If you need to debug in a physical Android phone or just don't want to use an emulator and save a lot of your machine resources, it's possible to control an Android phone directly from your computer with Scrcpy.
With Scrcpy you can share your phone screen and interact with it using keyboard and mouse. Its biggest feature compared to other tools is the low latency, that make us feel like we're interacting directly on the phone.
Credits goes to May, that showed me the tool a few months ago.
Free and open source, available for Windows, Linux and MacOS.
