Your Google account and therefore all connected apps (such as Google Play) are linked to a unique email address.
If you want to become a beta tester, I need your email address from your Google Play account.

Step 1: Open Google Play

First, open the Google Play app on your Android smartphone. You can easily search for it in the menu. In most cases, the Play app is already on your home screen.

Step 2: Check your account

In the Play app, in the upper right corner, there is a colored circle with a letter in it or your selected user logo.
Click on it to find out your email to your Google account.

Step 3: Your email address is ready

Now you will see your username and email address. Please let me know if you would like to sign up for the beta test.
