Phone Privacy and Security Settings to Change First
On a new phone, change the settings that protect access to the device and your accounts first: use a strong screen lock, secure account recovery, enable automatic updates, and limit app permissions, location sharing, tracking, and lock-screen previews. The exact menu names vary between Android phones and iPhones, but the same principle applies: grant only the access an app needs, and review settings again after setup.
Start with the screen lock and account recovery
Your screen lock is the first barrier if a phone is lost or left unattended. Choose a long passcode or password that is hard to guess; avoid birthdays, repeated digits, and patterns that are easy to observe. A fingerprint or face unlock can make everyday use convenient, but keep a passcode enabled because biometrics do not replace it for every restart, recovery, or security check. Set the phone to lock automatically after a short period of inactivity.
Next, protect the account tied to the phone. An Apple Account or Google Account may control backups, app downloads, device location, and password recovery, so losing access can affect more than the handset itself. Use a unique account password and turn on two-step verification or the account provider’s equivalent. Review trusted devices, recovery email addresses, phone numbers, and available recovery methods; remove anything you no longer control.
Save recovery codes in a secure place separate from the phone. A second factor stored only on the device you are trying to recover can create a problem if that device is lost. Set up a trusted alternate method where available, and keep the phone number on the account current.
Install updates and prepare for loss
Turn on automatic operating-system and security updates if the phone offers that choice, and install pending updates during setup. Updates can fix known security flaws as well as bugs. Also enable automatic app updates, or check the app store regularly if you prefer to approve them yourself. Some updates require Wi-Fi, charging, or a restart, so verify that installation has completed rather than assuming a download finished.
Enable the built-in lost-device service and confirm that it is associated with the account you control. These services can help locate, ring, lock, or erase a missing phone, subject to the device being powered on, connected, and configured appropriately. Check how to use the service before you need it. A remote erase is a last-resort protection for data, not a guarantee that a stolen device can be recovered.
- Use a secure backup, and check that it completes. A backup helps restore data after loss or failure, but it is not a substitute for a screen lock.
- Know how to contact your mobile carrier to suspend service if the phone and SIM are lost. Protect the account used to manage that service with a strong password and additional verification where offered.
- Keep the device’s emergency and medical information accurate if you choose to make it available from the lock screen; consider what information a stranger could see.
Limit app permissions and background access
Review permissions after installing or restoring apps. An app may request access to location, contacts, photos, microphone, camera, nearby devices, or notifications. Allow access only when it supports a feature you actually use. For example, a navigation app may need location while in use, while a simple flashlight app generally has no clear need for contacts.
Prefer options such as “while using the app,” selected-photo access, or one-time access when available. If an app needs a permission only for a particular task, you can grant it temporarily and revoke it afterward. Menu labels differ by operating-system version, but permission controls are usually grouped under Privacy, Security, or Apps in Settings.
Check background location separately from ordinary location permission. Some apps can request access even when closed; change this to allow access only while using the app unless ongoing access is genuinely necessary. Also review microphone and camera indicators, background activity, and notification access. Uninstall apps you no longer use, since removing them also removes their ongoing access to phone data.
Reduce location sharing, tracking, and data collection
Review system location services and the list of apps allowed to use location. Precise location can be important for turn-by-turn directions, while approximate location may be enough for local recommendations or weather. Disable location access for apps that have no useful location-based feature. Remember that turning off a location setting may affect functions such as finding a lost phone or sharing directions, so understand the trade-off before switching off a system-wide service.
Look for advertising, analytics, and tracking controls in both the phone’s privacy settings and individual apps. You can usually limit personalized advertising or restrict an app’s tracking across other companies’ apps and websites. These controls do not make you anonymous: services may still collect information needed to operate, and websites can use other methods to recognize activity. Review app privacy disclosures and account settings when deciding whether a service is worth using.
Check which apps can access photos, contacts, and calendars, and whether the system provides a privacy report or permission history. That history can help identify an app accessing sensitive features unexpectedly. Be cautious about granting access to an entire photo library when a few selected images are enough.
Hide sensitive information on the lock screen
Notifications can reveal message previews, verification codes, appointment details, and other private information to anyone who can see the locked screen. Set previews to appear only after unlocking, or turn off lock-screen notifications for sensitive apps. You can still receive an alert without displaying its contents.
Review quick actions and features available while the phone is locked. Depending on the device, options may include access to a digital assistant, reply actions, payment features, or control-center settings. Keep only the functions you find useful. Also consider whether a work profile, shared tablet, or family account needs separate controls; a personal phone used for work may be subject to organizational management settings that you should understand before changing them.
Connect carefully to networks and accessories
Use a personal hotspot or a trusted network for sensitive tasks when possible. Public Wi-Fi is not automatically unsafe, but an unfamiliar network can be operated by someone else, and a network name alone does not prove it is legitimate. Avoid dismissing certificate or security warnings. A reputable VPN may protect traffic on some networks, but it does not make every app trustworthy or prevent account-based tracking.
Turn off automatic joining for networks you no longer trust, and remove saved networks you do not use. Review Bluetooth and nearby-device access, especially for apps that do not need it. Pair accessories only when you recognize them, and remove old pairings you no longer use. Do not install configuration profiles, device-management tools, or apps from an unfamiliar source just because a pop-up claims they are required.
Common setup mistakes to avoid
A frequent misconception is that a new phone is private by default. Setup may restore old apps and permissions, enable cloud features, or prompt you to share diagnostics and personalized recommendations. Read prompts rather than tapping through them, and distinguish optional data sharing from settings needed for a feature you want.
- Do not reuse your phone passcode as an account password.
- Do not grant every permission during setup and assume you will remember to revisit it; review permissions once the essential apps are installed.
- Do not turn off all updates to save time. Security fixes are important, though you can choose a convenient time and keep the device charged.
- Do not assume a VPN, private-browsing mode, or ad-tracking control hides all activity from apps, account providers, or network services.
Settings are not a one-time task. Repeat a privacy check every few months and after installing a major update, restoring a backup, or adding a new account. If a menu name differs, search Settings for terms such as “permissions,” “location,” “lock screen,” or “updates,” then verify the description on your device.
Frequently Asked Questions
What is the most important setting to change on a new phone?
Set a strong screen lock and secure the account used to manage the phone with a unique password and two-step verification. These protect the device and its recovery options.
Should I turn off location services completely?
Usually, it is more practical to limit location access app by app. Allow it while using features that need it, and consider approximate location where precise location is unnecessary.
Are phone biometrics safer than a passcode?
Biometrics are convenient, but they work alongside a passcode rather than replacing it. Use a strong passcode and understand how your phone’s biometric and lock-screen settings behave.
Do I need a VPN on my phone?
Not everyone does. A VPN can protect some network traffic from other users on a local network, but it shifts trust to the VPN provider and does not stop all tracking or phishing.
How often should I review privacy settings?
Review them after setup and major updates, then periodically—such as every few months—or whenever you install an app that requests sensitive access.
