APK installation failed

Hi,
I am new to game development. I built an android game and I want to test it on my phone. There was no problem with the file packaging but I cannot install the apk file on my phone(I directly transferred the apk file on my phone ).


these are the settings that I use.

what is your android version on the phone?

Don’t update, do a clean install . Make sure that you have enough storage space. Enable the installation from Unknown Sources. Make sure that the APK file isn’t corrupted or incomplete.

Just open your browser, find the APK file you want to download, and tap it – you should then be able to see it downloading on the top bar of your device. Once it’s downloaded, open Downloads, tap on the APK file and tap Yes when prompted. The app will begin installing on your device.
Thanks

Go to developer settings and disable verify apps via USB . Then you can install .apk without any problem.

Make sure your android version supports sdk version (android 10 -api level 29)
