A working preview of call-in login with Auto-Verify — download it, install it, and test the flow on your own phone.
Open this page on your Android phone — send yourself the link, or open it from wherever you shared it. This only works on Android — not iPhone.
This opens an install page with an "Install" button — tap it to start the download. You may see a browser warning about the file type — tap Download anyway or Keep.
When you open the downloaded file, Android will likely block it the first time with "Install blocked" or "For your security." Tap Settings, then turn on "Allow from this source" for your browser or Files app, and go back.
You may see a Google Play Protect warning since this isn't a Play Store app — tap Install anyway. This is expected for a test build.
Enter a number, tap "Call Now" when prompted (it opens your real dialer), and watch Auto-Verify capture the code and log you in automatically.
This is a test build, not published on Google Play — that's why Android shows security warnings during install. That's expected and normal for internal testing, not a sign anything is wrong.
It's an Android-only preview (.apk files don't install on iPhone). The call-capture step is simulated for this preview — it demonstrates the intended user experience rather than live call-audio detection.
