Description

I'm encountering an issue with Firebase Phone Authentication. On a Redmi 13c running Android 14, I receive a "Missing client identifier" error during the authentication flow. The same code works perfectly on Android 13.

Reproducing the issue

Steps to reproduce the behavior:

Set up Firebase Phone Authentication with Flutter.
Sign the APK with a release keystore.
Test on Redmi 13c (Android 14) – Firebase Phone Auth fails with a missing client identifier error.
Test on Android 13 – Phone Auth works as expected.
