How to Install the Google Play Store onto the Mediatek X20
I’m afraid that we can’t advise you how to install Play Store on the X20; this is part of Google’s propriety code for Android and there isn’t a legally licensed version available for X20.
You could look at side loading, either to install the software you want directly or to install an alternative repository such as f-Droid or Amazon Appstore .
Thank you for that information and suggestion.
