Firebase Phone Auth not working in release build

The OTP verification works properly for debug build. I have also added SHA key in firebase console for release version. But Phone Auth doesn't work when I generate signed apk and upload it to play store. Should I retain both debug SHA keys and release keys after I upload the app to production on play store? Is Google App Signing compulsory for using a firebase app on production?

If this is the issue occurring on the app uploaded to play store, then below can be a feasible solution.

Steps

  1. Go to play console and select your app.
  2. Under release management, go to app signing.
  3. Find SHA-1 certificate and copy it.
  4. Go to firebase console and select your app.
  5. Go to project settings and add this SHA-1 certificate.

You are ready to rock again.

You need to add SHA-1 certificates. And if they are already added and you still face this problem (as in my case). Add SHA-256 as well and it works!!!

  3. Copy SHA-1 certificate and SHA-256 certificate.
