As an Android user, a firewall is not even on my radar, nor do I hear much call for such things from the tech community. Not yet, at least.

My security measures, such as they are, are thus:

1. I use apps from trusted or at least reputable sources.
2. I don't leave network connection services open longer than necessary.
3. I use STRIP to securely store passwords and other sensitive data.
4. I use Android Lost to help manage the consequences of loss or theft. It can locate, and if needed, remotely wipe the phone.

I give my phone the same sort of physical security I give my wallet.

Since I don't see my phone as a particularly vulnerable attack surface, I don't even use a lock screen, much less more extreme technological security measures.
I'm more interested in making it convenient for myself than inconvenient for thieves.
