Smartphones that run on a custom version of Android usually come bundled with third-party apps. For example, Samsung and many Chinese smartphones have bloat apps built-in. Many of these apps are useless for most users, and some of them collect users’ data and send anonymously to remote servers.

Recently, a Redditor spotted a spyware app pre-installed on all Samsung Galaxy phones. The user found that the Storage scanner/cleaner app in the Device Care section of Galaxy phones communicates with Chinese severs. The app is by a suspicious Chinese data-mining/antivirus company named Qihoo 360.
