What is the Android system WebView app and how can I use it?
Android’s Webview, as described by Google, is a “system component powered by Chrome that allows Android apps to display web content.” In other words, Webview allows 3rd party apps to show content in an in-app browser or in an app screen that pulls from the web. It’s pretty important, and has only recently (with Lollipop) been decoupled as a stand-alone system component that can be updated as Google sees fit. And that’s important, because it allows Google to push security fixes and other enhancements without the need to push an entire system update.Source: Droid LifeUpdating answer after Quora merged the question with "how can I use it?" part.Update: You don't have to do anything explicitly to use it. WebView enhances your experience while using app which makes use of it. Just keep the WebView updated to have smooth and problem free experience.
How do I manually upgrade my Android 4.4.2 to 5.1 Lolipop?
It isn't as easy as that. Upgrading your Android version is only possible when a newer version has been made for your phone. There are two way to check:Go to settings > Scroll right down to 'About Phone' > Click the first option saying 'Check for system updates.' If there is an update it'll show there and you can continue from that. If nothing shows up there isn't an official update for your phone to the next Android OS update. If your phone doesn't have an official update, you can side load it. Meaning you can root your phone, install a custom recovery and then flash a new ROM which will give you your preferred Android version. Now, this process is just as complicated as it sounded and also voids your phone's warranty. If you still want to go ahead with this, you can Google for the methods to root your phone and later, how to flash a custom ROM.Hope this answered your question.
