Android google map shows white screen on production

Question

I have a small app which shows a location on google map. It shows location on the map when I deploy from android studio to real device without any issue. But when I deploy the code to Google store, and install from there it shows white screen with colored "google" word in the left bottom corner. I created new google map API code and deployed, still getting white screen. What could be reason? The issue is observed in Oreo and pre-Oreo android versions, and multiple types of Samsung Galaxy phones.

This is happening because your got the API key with a debug build certificate but at the time of releasing you either need to create a new API key for your release build or update the current. To know how to find release fingerprints see this.
