An ongoing Android malware campaign called Triout is recording calls, collecting photos, and reporting your location.
In 2016, an app called “Sex Game” was available in the Google Play store. And while it was legitimate, the bluntly titled app did not last long in the store. Soon it was gone.
Now, two years later, it’s back...but not really. It is not available in the Google Play store, though it shows off a Google Debug Certificate. You’ll only find it in shady third-party markets, and it is loaded with a spyware called Triout.

Stick to official app stores — While it may be tempting to search for a better deal in other venues, this is a time to go only with apps of which you are 100% sure. There are too many fake app scams to risk it. Avoid pirated copies of anything as well, as those notoriously come with malware stowaways.
