Android OS is an open source operating system developed by Google. And, as an open source OS, of course, all parties should develop an operating system with no fear of a patent.


One example of a company that has been modified Android OS is then pinned to the Amazon Kindle Fire. They have modified Android OS as far as possible so that virtually Kindle Fire has no resemblance to Android. In addition, its use is way different from Android.

Furthermore, there are several mobile phone manufacturers from China who do the same. They take the Android OS source code plus a few apps on it and then embed it on a phone or tablet product. And, it still
does not matter to Google.

However, the tablet or the smartphone will not be any such thing as Google applications. From the built-in Gmail, Google Search, Google Maps, Google Chrome or Google Play. None of the Google apps is an open source application. To obtain the application officially, a company must membangn partnership with Google. Specifically, the company must be part of the Open Handset Alliance (OHA).

By becoming a member of the OHA, a company can freely embed various Google applications in a cell phone. However, instead the company will not be able to act independently to modify the Android device. In addition, the company also can not delete the Google applications from their devices.

And this is what they do on the Acer. On the one hand, Acer is part of the OHA. And, as a member of the OHA, Acer is not allowed to release smartphones that are incompatible versions of Android.
