Yes it had its issues. And I'm not saying Android is the most secure os, I think thats Blackberry. And yes it is a issue with android being open source. Google has been working to make it more secure. I personally, and several others I know used Android for years and never had a issue. Android even shows which stuff the app has permission to, if the app seems like it dosent need those, somethings up and you would know. In the latest release and probably expanding on in the next one, once you download a app, you can choose what it can access.
I personally find the alumnium harder to hold and less comfortable, but I agree that Samsung is worse.
I think the point was that per marketshare %, Android is by far, like in a huge way, prone to malware.
For the most part, if you are a smart user, you shouldn't have too many issues, but when apps are in the play store, approved and officially "safe" yet not actually safe, even going so far as the not report what they are doing, even a wise user is going to run into an issue. worse yet, many don't even know they have an issue.
Going by number of malware attacks per marketshare %, iOS is by far the most secure. even more so than blackberry, whose marketshare is deathly low and yet nearly matches iOS in percentage of attacks. that's crazy. especially when iOS has so much marketshare.
blackberry used to be the rage, but they just haven't been able to move fast enough.
Schmidt hinted at Androids open source (in truth it's not actually open source) nature meaning its been tested more, thus making it more secure in that IT Expo interview (the one with folks in the audience who deal the security of these things and know better by experience laughing at him). So, it would seem being open source is supposed to be a benefit to security, like Linux enjoys. Not vice versa. Android has issues stemming from the way its put together and the inability to fully invest in some of its code due to possible legal issues from ip theft with Sun Microsystems. But thats another story.
