Drawer with ScrollView and basic HTML mobile site.

I added a ScrollView inside the LinearLayout of the drawer and added an option to show a basic mobile site, designed for feature phones, which has no JavaScript. I remembered this from my J2ME LG800G feature phone that I had two phones ago. I made this for people like me with a carrier that does not support Facebook Zero, but have a strict data plan. I did this by setting the user agent to an old version of Firefox for Android. 

What do you think?

Here is a screenshot of the site: (private info removed, and from my laptop, not the app for convenience)
