I have a question.  If you are using custom on channel settings, do you use one that has no red or green bar?  I have a few channels that are clear and have no red or green bars.  Or do you want one with at least a green bar showing?  

I tried a channel that has no bars at all and it seemed to give me the best range without video drop outs.

Thanks all

A channel that has no bars means it is unoccupied, therefore it is the best choice. However, selecting a custom channel means the system cannot cope with interference if someone else starts using the channel you select. You are far better off leaving it on automatic, so the system can choose its own channel if others are occupied.

Unfortunately, the P4 does not change channels anyway, (very seldom and when it does, it is not when the signal is low). I have been doing range/signal testing last few days and in about 60 minutes of flight time, it switched channels 3 times.  But it did not switch channels when the HD signal was going to get lost. My  hope was that once th esignal is almost 0, then it should switch to another channel.

But I keep it in Auto anyway.

My long term plan is to keep records of which channel(s) work best in the different areas I fly.  I will then go Custom.

BTW: You will have to use Litchi if you want to see which channel the P4 is using during a flight. The Go app does not include the channel.  Maybe DJI will add it soon, so we can all see it.

None of them change channel based on signal strength, it is only based on interference from another signal source.

I don't think so, the channel change is done in an instant, there should be no interruption.
