I'm not convinced it's necessary. Both iOS and Android have sandboxing features that prevent malicious code from running. Android, of course, lets the user run it anyway if they give that app permission. I think iOS has something similar but they have a pretty decent app store that prevents that type of thing, unlike Google.
I am an Android guy by the way.
I'm not convinced it's necessary either, but I believe I was infected and now I'm all paranoid.
One security research firm (I don't remember the name I'll have to look) went through the Google App store and downloaded as much malicious stuff as possible. They found that unless the application is given permission, which means a user has to allow it, then it really can't do anything on the system. If the user allows it then, obviously, the malicious code was able to execute and do it's thing.
That's exactly what creeps me out about Android - why does everything need permissions to stuff you wouldn't expect it to use. I fear the answer is "to slurp your data". Which is garbage. However the app won't run without it.
Example: "Samsung Briefing" which is a news aggregator - asks for permission to save to disk, phone, etc etc
The newest version of Android took a cue from iOS and now lets you be more judicial with app permissions. Haven't been able to play with it yet.
in what way? I don't see a way to prevent, for example, Skype from using my camera but allowing it access to the network and microphone.
Do you have Nougat? I could have sworn that was one of the selling points. Where you give permissions like that on an as needed basis. So you could very well prevent skype from accessing the camera but allow it to access the microphone. It may not work as expected but...
The one on the phone. Worst feature of the phone. You search for a common app that you want and you get scores of results of malware, all with the exact name of the product and/or company that you were looking for.
I've never had that happen. and I've had a few different windows phones.
We had a few. But there is only one store. It was very much a "CloudatCost" level of service. Looked good till you actually search for an app then realized you had no assurance of which one was real. It made me appreciate the lock down of the iOS system that someone was vetting the vendors and at least attempting to ensure that products weren't trying to trick you.
Biggest ones were things like the Chrome browser. Search for it and it didn't exist, but hundreds of things called that did.
