Re: And still...
So basically you use your smartphone like a flip phone with a bigger screen that plays chess? Hardly worth having a smartphone at that point...
A lot of the worst Android exploits in the last year or two were related to receiving MMS messages and browsing. If you do either (and you really can't control receipt of MMS messages unless maybe you can disable it) then you aren't as safe as you think you are, just safer than people running stock Android phones.
