Install Google Play to AMIDuOS
AMIDuOS was shipped and gets installed with only the basic apps and an Amazon Appstore as default. I am pretty sure that you want to install the official Android AppStore from Google and you don’t have any idea how to do it.
Google Play Store is just another app in your Android device and installing the AppStore is really very easy. Take note that you need to install the correct Google Apps for your version of Android OS to avoid problems.
