Just sharing a recent experience: stock P3S, 1.8.10 firmware, DJI GO 3.1.3 on Android (Samsung Tab A 2016 7"). Did a flight last night down in a nearby canyon, passing right below some massive power lines that run across it. Went quite far (3500ft, personal record) so the P3S was just a small dot against a green background, but from the video feed, it was clearly turning right (yaw) on its own. I kept it straight with some left-stick input, but it was definitely weird. I believe it was caused by the power lines, as I've never seen that behavior before. Well, during the whole flight, I don't think I've received a single warning about interferences (got a couple about poor signal, but that's totally expected).
I've seen that interference message before, occasionally, for example when powering up the AC & RC inside the house, but rarely when flying (it's not a scientific analysis, but if I don't remember it being an annoyance I guess it didn't pop up more than a couple times).
So either Daz's theory about this being an iOS issue is correct (it could very well be, maybe the AC just sends back an "interference level" and the actual warning thresholds are in the app, so DJI GO / Litchi / Android / iOS could behave differently), or some units are more sensitive than others.
