You might have dabbled with this type of Android if you have used custom ROMs. Many third-party developers have taken AOSP and built it as-is for popular phones and tablets. It's pretty bare-bones, but does have everything you need to power and use a smartphone. Or possibly a robot.
The popular Android
There's a very good chance the Android you have in front of you isn't just powered by the open Android — it needs some extra bits included to make a very different version of Android. Don't feel confused just yet.
Whether you have a Nexus phone or a Samsung phone or a Motorola phone or any other brand of phone running Android, they all use a version of Android that has those extra bits. These extras aren't part of the open Android, and you can't freely distribute any of them (even it happens all the time, and generally nobody seems to be too bothered about it).
Your Samsung Phones or Galaxy J or A Series runs Android. So does your HTC M9. Or your Sony Xperia. Even your Nexus 5. But they are all very different from each other, and are also different from the open version of Android — which they are ultimately based on.
But they are still Android. We want the extras, whether they be the Google applications and Google Play, or the features that Samsung has added. This is the Android we all use and love.
Gadgets are small tools powered by electronic circuits or a small technological objects (such as a device or an appliance) that has a particular functions and purpose.
