It also, very annoyingly, can't connect to multiple networks at once. e.g. connecting to a wifi network which doesn't have internet access (and doesn't even advertise a default route) and a cell phone network at the same time. Linux can do it, Windows can do it, Android stubbornly refuses (and indeed many variants will refuse to stay connected to a wifi network without internet, if not just make you jump through confusing hoops). There are some APIs which mean that if you write an app, you can do it just in the app, but there's no way as a user to get it to do so.

Same with iOS. When I connect to my dashcam to download some videos I get a pop-up after a while that is like: "No internet detected, switch to cellular?" I tap remain connected. No option to disable that. And even though I wanted to stay connected, iOS decides it knows better and reconnects to my Carplay network.

  As far as I remember this have a solution for both Android and iPhone. Probably your dashcam just doesn't implemented them right. https://developer.apple.com/forums/thread/13164 https://developer.apple.com/forums/thread/13164

    Only if you have an app. It could well be the only reason you would want to make a custom app, because of this irritating behaviour by the OS.

  This actually works fine on iOS when the app is implemented properly. I have multiple devices where I do this without issue. I’m guessing your dash cam app is not implemented correctly.

    The phone is the network manager, though. It relying on a specific optional part of the spec to be implemented on a different device seems to be a huge flaw.

    The point is it shouldn't need a damn app, much less one to implement it "correctly".

This is incredibly annoying. If my internet goes down I'm unable to diagnose it from my phone because it won't stay connected to the WiFi that doesn't have internet. DNS is also messed up on Android, it refuses to use the Dhcp supplied dns without having to set multiple options and even then some internal dns refuses to resolve.

It's even more annoying when you go to mainland China with your western Android phone. They determine internet connection by trying to connect to Google services. If you connect to a local WiFi, of course it won't go through the Great Firewall, and every single time will prompt you asking if you want to keep the internet-less connection.

Windows also cant do it, right ?, If i have 2 Wireless adapter on Windows, i can not connect to 2 seperate Wifi networks(at least with using the GUI, did not try using terminal)

  Yeah, you can! If both if them advertise a default route via DHCP, it can get confused (it's basically random which one it will try to connect to the internet with), but it will otherwise work. It also needs the local IP ranges to not overlap. And if the wifi network without internet doesn't advertise a default route, it'll work just fine by default.
