!rant && dev

Before I dig deep and pick the minds on S/O, I'm trying to test an app (Cordova) on my wife's phone (Samsung/Android 7) - the feature I'm testing works fine on mine (Huawei/Android 8).

Where it seems to be faulty is making a WebSocket connection to my server - is there any known issues people are aware of? Recent security updates or something?

I'd jump straight on to USB debugging, but last time I tried to do this on Samsung, it simply failed to show up as a known device - tried loads of drivers...
