2. Identify the Suspicious App: Review your installed apps and identify any unfamiliar or suspicious-looking applications. Pay attention to recently installed apps or those with unusual names.

3. Uninstall Suspicious Apps: In Safe Mode, go to "Settings" > "Apps" and locate the suspicious app. Tap on the app and select "Uninstall." Follow the prompts to remove it from your device.

4. Clear App Cache and Data: After uninstalling the suspicious app, go to "Settings" > "Apps," find the app again, and select "Storage." Clear the cache and data associated with the app to ensure no remnants remain.

5. Reboot Your Phone: Restart your Samsung phone to exit Safe Mode. This helps ensure that the phone is operating normally and allows you to verify that the suspicious app has been successfully removed.
