If you are using Android or if you use any other mobile phone, you must have heard of the Google Play services for instant apps. It is a popular feature and many people have benefited from it. Many people get an instant access to applications through Google Play. The way how this got to be is by noticing that certain function of certain apps has been changed/broken/disabled.
This is because Google has made a way for all applications to be downloaded directly from their site. When I downloaded one of my favorite games, "System Info for Android", the application starts by downloading the entire game from Google Play. So I installed it and after that it displayed that indeed this particular application had been installed just yesterday. This means that Google has updated their system through their application and made this a "New Feature". The reason why the applications are getting "New Features" is to make sure that they do not have anything that will break their application.
This means that users would get their free applications immediately after downloading them. This means that they are protected from any viruses, malware, and spyware. This is because Google is always keeping a watchful eye over their systems to keep them safe from unwanted things. This way they can make sure that their users are always on the safe side. So if you want to get your free applications instantly, try to install the Google Play services for instant apps from your Android phone. You will never look back at this decision.
