In this article, we will discuss everything you need to know about recognizing, removing, and preventing virus infections on your Samsung S20.
Understanding Smartphone Viruses
Before diving into removal strategies, it is crucial to understand what a smartphone virus is and how it can affect your Samsung S20. Unlike traditional computer viruses, mobile viruses are designed specifically for smartphones and can perform a variety of malicious activities, including stealing sensitive data, sending unsolicited texts, and draining battery life.
Common Signs of a Virus on Your Samsung S20
Identifying a virus is the first step in addressing the problem. Look out for the following symptoms:

- Touch and hold the “Power Off” option until you see the “Safe Mode” prompt.
- Tap “Safe Mode” to restart your phone.
While in Safe Mode, check for unusual behavior. If your device behaves normally, a third-party app is likely the culprit.
2. Remove Unneeded Applications
If you’ve identified an app as the possible source of the virus, it needs to be removed. Here’s how to do it:
Steps to Uninstall an Application
- Open the Settings app and select “Apps.”
- Find the suspected app in the list.
- Tap on it, and choose “Uninstall.”
It’s crucial to keep an eye on the permissions requested by applications. If an app requests more permissions than necessary, consider removing it.
