I'm getting a low-quality video and lags when flying a few meters away. I tried to replace antennas from a working build but it didn't help. I tried to write the latest firmware again, no luck.
It seems that after I change to high quality and then change back to low latency is fixing the issue and the bitrate is up from 8Mbps to ~25Mbps
But After I power off the same issue persists.
I checked and the unit gets proper 12v when it's operated.
No SD card in the unit.
Any advice?
