I’m using an app to use my Android phone as a webcam, which works great (good low light performance!) provided I can stand it up somewhere above my laptop screen (finicky). You can accidentally knock it over. Might be worth considering if you don’t use the camera much - otherwise an external one will probably attach better and he more stable

Regarding your mouse double clicking, some Reddit users suggest pressing the click button quite hard a few times…

I believe they’re available as backup but re-calibrate themselves with GPS coordinates if available. This is not a problem when GPS jamming is used but becomes an issue with spoofing - the pilots need to monitor for it.
