Change screen preferences
<p>I have a business requirement, and after lot of googling came to a point that android (as compared to iPhone) would be the platform to go for</p>

<p>I have a requirement wherein lets say an App 'X' that comes built-in with OS (firmware) needs to be replaced with some App 'Y'.</p>

<p>Of course, i understand that there would be something that i would need to change at firmware level (correct me), and of course i have no idea how to do that</p>

<p>So, is such a kind of thing even possible ?</p>

<p>Any links where i could look for more.</p>
