Answer 1

On the phone

1. Have you enabled Developer Mode?

2. Have you enabled USB debugging within the Developer Tools menu in settings (this menu doesn't appear unless you've enabled Developer Mode)

3. Do you have a good and securely connected USB cable?

In Android Studio

1. In Edit Run/Debug Configurations, do you have "Target: USB Device"?

2. It may help to download the latest version of the USB driver for that particular phone.

It's also helpful to know whether your phone appears as a recognised device at the operating system level. And when in doubt, reboot everything you can think of.
