I use Malwarebytes which has a good privacy manager that tells you what apps do and their permissions.
There ar many other similar apps in the store.
Is there a app I can download that will better describe all my applications and programs in my application settings? I want to know exactly what all my applications on my Galaxy S2 do. I'm suspicious that some are used to spy on my phone and hack into it, and use third party remote access (if that's the right wording) by my ex partner. My phone doesn't explain there uses very much at all, some I can't even see the entire name of the program because it doesn't fit on the screen.
