Problems using my S5 as a video camera on the bike

[GoldOxide_imp]

I am wondering if the phone was - by fluke - sensitive to spark ignition interference? This the first time using the phone while riding the CB? Maybe I misunderstood, but did the problem persist after you walked away from the CB?

Good thought, although popgun's concern about the serial data bus may be more likely since standard spark plugs are resistor (LMAR8A-9S 6817).

However, any arcing from a loose spark plug cap could be an issue. Does not explain why it only affects video.

I agree with a possible loose spark connection or questionable lead wire under the tank. However, I can't see any serial data bus creating interference with video. High-speed serial links are supposed to be shielded, but even still, the shielding is there to protect the serial link data, not the other way around.

In regards to the video driver and/or screen module: It could be possible that over time an "antenna" has formed (e.g. something come loose, something lightly shorting inside) in the phone circuitry related to the video that is picking up on interference and corrupting scan data. Of course, you will need to determine if it is being recorded that way, in which case it is not a video problem but a camera or write storage problem (e.g. micro SD card connector does not like the CB subtle vibration?). Is the playback okay on another device and/or away from the bike?
