Secret Android Security Features You Should Be Using!
Android is packed with security features, but most users aren’t aware of the hidden settings that can protect their personal data, privacy, and online identity. Whether you’re worried about hackers, malware, or unauthorized access, tweaking Android’s built-in security options can significantly boost your device’s safety.
In this guide, we’ll unveil secret Android security features you should be using to keep your phone and data safe from cyber threats.
1. Enable the Built-in App Lock for Extra Security
Many Android skins, including Samsung One UI, MIUI, and OxygenOS, come with a hidden App Lock feature that allows you to lock specific apps with a PIN, pattern, or fingerprint.
Go to Settings → Security → App Lock (or search for it in your settings).
Select the apps you want to lock.
Set a PIN, pattern, or fingerprint for extra protection.
Why Use It? Even if someone has access to your phone, they can’t open sensitive apps like WhatsApp, banking apps, or email without your permission.
2. Use Android’s Hidden “Private DNS” for Secure Browsing
Did you know that Android allows you to use encrypted DNS for safer web browsing? Private DNS prevents your internet provider and third parties from tracking your online activity.
How to Enable Private DNS:
Go to Settings → Network & Internet → Private DNS.
Choose Private DNS provider hostname and enter:
Cloudflare DNS: 1dot1dot1dot1.cloudflare-dns.com
Why Use It? It helps protect against DNS spoofing attacks, improves privacy, and speeds up browsing.
3. Activate Android’s Built-in Anti-Theft Feature
Android’s Find My Device feature allows you to remotely lock, erase, or track your phone if it's lost or stolen.
How to Activate Find My Device:
Go to Settings → Security → Find My Device.
Enable Find My Device and sign in to your Google account.
Visit Google’s Find My Device to track your phone if needed.
Why Use It? This feature lets you remotely erase all data or lock the device if it falls into the wrong hands.
4. Enable “Safe Folder” to Hide Sensitive Files
The Safe Folder in Google Files app allows you to store confidential documents, private photos, and sensitive data behind a PIN-protected vault.
How to Set Up Safe Folder:
Open Google Files App → Tap Safe Folder.
Set a 4-digit PIN to secure it.
Move your personal files into the Safe Folder.
Why Use It? It ensures no one can access your personal files, even if they have your phone.
5. Prevent Apps from Tracking You with “Permission Manager”
Android allows you to restrict app permissions to stop apps from tracking your location, accessing your camera, or reading your messages without permission.
How to Manage App Permissions:
Go to Settings → Privacy → Permission Manager.
Review permissions for Location, Camera, Microphone, and Contacts.
Change settings to “Allow only while using the app” or “Deny” for better privacy.
Why Use It? Many apps abuse permissions to collect personal data. Limiting access improves privacy and security.
Android has powerful security features, but many remain hidden or unused by most users. Enabling these built-in security options can help you protect your data, enhance privacy, and keep your phone safe from hackers.
