How to change the default Google account on your Android phone
Whether your use an Android tablet, Android phone, or both, you can switch between various Google accounts on your devices. However, changing the default Google account on them isn’t as intuitive as you’d think. The Google account you used during the Android device setup is set as the default account on your phone. Over time, you might have added more Google accounts to your phone, and now you want to set a different Google ID as the default account and not be stuck with the one you used the first time.
