I don’t know how widely known this story is, but there was a highly rated app called Virus Shield in Google Play that had around 10,000 installs. People liked it, it didn’t slow down their Android phones and tablets like some other apps, and it had a very simple interface. Turns out, it didn’t slow down their devices because all it did was display a couple of images. It didn’t do anything to protect the devices whatsoever. What it did do was get 10,000 people to pay $3.99 for it. How can apps like this be avoided?
