How to protect your Galaxy device from malware

Last Update date : Dec 28. 2021

Since Galaxy devices scan for malware before downloading apps from the Play Store, the chances of your device being infected with malware are low. However, harmful software can still be installed on your device through ads or e-mails. Follow the guide below to further protect your device.

Before you try the recommendations below, be sure to check if your device's software and related apps are updated to the latest version. To update your mobile device's software, follow these steps:

Step 1. Go to Settings > Software update.

Step 2. Tap on Download and install.

Step 3. Follow the on-screen instructions.

Decide which apps to allow access to

After installing an app, you can decide which apps to allow access to your device. A malicious app may leak information from your device, so be careful about granting permissions. Even if you allow access, if you haven’t used an app for a while, its permissions will be automatically reset and you will have to grant permissions again when you use the app next time.

How to change app permissions:

Even if you visit safe websites on your device, you may still be exposed to harmful ads. Due to the risk of malware infection through harmful advertisements, we recommend using the ad blocking function in the Samsung Internet app to limit pop-ups and protect your device.
