So what's the deal with all the malware, viruses, etc. on the Android OS? I was thinking about switching to a Galaxy 4 from my current iPhone. But I've been reading so much about threats to Android, like malware that can send texts without you knowing (which you have to pay for), plus logging your keystrokes, recording from your microphone...really scary stuff. Anybody have any insight on what's going on? Do you regular users have to worry about that stuff? And how do you protect yourself?
