How do I test my game on my android phone?

I tryed the QR code Remote Preview but for some reason it stuck a 33kb loading. No idea why or what to do.

But anyway I was wandering how to install the game on my phone without going through the PlayStore.

Thanks

Export the game as debug APK. Then transfer this APK file somehow to your phone. You can connect the phone to your computer with USB cable, or send the file by email etc.

Then locate this APK on your phone and tap it to install.

You may need to allow "installing apps from unknown sources" in your phone settings.

Thanks a lot.
