Newer phones produced by Samsung come with an already installed Device Maintenance application. You can use its vast array of functions for one of few areas: Battery, Storage, Memory, and Device Security.
We will focus on the Device Security function and how using it and Device Maintenance can help you make your phone much more secure. The app regularly scans your device for any possibly malicious software and provides you with solutions on how to deal with them, all backed up by Intel Security.
That's it! Remember to scan your phone at least once a week and avoid opening software from unknown sources!
