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.

Additional context and comments

Expected Behavior

Phone Authentication should work as it does on Android 13, without throwing the missing client identifier error.

Details:

• Device: Redmi 13c
• Android Version: 14
• Firebase Authentication SDK: Latest (using Firebase Phone Auth)
• Flutter Version: 3.24.2 (Stable)

Key Configurations:

• APK signing: Using a release keystore.
• App Integrity: App Check with Google Play Integrity API enabled.
• SHA Configuration: Both SHA-1 and SHA-256 keys are added in Firebase Project Settings and App Check.

Hello @omar-hadek, I see that your device is a Redmi 13c. It may not come with Google Play Services installed by default which will impact the ability for the Phone Authentication to check for genuine request. Unfortunately, there is nothing that FlutterFire can do to mitigate that. If you feel like it's something that should be solved, you can open an issue at https://github.com/firebase/firebase-android-sdk
