Samsung is the biggest manufacturer of Android devices, at least outside of Asia, and they are a fascinating company with those devices. Samsung uses Android, and the Google ecosystem, but has still managed to create its own software and services ecosystem. The company has tried ot be unique, and offers alternatives to Google’s apps and services while still offering those services on its phones. The success of this is mixed at best, but at the end of the day, the most Android devices in the western market are Samsung devices.
