App users generally only see and only care about the end result. Let's take the Google Play Store as an example. The Play Store needs to look nice and be simple enough for users to download new apps and keep their current apps working and up-to-date. The service that makes this possible is called Google Play Services and, without it, Play Store just wouldn't work properly.
Google Play Services is an app that runs in the background and you can't explicitly open it. However, its use is crucial for all Google apps on your phone and the apps you've downloaded from Google Play. Also, app developers can use Google Play Services for their app to take advantage of useful Google features like Google+ integration, using Google Maps, and distributing app updates easily through the Play Store.
This app acts as the middle man between the apps you install and your Android operating system. Many apps you download rely heavily on certain Google features such as Maps or your Google account. Without Google Play Services, this connection could not be established and many apps would not work properly.
In conclusion, its functions include managing app installations and updates, integrating Google services with various apps or devices, account authentication, and contact synchronization. It's vital for all smartphones powered by Google and you must always install the latest version on your phone as many problems can arise if you don't.
