Additional ways to safeguard your device
Here are a few tips and suggestions for you to be in the safe zone.
- If you use public Wi-Fi (Wi-Fi networks in a shopping mall, club, or hotel, etc.), your phone is visible to everyone on that network. In this way, you are vulnerable to an attack. Hackers or attackers can attack your Android device through the Wi-Fi network.
- Do not connect your Android device to open Wi-Fi networks. Even if you connect to the Wi-Fi network of a trusted store, we recommend that you use a VPN (Virtual Private Network). A VPN creates many security coatings for your connection. In this way, you can stay safe from attackers.
- Only install apps from trusted sites and application stores. Never install suspicious apps or apps from unknown websites.
- Regularly update your apps by checking and installing them as soon as possible. Keeping your apps updated makes your phone free from risk.
- Know about any software or application before you install it. Read and know about the developers of the app, the number of users, and the Play Store rating for that app. Also, go through the user reviews of an app before installing the application.
- Install good security software on your Android phone. This can block malicious apps even if you install them unknowingly.
