How to Check for and Remove Malware on Samsung Galaxy
While Android malware is less common than on desktop, it exists — especially through sideloaded apps or sketchy websites. Here's how to detect and remove malware from your Samsung Galaxy.
Warning Signs of Malware
- Battery draining extremely fast (background mining/spying)
- Unexplained data usage spikes
- Unfamiliar apps appearing without you installing them
- Phone running very hot even when idle
- Pop-up ads appearing outside of any browser
Step 1: Run Samsung's Built-in Scan
Go to Settings → Battery and Device Care → Device Protection → Scan Phone. Samsung's McAfee-powered scanner checks all installed apps.
Step 2: Boot into Safe Mode
In Safe Mode, all third-party apps are disabled. If symptoms disappear in Safe Mode, a third-party app is causing them. Uninstall recently installed apps one by one until the culprit is found.
Step 3: Review Recently Installed Apps
Go to Settings → Apps → Sort by Install Date — check for unfamiliar apps you didn't install.
Step 4: Revoke Suspicious Permissions
Go to Settings → Privacy → Permission Manager and revoke permissions from apps that have unusual access.
Step 5: Factory Reset as Last Resort
If malware is deeply embedded, a factory reset removes it completely. Back up your data first.
Best Prevention Practices
- Only install apps from Google Play or Galaxy Store
- Enable Auto Blocker to prevent sideloading
- Never click unknown links in SMS messages
- Keep One UI updated (security patches block known exploits)
