1. Location Access

What it is: Location services allow apps and websites to access your geographical position.

Risks: Constant location tracking exposes your movements to apps, advertisers, and potentially malicious actors, endangering your privacy and even physical safety.

What to do:

• Turn off global location services when not needed.
• For essential apps (e.g., maps, ride-sharing), set permissions to “Only while using the app.”
• Regularly clear your location history from device settings.

2. Contact Access for Unnecessary Apps

What it is: Many apps request access to your phone’s contact list.

Risks: Some apps use this to gather data on you and your contacts, which can lead to unsolicited messages, marketing calls, or data breaches.

What to do:

• Go through app permissions and deny contact access to apps that don’t absolutely need it (e.g., games, utilities).
• Be cautious even with legitimate-looking apps and social media platforms.

3. Advertisement Personalization

What it is: Your device and certain apps track user behavior to serve personalized ads.

Risks: This creates detailed user profiles that marketers, data brokers, or even hackers can exploit.

What to do:

• Disable “Ad Personalization” or “Ad Tracking” in your phone’s privacy settings.
• Opt out of interest-based ads in your Google, Apple, or respective device account settings.

4. Nearby Device Scanning (Bluetooth & NFC)

What it is: Features that continuously scan for nearby devices over Bluetooth or NFC, even when inactive.

Risks: Each scan broadcasts your presence, enabling tracking or even facilitating attacks like “bluejacking.”

What to do:

• Turn off Bluetooth and NFC when not in use.
• Disable “Nearby Device Scanning” features in Settings—this conserves battery and greatly reduces exposure to certain attacks.

5. Background Data Usage

What it is: Some apps continue to download/upload data even when not actively in use.

Risks: This drains your battery and allows apps to collect and transmit data without your knowledge.

What to do:

• Restrict background data for nonessential apps under “Network & Internet” or “Apps” in Settings.
• Only allow background data for apps that need to update regularly (e.g., messaging).

6. Microphone, Camera, and Sensor Access

What it is: Apps sometimes request ongoing access to your mic, camera, and other sensors.

Risks: This enables eavesdropping, spying, and unauthorized recording, posing extreme privacy risks.

What to do:

• Regularly review which apps have access to these sensors.
• Revoke permissions for any app that doesn’t require them to function.
• Turn off hardware access when not in use via “Privacy” or “App Permissions”.

7. Unnecessary or Useless Apps (Bloatware)

What it is: Pre-installed apps or rarely used apps sitting on your phone.

Risks: These can have vulnerabilities, collect data, or simply increase your attack surface.

What to do:

• Uninstall or disable apps you don’t use.
• Periodically review your app list and clean out unnecessary software.

8. Instant Apps

What it is: Instant Apps let you try out apps without installing them, but they might run with few restrictions.

Risks: Potential for easier distribution of malicious code and limited transparency on what data is accessed.

What to do:

• Turn off Instant Apps in your device’s Google or Play Store settings, unless absolutely needed.

9. Usage and Diagnostic Data Sharing

What it is: Devices share usage statistics, diagnostics, and crash reports with manufacturers and app developers.

Risks: While aimed at improving products, this option often sends more data than intended, and sometimes sensitive information.

What to do:

• Opt out of sharing usage and diagnostic information in “Privacy” or “About Phone” settings.

10. Lock Screen Notifications

What it is: Notifications for messages, emails, and other apps appear even when your phone is locked.

Risks: Sensitive information (confirmation codes, financial updates, personal messages) can be viewed by anyone who picks up your device.

What to do:

• Hide or restrict sensitive notifications on the lock screen.
• Customize which apps can display notifications when locked by going to “Settings > Notifications > Lock screen notifications”.

Additional Advanced Tips

• Review App Permissions Regularly: Many apps update and re-request permissions. Stay vigilant.
• Disable Wi-Fi Scanning: Wi-Fi scanning lets your device look for available networks even when Wi-Fi is “off,” exposing your presence and preferences.
• Restrict Device Administrators: Check for unknown or unnecessary device admin apps in “Settings > Security > Device admin apps” and disable them.
• Avoid Rooting or Jailbreaking: This undermines built-in security and makes the device more vulnerable.

Practical Steps

1. Open Settings > Privacy and Security.
2. Go through each permission category: Location, Contacts, Microphone, Camera, etc.
3. Tap each app and select “Allow only while using” or “Deny” where possible.
4. Under Network & Internet, restrict background data and disable Wi-Fi and Bluetooth scanning.
5. In Notifications, manage lock screen notification visibility.
6. Search “Usage & diagnostics” and turn off reporting.
7. Remove unused apps—especially those with access to personal data.

Why This Matters

Most people underestimate how much personal data their phones transmit quietly in the background. Each adjustment above represents a tangible reduction in your digital “attack surface,” safeguarding you against not just hackers, but also intrusive advertisers and data brokers. Following these steps will make you harder to track, less likely to be profiled, and much less vulnerable if your device is ever lost, stolen, or infected with malware.

Take an hour today to harden your device. Your privacy and safety in the cyber world are worth it.

Following these recommendations will not just boost your digital privacy, but also enhance battery life and overall system performance. Cybersecurity isn’t a one-time action, but a habit—make these settings part of yours!
