Do you know what browser you are using in your smart phone?

You don't like your smart phone browser. Find it and change it (you can change it for only iPhone and perhaps Androids).

Open your browser and type-in the following:
http://www.whatbrowser.org and you will get your answer as I got on mine (Android) Windows Phone 8.1 (I have to double check if this is true).

You can of course change it. Unfortunately none of these can be chosen as they appear to be not available for Windows Phone from windows store.

Here is the correct and complete answer: Go to WhatIsMyBrowser.com on Windows Phone.
