Your Android phone concentrates a large part of your digital life: photos, conversations, documents and passwords And much more. Although the system has significantly strengthened its security on Android, there's always room for fine-tuning settings that give you more control over what you share and with whom. In this guide, we'll go over, in detail, what you should disable or adjust to increase privacy without breaking key phone functions, and which options you shouldn't touch to maintain protection.
Before we dive in, it's helpful to remember that absolute privacy doesn't exist. Even with all the fine-tuned settings, certain apps, services, and websites can still collect data through other means. Still, with the changes below, you can close unnecessary doors, minimize tracking, and strengthen your daily security. The key is to choose what to disable and what to keep active so as not to sacrifice important features..
Check your status in 'Security & Privacy' on Android
The central section for all of this is in Settings > Security & Privacy. On some manufacturers, the security and privacy options appear separate, but the idea is the same: here you'll see a dashboard with the overall status of your device. If there are no alerts, an 'All OK' message usually appears; if something requires attention, you'll see warnings with the risk and a suggested correction..
From this panel, you can start a basic scan with options like screen lock, biometric unlock, app scan, and other essential requirements. When something is pending, it will be marked in red and you can go directly to its settings to activate or modify it..
Privacy Dashboard: What permissions your apps use
Under Security & Privacy > Privacy, you'll find the Privacy Dashboard, which shows which permissions have been used in the last 24 hours. You'll see a summary graph, and below that, lists by permission type. By tapping on a permission you can see which apps requested it and when, and from 'Manage permission' you can revoke or adjust their access..
This panel is perfect for detecting unusual behavior: if a permission appears more than expected, something may be abusing it. Use this view as a frequent audit to keep unnecessary access at bay..
Permission Manager: control one by one
Under Security & Privacy > Privacy > Permission Manager, you'll find a complete list of available permissions and which apps can use them. Depending on the permission, you can choose to not allow it, allow it only while the app is in use, ask every time, or grant access permanently. Remember that if you remove an essential permission, certain apps will no longer offer specific functions..
This is the list of the most common permissions you can manage in Android 14 and current layers: adjust them head-on and in a granular way.
- Physical activity: access to movement data for health and sports apps.
- Files: Read/Write device storage.
- Calendar: view and create events.
- Camera: Use the sensor for photos and video within apps.
- Contacts: reading and using your address book.
- Nearby devices: detection and connection to nearby devices.
- Photos and video: Access your stored media.
- Microphone: Audio recording and listening for attendees or notes.
- Music and audio: access to audio and music files.
- Notifications: Permission to read/show notifications.
- Call log: reading call history.
- Connected Health: Health data hub for compatible apps.
- Body sensors: use of biometrics and related sensors.
- SMS: reading messages (e.g. OTP codes).
- Telephone: making and managing calls.
- Location: GPS data; configurable as precise or approximate.
- Additional permissions: manufacturer-specific or less common functions.
Gives access to only some photos (Android 14)
When an app asks for permission to view Photos and Videos, you can grant full access, deny permission, or select only specific items. This option is very useful, for example, for posting an image on a social network without giving away your entire gallery. If you've already given full access, change the permission to 'Always ask' and next time, choose only the necessary photos..
Precise vs. approximate location
For apps that don't need to know your exact location, disable the precise location option within the Location permission for that specific app. This way, the app will see a general area, but not your street address and number. Reserve the exact location for car navigation, routes or services that really require it..
Centralize access to your health data
Under Privacy > Connected Health, you can manage which apps read or write health data in the Android 14 health center. You'll see which apps have permission, which don't, and you can revoke or adjust their access whenever you want. It's a good idea to review this list periodically, especially if you install new fitness or health apps..
Enhanced PIN Privacy: Disables typing animations
In Settings > Security & Privacy > Device Unlock > Screen Lock (gear icon), you'll find Enhanced PIN Privacy. When enabled, the number animations disappear while you enter your PIN. It seems like a minor detail, but it reduces the risk of prying eyes or screen recordings giving away your sequence..
Complete cut to camera and microphone with one touch
From Security & Privacy > Privacy, you can disable the Camera Access and Microphone Access switches. While these are off, no app can use these sensors, even if it has been granted permission. It is ideal for sensitive meetings or environments where you don't want risks..
Hide passwords as you type them
In the same Privacy menu, turn off Show Passwords to prevent the last character of your password from being displayed for a few moments. This reduces the risk of malicious applications trying to record your screen or people looking over your shoulder..
Notifications on the lock screen
Go to Settings > Notifications > Lock Screen Notifications and choose whether to show everything, hide it completely, or limit conversations. If you often leave your phone in plain sight, locking the content is a great idea. Prevents anyone from reading messages without unlocking the device.
Minimize what you send to Google
Under Security & Privacy > Privacy > Account Activity Controls, you can turn off web and app activity logging, location history, YouTube history, and ad personalization. Disabling these points reduces your Google account footprint..
Additionally, under Privacy > Ads, you can manage your advertising ID and reset it or limit personalization; and under Security & Privacy > More security & privacy, you'll find Personalize using app data to prevent Android from using data shared by other apps, along with Usage & Diagnostics to stop sending usage and stability metrics. Disabling 'Usage and Diagnostics' is one of the most direct measures to cut telemetry.
Native Google services worth checking out
In Settings > Google, you'll see a long list of services. Not all of them are critical; you can disable some if they don't provide any benefit. These are the most relevant ones that you should check one by one:
- COVID-19 Exposure Notifications: Deprecated for Most Today
- Google App Settings: Control permissions and data for Google and linked third-party apps.
- Ads: Limit or disable personalized advertising.
- Autofill – useful for autofilling SMS codes; Activate it only if it's worth it to you.
- Setup & Restore: Options to restore contacts or set up work profiles.
- Parental Controls: Family Link for Kids and Teens.
- Device and sharing: Integrate services like Chromebook or Google Cast.
- Emergencies: Manage driving mode to silence distractions.
- Find My Device: Essential for locating, locking, or erasing your lost phone.
- make backup On Android: backups of apps, calls, contacts, settings, photos, and SMS.
- Game Panel: You can disable it if you are not using it.
- Personalize with shared data: Allows other Google apps to use app data from your device; turn this off if you prioritize privacy.
In Google Apps Settings > Connected apps, you can see which third-party apps have access to your account, what data they see, and unlink them. Clean periodically to remove connections that you no longer use..
Search, Assistant, and Voice: What to Cut
Within Google > Google App Settings > Search, Assistant & Voice you have several areas to reduce data noise:
- General: Turn off recent pages, personal results, and trending autocomplete if you don't want them.
- Notifications: Turn off reminders, proactive alerts, weather, or scrolling if they bother you.
- Safe Search: Activate the explicit results filter if you are interested.
- Personal results: Limit information extracted from your account in searches.
- Personalization: Adjust interests for more discreet suggestions or choose to reduce them.
- Google Assistant: Access routines, personal results, reminders, and "You" data (addresses, contacts, sources, etc.).
- Voice: Set languages, filter out profanity, and for more privacy, turn off OK Google detection. Preventing background listening reduces accidental captures.
- Language and region: Adjust how the assistant responds.
- Privacy and security on Android: Review what personal data is used for ads.
- Information: terms, policies, and licenses, in case you need to consult them.
Find My Device: Should I turn it off or not?
From Security & Privacy > Device Finder, you can disable the feature that allows you to locate your phone. Doing so increases your privacy from Google, but you'll lose the ability to find it, lock it, or erase data if it's lost or stolen. It is not recommended to disable it unless you seek maximum privacy and accept that risk..
Google Play Protect and sample submission
Play Protect scans apps and games from the Play Store and can submit anonymous samples to identify malware and threats. Disabling sample submission reduces data sharing with Google, but also reduces the ability to detect new threats. In general, it is not recommended to disable this system or its sample delivery if you want to maintain a good level of security on Android.
Private DNS and VPN: An Extra Layer of Privacy
Setting up a private DNS or using a VPN can help avoid carrier blocks, mitigate IP tracking, and improve the security of your Android connections. Android allows you to set a private DNS in Network Settings and choose providers with strong privacy policies. A reliable VPN also hides your IP and encrypts your traffic, ideal for public networks..
Manufacturer's own settings
Depending on the manufacturer (Samsung, Xiaomi, etc.), there may be additional settings and option relocations. Some add secure Wi-Fi, native app locks with PIN or fingerprint, or new security panels on Android. Take a few minutes to explore the privacy section of your layer to take advantage of specific features and limit the sending of statistics to the manufacturer..
Phone lock and app lock
Beyond permissions, the first barrier is locking your device with a PIN, pattern, fingerprint, or face. Activate it in Security & Privacy > Device Unlock. Without a good initial block, the rest of the measures lose much of their value..
Some layers allow you to block apps with a PIN or biometrics from Settings, and many apps (such as WhatsApp) have their own lock. Use it in sensitive apps to add an extra barrier if someone unlocks your phone..
Secure WiFi networks and warnings
Connect only to trusted networks. Android and iOS warn you if a network is potentially unsafe. Avoid entering passwords or sensitive data on public Wi-Fi without a VPN. If your manufacturer offers 'Secure Wi-Fi' or suspicious activity alerts, turn them on..
Password manager and leak detection
Android and your Google account can alert you if a saved password appears in a known breach. Go to Settings > AutoFill > Passwords and run the check. Immediately change compromised credentials and enable 2FA whenever possible..
Google Account: Security Checkup on Android
In Settings > Google > Manage Google Account > Security, you'll find a centralized overview of your account, connected devices, logins, and recommendations. Complete this check to plug holes beyond the phone.
Disable 'Usage and Diagnostics' if you don't want telemetry
To stop sending usage statistics to Google, go to Settings > Privacy > Advanced > Usage & Diagnostics and turn it off. This measure reduces the sending of data such as battery consumption, app activity and system metrics..
Emergency information on the lock screen
Add relevant medical information or an emergency contact so it's visible without unlocking your device. This can help in the event of an accident or loss of your device. It's a simple adjustment that adds a lot of value in critical situations..
If you lose your phone: lost mode and location
If your device is lost or stolen, go to Find My Device from a browser, log in, and locate it. You can also ring it, lock it, or erase its contents. This tool is essential; keeping it active is the best insurance against scares..
Camera and microphone permissions: keep a close eye on them
Manage which apps can use the camera and microphone in Privacy > Permissions Manager. At the top of Android, you'll see indicators when they're in use. If an app appears without reason, review it and cut off access until you understand why it is requesting it..
Tracking control and personalized ads
On Android, you can disable ad personalization by going to Google Settings > Ads and, additionally, limiting personalized results in the search engine. The less cross-platform your advertising profile is, the less exposure to tracking between apps and services..
Good practices beyond adjustments
Don't install apps from unknown sources, keep your system updated, and be wary of permissions that don't match the app's function. Check app descriptions and reviews before installing. For browsing and searching, consider privacy-focused options if Google features aren't essential for you..
On social media and online communities, always consider what information you share and with whom. Adjust your account privacy settings and limit public data. What you post may become easily accessible to third parties, even if you initially shared it in a limited environment..
With all of the above, you'll have a robust setup that reinforces your privacy without losing key features. The combination of strong locking, fine-tuned permissions, reduced telemetry, and critical features like Play Protect and Find My Device enabled leaves you with a very balanced balance between security and convenience.
