Google and Android
In addition, Google also needs manufacturers to activate the " OK Google " command on their devices so that voice search works better on supported devices. Manufacturers also have to build Android brands that show prominently on phones or tablets - something that has been confirmed in the past.
Manufacturers can still say no to Google, and they can still do Android devices, but they won't have Google Play, or other Google services, that's what Amazon does and Nokia does.
Google is increasingly dominating Android
Because Android is so successful, it seems that Google is increasingly showing its ultimate power in this operating system and forcing every manufacturer to follow.
