Android is one of the best mobile operating systems. You can find it in smartphones, tablets, smart watches, fitness trackers, and even in your car dashboard soon.
The success of Android is partially due to its flexibility and open source.
This means Android device manufactures can easily customize Android to add some unique features. For example, Samsung uses the TouchWiz skin to add tons of exclusive (sometimes, gimmicky) features to Galaxy devices.
But there are still a lot of common functions and features shared by most Android devices. And a lot of Android device owners are fiddling around the gadget to find out how to access some existing features.
So, this Android 101 page was created to help you.
These how-to guides will cover some basic features that you can easily follow on your device (mainly phones and tablets). Of course, some advanced features that may involve using ADB or rooting the phone will be covered as well. These Android guides should work on most Android versions, including Gingerbread (Android 2.3), Ice cream sandwich (ICS, Android 4.0), Jelly Bean (Android 4.1, 4.2 and 4.3), KitKat (Android 4.4), Lollipop (Android 5.0 and 5.1), Lollipop (Android 6.0) and Nougat (Android 7,0 and 7.1).
