In the Google Play app store, an application for the Monero mining with a "defect" was found. Monero Miner successfully coped with the stated task and really mined the crypto currency, using for this purpose the computing power of the Android devices, but their owners did not become richer from it. This is reported ESET antivirus company.
The thing is that mined XMR coins were send to the scammers addresses, not user's.
The general mining fever helps scammers. Some of them hide the function of mining in their mobile applications for hidden mining using the users' devices. Others, on the contrary, specifically develop applications to deceive novice miners.

To date, the application has been removed from Google Play. Before that, up to 50,000 users could install it.
