There are many apps on Google's Play Store that can be dangerous to use, which is why you should scrutinize the permissions that each app requires before installing it. Some apps cross the line by installing malware on your smartphone that can compromise all of your personal data (including username and passwords you enter on your phone). A good example of this type of infiltration is through a simple flashlight app used by hundreds of millions of unsuspecting people. Brightest Flashlight Free and Super-Bright LED Flashlight are just two of the many flashlight apps available on Google's Play Store that require too many permissions and installs malware.

"When I was in college, the main campus library had several computers set up on the first floor for public use, and invariably, whenever I used one, a previous user had not logged out of her Gmail account. So when I tried to load my account, I would instead find myself staring at the entire contents of someone else’s inbox.
