Fix a Problem
Why does Android sometimes fail to autofill SMS verification codes?
SMS verification-code autofill may fail if messages are delayed, app permissions are restricted, the keyboard/autofill service is disabled, or the site does not support the Android autofill mechanism.
What to do
- Verify the actual SMS arrived and the SIM has service.
- Check default SMS app, autofill settings, and keyboard permissions.
- Manually enter the code if suggestion does not appear.
Limits and compatibility notes
Check this before relying on the answer
Never share one-time codes. Autofill is app- and website-dependent; receiving an SMS does not guarantee a suggestion.
