It is a firmware issue. Don’t have this issue on my V3s. I have sent a message to @WyzeBaohua this morning to see what is going on.
From what he will tell me, I could to go back to the firmware level to demonstrate from which version this problem appeared. For the moment, I don’t feel like wasting my time for nothing. I’m waiting for his answer.
Should you update? Apart from this small problem, everything works fine. Most users will not notice this issue. Those who will notice it will be playing with the zoom and in low light conditions. Then they will look at the drop in bitrates and they will see a correlation.
These 2 firmwares are installed in 8V2s and 3 Pans. No other problems.
