Overview of Android
Android works on many devices, including smartphones, tablets, wearable devices, Android TV, and even cars. Each manufacturer can offer a custom Android version as well, which makes it attractive for them since they can differentiate from one another.
The Android OS we see in our phones is not typically the “stock” (or “pure”) Android OS from Google. Every phone manufacturer can manipulate the original code to create a custom version with both visual and functional changes. However, Google has also partnered with renowned brands like, HTC, Samsung, LG and Motorola, etc. to launch phones with stock Android, known as “Google Nexus”.
Android is known as the most customizable mobile OS even without rooting. Android is designed for touchscreens, so all Android phones are fully or partially touch-based. Using widgets and quick app access icons, it provides all the information right on your phone’s home screen. Furthermore, it also offers great multitasking capability with the ability to navigate between multiple apps at the same time.
Android OS is constantly being developed and new features are added frequently. Apart from basic version updates, Android also gets major update releases that are normally code-named as dessert names, like Cupcake, Donut and KitKat, etc.
