When I’m writing code for .NET MAUI in Visual Studio, I often use actual devices. I’m working on a app that uses BLE and you really can’t test that with an emulator. And I usually test with a wired ADB connection. If you in the middle of working in VS and you unplug your Android device, VS will change the current debugging target from your device to the last used emulator. When you plug your device back in, it does not switch back to your device.
