What an app permission can really do on your phone.

[RazrBoy23]

I'm just curious with these apps asking to have to the ability to access our personal info. Can they really go through our files on our phone? I notice that with every update they want to add new permissions. How safe is the information stored on our phone?

An app with read storage and internet permissions could potentially upload any of your files to a remote location.

You really just have to trust the application developers, use Afwall to block internet access to applications you don't trust or simply find alternatives with less intrusive permissions.

You have to understand, we developers must use permissions to create applications. A wallpaper application needs internet to download wallpapers and change wallpaper permission to set the wallpaper.

If a wallpaper application request read contacts permission it must have the ability to set contact pictures, if it can't set contact pictures this is a dead giveaway the application is likely malicious.
