How to change publisher name in Google Play
Solution 1:
In the Developer Console, go to Settings, and change the 'Developer Name'.
Note that this name is the same for all of your apps. If you want to keep your name for other apps, you need a separate developer account and file for an app transfer.
Solution 2:
Sign In to Developer Console Click the Gear Icon on the Left hand Panel Under Settings > Developer Name > Change it to your Desired Name. Ctrl + F5 > to see the changes..
Solution 3:
Google often changes its design. So for now we need to go to Google Play Console main page, then select in the left pane "Developer Page". There, we can change the developer name.
