so when you go into settings-device care-security you don't have the option to scan your phone?
Can you take a screenshot of what is in your Device care-Security page?
@userQfZsy31Y0N tap on the three buttons in the top right of that screen and open the Advanced section. Any options from there?
This might be an option only on some country models. In the US I have this.
What country or version of the phone are you using? Is it a locked phone?
Some carriers don't include this option, like Verizon: https://us.community.samsung.com/t5/Galaxy-S-Phones/Device-Care-Security-Icon-Missing/m-p/1191860/hi...
