery bay that detects the battery. Pressing on the battery I was able to get that error to clear and get the bird in the air.
Since then I have tried and tried, and no matter how I put the battery in, it always starts out with that error, and I always have to go back and press on it some more while watching for the error to go away. Only then, can I take off. When I land, I would guess that about 50% of the time I get the same error again, just from flying vibrations. Thankfully, once started, it doesn't stop the motors if it works its way "loose" from the switch. The battery is always secure, with both latches securely clipped, it just doesn't hit that switch.
I have the DJI battery that came with the bird, and two after-market batteries. All three batteries have the same issue, so it's not a battery issue but an issue with the bird.
Am I going to need to send this off to DJI and wait for months to get a replacement? Should I return to Amazon as defective (there was a note in the packing that said any return was subject to a 20% fee). Is there any way that this is fixable by me (a person who is quite adept at fixing all things, including electronics), or am I going to end up voiding my warranty? Is this a common problem?
Also, I have DJI Care Refresh. If I replace through Amazon, can my refresh be transferred?
