10 Essential Tips on How to Protect Data in an Android Phone

1. Use a Strong Screen Lock

Avoid simple patterns or 4-digit PINs. You can set a complex alphanumeric password for better security. Biometric options like fingerprint or facial recognition are also available on phones such as the Samsung Galaxy A54 (₹35,499) and OnePlus Nord CE4 (₹24,999).

2. Keep Your Phone’s Software Updated

Manufacturers like Samsung, OnePlus, and Realme regularly release security patches. Always update your device to the latest Android version. Go to Settings > System > Software Update to check.

3. Download Apps Only from the Google Play Store

Avoid downloading APKs from unknown websites. Google Play Store apps are scanned by Play Protect, reducing malware risks significantly.

4. Review App Permissions

Apps often ask for unnecessary permissions. Go to Settings > Apps > Permissions and disable access to contacts, camera, and microphone for apps that don’t need them.

5. Use Google Play Protect

This built-in tool from Google scans apps on your device for malicious behaviour. Go to Settings > Security > Google Play Protect and enable it.

6. Enable Two-Factor Authentication (2FA)

Activate 2FA for your Google account and any other critical apps (like Paytm or PhonePe). It sends a one-time code to your phone, adding a layer of protection.

7. Avoid Public Wi-Fi or Use a VPN

Public Wi-Fi networks in cafes or airports are breeding grounds for hackers. If necessary, use a trusted VPN service. For example, NordVPN and ProtonVPN offer Android-friendly apps with Indian servers starting from ₹300/month.

8. Encrypt Your Phone’s Data

Most new Android phones come with automatic encryption, but it’s worth double-checking. Go to Settings > Security > Encryption and enable it if it’s off.

9. Use Trusted Antivirus Apps

Apps like Bitdefender Mobile Security (₹399/year) or Kaspersky Mobile Antivirus (Free & Premium) provide real-time protection from malware and phishing attempts.

10. Back Up Your Data Regularly

Use Google Drive, Dropbox, or even a secure USB to back up your phone data weekly. In case of a breach or device loss, you won’t lose everything.
