Tracer’s Phone Lockdown: The Step-by-Step Guide to Securing Your New iPhone or Android

At FindASpy headquarters, Tracer was enjoying a fresh French press when his big, lovable dog launched a one-dog mission for the kitchen counter.

The target was a biscuit.

The collateral damage was Tracer’s iPhone.

The phone bounced once, slid across the counter, and landed directly in a full glass of sweet tea. The screen went dark. Permanently.

“Captain Waffles,” Tracer said, looking at the dog, “you have defeated technology with carbohydrates.”

With a brand-new phone in hand, Tracer began setting everything up again. Then he paused.

“Since I’m reconfiguring security on mine, why not show you how to do yours?”

Whether your phone is new or several years old, this guide will walk you through a practical lockdown. No technical background is required.

Important scam and safety note: Apple, Google, your bank, and your mobile carrier do not need your screen passcode or one-time verification code. Never share those details with someone who calls, texts, or emails you unexpectedly. If a message tells you to install an app, click a link, or “verify” your account immediately, stop and independently contact the company through its official website or phone number.

Why Your Phone Needs a Security Check

Most phones arrive convenient first, private second. The default settings make setup easy, but some also share more location, usage, advertising, or account information than you may want.

We are going to work in this order:

  1. Update the phone.
  2. Lock the screen.
  3. Protect the Apple or Google account.
  4. Set up strong passwords.
  5. Limit unnecessary privacy access.
  6. Turn on theft and recovery protections.
  7. Add optional security apps.
  8. Build safer daily habits.

The menu names may vary slightly by phone model and operating-system version. If a setting has moved, use the Settings search bar and type the feature name.

1. Update Before You Do Anything Else

An operating-system update is a software repair from Apple, Google, or the phone manufacturer. Updates often fix known security weaknesses that criminals already understand.

A new phone can still contain an older version of the operating system, so update it before adding banking apps, email accounts, or sensitive information.

On iPhone

Go to:

Settings > General > Software Update

Install any available update. You may need to connect to Wi-Fi and charge the phone first.

Then update your apps:

App Store > your profile picture > App Updates > Update All

You can also review automatic updates under:

Settings > Apps > App Store > App Updates

On Android

On most Android phones, go to:

Settings > System > Software update

On Samsung Galaxy phones, go to:

Settings > Software update > Download and install

Then update your apps:

Google Play Store > profile picture > Manage apps & device > Update all

2. Lock the Screen Properly

The lock screen is the barrier that appears before someone can use your phone. It protects your messages, photos, email, saved passwords, banking apps, and personal conversations.

iPhone screen security

Go to:

Settings > Face ID & Passcode
or
Settings > Touch ID & Passcode

Choose Turn Passcode On or Change Passcode. Tap Passcode Options, then choose Custom Alphanumeric Code.

An alphanumeric code uses both letters and numbers. It is stronger than a short numerical code. Choose a long passphrase that does not use your birthday, address, pet’s name, or another fact someone could learn from social media.

Face ID or Touch ID is convenient, but your passcode is the real master key. Never share it.

On the same screen, turn on Stolen Device Protection. This feature adds biometric requirements and, for certain sensitive changes, a security delay. It helps stop someone who knows your passcode from changing your Apple Account password or disabling Find My.

Apple explains this feature in its official Stolen Device Protection guide.

Also under Settings > Privacy & Security, review Lockdown Mode.

Lockdown Mode is Apple’s extreme protection setting for people who may be targeted by sophisticated spyware or state-level attackers. When it is on, it deliberately blocks many normal phone functions to stop attacks. Most attachments and link previews in Messages are blocked. Most web technologies are disabled, which means some websites load slowly or do not work correctly. Incoming FaceTime calls from people you have never called are blocked. Connecting the phone to a computer or accessory also requires unlocking the phone first.

To find it, go to:

Settings > Privacy & Security > Lockdown Mode > Turn On Lockdown Mode

Then confirm with your passcode.

Most ordinary users do not need Lockdown Mode every day because it trades away convenience for extreme safety. But if you believe you are being targeted by spyware, a stalker with technical skills, or a sophisticated attacker, it is worth considering.

On Android, the closest equivalent is not one single switch. Instead, Google offers Advanced Protection for high-risk Google accounts:

Google Account > Security > Advanced Protection

That works alongside the Theft Protection tools already covered later in this guide. In short, Lockdown Mode makes sense for high-risk iPhone users, and Advanced Protection makes sense for high-risk Google accounts. Everyday users can usually skip both unless they have a specific reason for extra-hard protection.

Android screen security

Go to:

Settings > Security & privacy > Device unlock
or
Settings > Security & privacy > Screen lock

Choose Password for the strongest option, or use a long PIN of more than six digits. Avoid simple patterns and repeated numbers.

Fingerprint or face unlocking is useful, but do not treat it as a replacement for a strong screen lock. The PIN or password is still important.

3. Protect the Main Account

Your Apple Account or Google Account controls much more than email. It may protect your backups, photos, payment methods, contacts, app purchases, and location features.

iPhone: Apple Account and iCloud security

Apple now uses the term Apple Account instead of Apple ID. Your existing Apple ID email address and password still work.

Go to:

Settings > your name > Sign-In & Security > Two-Factor Authentication

Two-factor authentication means a second step proves that you are really you. That step may be a code, a trusted device approval, or another approved method.

Make sure it is on. Add a trusted phone number and consider adding a recovery contact.

Your Apple Account password should be:

  • Long, preferably a memorable passphrase.
  • Unique to Apple.
  • Unrelated to your name, birthday, address, or family.
  • Stored in a password manager instead of written beside the phone.

This password guards iCloud photos, messages, backups, payment details, and more. For instructions on changing it, see Apple’s official account-password guide.

Also consider setting a separate Screen Time passcode:

Settings > Screen Time > Lock Screen Time Settings

This creates another barrier around certain account and content settings.

Turn on Find My:

Settings > your name > Find My > Find My iPhone

Turn on Find My iPhone, Find My network, and Send Last Location. These features help you locate or protect the phone if it is lost or stolen.

Android: Google Account security

Go to:

Settings > Google > Manage your Google Account > Security > 2-Step Verification

Turn on 2-Step Verification and add recovery options, including a recovery phone number and recovery email address.

Your Google password protects Gmail, Android backups, Google Photos, Google Pay, and often the password-reset process for other accounts. Use a long, unique password and store it in a password manager.

Turn on Find My Device:

Settings > Security & privacy > Find My Device

The exact location may differ by manufacturer. Find My Device helps you locate, lock, or erase a lost Android phone.

4. Use a Password Manager

A password manager is an encrypted vault that creates and remembers strong, unique passwords for your accounts. You only need to remember one master password.

On iPhone, use the built-in Passwords app or iCloud Keychain. Depending on your software version, find it under:

Settings > your name > iCloud > Passwords & Keychain

Allow it to suggest strong passwords when you create new accounts.

On Android, use Google Password Manager through:

Settings > Google > Password Manager

It can suggest and save passwords in Chrome and compatible apps.

Never reuse a password. If one website suffers a breach, a unique password prevents criminals from using that same password everywhere else.

When a website offers a passkey, consider using it. A passkey is a passwordless login that uses your face, fingerprint, or device unlock instead of a typed password.

Optional password managers that work across iPhone and Android include Bitwarden, 1Password, NordPass, and Proton Pass. Review the current pricing and features before choosing one.

5. Limit Privacy Settings

iPhone privacy checks

Go to:

Settings > Privacy & Security > Tracking

Turn off Allow Apps to Request to Track. This limits an app’s ability to follow your activity across other apps and websites for advertising.

Next review location access:

Settings > Privacy & Security > Location Services

Set most apps to While Using or Never. An ordinary flashlight app does not need your location.

At the bottom, review System Services > Significant Locations. Turn it off if you do not want the phone remembering places you frequently visit.

For analytics, go to:

Settings > Privacy & Security > Analytics & Improvements

Turn off sharing options you do not want to provide.

For Mail, turn on Protect Mail Activity. This limits the ability of email senders to see when you open messages and helps hide your IP address.

In Safari, turn on:

  • Prevent Cross-Site Tracking
  • Fraudulent Website Warning

Android privacy checks

Go to:

Settings > Security & privacy > Privacy > Permission manager

Permissions are requests for access to your camera, microphone, contacts, files, or location. Review each category and deny access that an app does not need.

Then review:

Settings > Location

Set apps to While using the app or Ask every time where available.

To reduce advertising tracking, look under:

Settings > Privacy > Ads

Choose Delete advertising ID if the option is available.

On Samsung phones, review:

Settings > Connections > Wi-Fi > Intelligent Wi-Fi

Turn off automatic switching or intelligent features if you do not want the phone connecting automatically to saved networks.

Also review the radios and connections you leave running when you do not need them.

Radios and connection settings to turn off when not using them

These features are useful, but if you leave them on all the time, they can expose the phone to unnecessary connections, drain battery, or make it easier for the phone to interact with nearby devices and networks you did not intend to use.

Bluetooth is a short-range radio that lets devices like earbuds, speakers, keyboards, and car stereos connect to the phone. Leaving it on lets nearby devices see and sometimes connect to the phone, and criminals use cheap tools to send unsolicited messages or probe nearby Bluetooth devices.

Turn Bluetooth off when you are not using it.

On iPhone:

Swipe down from the top-right corner > Control Center > tap the Bluetooth icon
or
Settings > Bluetooth > Off

On Android:

Swipe down twice from the top > Quick Settings > tap the Bluetooth tile
or
Settings > Connections > Bluetooth > Off

Wi-Fi connects your phone to wireless internet networks. When you are away from home, turn Wi-Fi off if you do not need it so the phone does not automatically connect to unfamiliar networks.

On iPhone:

Swipe down from the top-right corner > Control Center > tap the Wi-Fi icon

Important note: on iPhone, Control Center only disconnects Wi-Fi until tomorrow. To fully turn it off, go to:

Settings > Wi-Fi > Off

On Android:

Swipe down twice from the top > Quick Settings > tap the Wi-Fi tile
or
Settings > Connections > Wi-Fi > Off

Airplane Mode turns off all radios at once, including cellular, Wi-Fi, and Bluetooth. It is useful on a plane, during troubleshooting, or anytime you want total radio silence with one switch.

On iPhone or Android, use:

Control Center or Quick Settings > Airplane Mode
or
Settings > Airplane Mode

NFC stands for near-field communication. It is the chip that lets the phone make contactless payments and share data when tapped against another device. It only works within a few inches, but if you want to be extra careful that a payment terminal or thief with a reader cannot tap your phone, turn it off when you are not paying.

On iPhone, there is no simple NFC off switch, so the safer habit is to keep the phone locked when not in use and consider a card sleeve for payment cards.

On many Android phones, go to:

Settings > Connections > NFC and contactless payments

You may also be able to turn off contactless payments inside your wallet app.

Mobile data is the phone’s internet connection through your cellular carrier. Turning it off while you are on Wi-Fi helps stop apps from using cellular data in the background.

On iPhone:

Settings > Cellular > Cellular Data > Off

On Android:

Settings > Connections > Data usage > Mobile data > Off

Some phones also offer a setting to block 2G under:

Settings > Connections > Mobile networks

2G is an old cellular technology with weaker security. Disable it where your phone and carrier provide the option.

6. Turn On Theft and Safety Protection

On iPhone, consider Advanced Data Protection for iCloud:

Settings > your name > iCloud > Advanced Data Protection

This encrypts more iCloud information end to end, meaning only your trusted devices and recovery methods can unlock it. Set up a recovery contact or recovery key first. If you lose both your account access and recovery method, Apple may not be able to recover that protected data.

On Android, look for:

Settings > Google > All services > Theft protection

Turn on available features such as:

  • Theft Detection Lock: locks the phone if it detects a likely snatch-and-run.
  • Offline Device Lock: locks the phone when it remains disconnected under certain conditions.
  • Identity Check: requires biometrics for high-risk account or security changes on supported devices.

Also verify Google Play Protect:

Google Play Store > profile picture > Play Protect > Settings

Keep Scan apps with Play Protect turned on. Google says Play Protect checks apps for harmful behavior and may warn you, disable an app, or remove it. Read more in Google’s official Play Protect guidance.

7. Optional Security Apps

Only install apps from the official Apple App Store or Google Play Store. Check the developer name. Never install an app because a pop-up, unexpected caller, or text message tells you to.

Useful optional layers include:

  • Password manager: Bitwarden, 1Password, or Proton Pass.
  • VPN: A virtual private network encrypts your internet connection, especially on public Wi-Fi. Consider Proton VPN, NordVPN, or ExpressVPN. You need one reputable VPN, not several.
  • Authenticator app: Google Authenticator or Microsoft Authenticator creates login codes without depending entirely on text messages.
  • Android security scanner: Bitdefender and Malwarebytes offer Android security versions. Android allows more installation from outside official stores, so scanning can provide an additional layer.

Traditional antivirus is generally unnecessary on iPhone because of Apple’s app restrictions and built-in protections.

If you believe your phone is already compromised, do not keep experimenting with suspicious apps. FindASpy’s Guardian Angel spyware and breach removal service can provide a deeper review. Call 321-342-0040 for assistance.

8. Tracer’s Final Phone Habits

Tracer finished his new-phone setup in about an hour. Captain Waffles supervised from a safe distance, away from all beverages.

Before you put your phone back in your pocket:

  • Turn on automatic operating-system and app updates.
  • Back up your phone to iCloud or Google One.
  • Lock the phone whenever you set it down.
  • Never share your passcode or one-time verification code.
  • Never approve a login you did not start.
  • Be suspicious of calls claiming to be Apple, Google, your bank, or your carrier.
  • Independently verify unexpected requests using an official website or a trusted phone number.

You can follow this checklist on an old phone, too. It is never too late to strengthen your privacy.

Before we wrap up, there is one more set of tools worth turning on. They do double duty: they build healthier phone habits and quietly lock the front door against anyone who picks up your unlocked phone.

9. Screen Time and Digital Wellbeing Setup

These built-in tools show you how much you use your phone, help limit distracting apps, and add another layer of protection around important settings.

iPhone: Screen Time setup

Go to:

Settings > Screen Time > Turn On Screen Time > This is My iPhone

Then set a separate Screen Time passcode:

Settings > Screen Time > Use Screen Time Passcode

This is a different 4-digit code from your regular screen passcode. It stops anyone, including a thief or a curious child, from changing your Screen Time settings without that extra code.

Once that is set, review these options:

  • App Limits: Set a daily time limit on social media or game apps so the phone asks for the passcode when time is up.
  • Downtime: Schedule hours, such as 10 p.m. to 7 a.m., when only the apps you choose remain available.
  • Communication Limits: Choose who can contact you during Downtime.
  • Always Allowed: Pick essential apps such as Phone, Messages, and Maps so they stay available during Downtime.

Now open the most overlooked security feature in this section:

Settings > Screen Time > Content & Privacy Restrictions

Turn it On, make sure your Screen Time passcode is set, and use these controls to:

  • Block explicit content.
  • Stop app installs and deletions.
  • Prevent account changes.
  • Prevent changes to location, contacts, and other privacy settings.

For app installs specifically, go to:

Settings > Screen Time > Content & Privacy Restrictions > iTunes & App Store Purchases > Installing Apps > Don't Allow

This is the hidden gem most people never find. It is basically a parental control that you can use on your own phone. Even if someone picks up your unlocked phone, they cannot install apps, delete apps, or change your privacy settings without that separate Screen Time passcode.

Android: Digital Wellbeing setup

Go to:

Settings > Digital Wellbeing & parental controls

Inside, you will usually find:

  • Dashboard: A ring chart showing how much you use your phone by app.
  • App timers: Set a daily limit per app. When time runs out, the app icon goes gray.
  • Focus mode: Pauses distracting apps for a set period.
  • Bedtime mode: Silences the phone and fades the screen to grayscale on a schedule.
  • Parental controls: Connects to Family Link if you need to manage a child’s device.

For the Android security equivalent, also check your regular phone settings for app install restrictions. The exact path varies by phone maker, but look under:

Settings > Security & privacy > More security & privacy
or
Settings > Apps > Special app access

On Samsung phones, similar options may also appear under app-management settings. Use those restrictions along with the Permission manager already covered earlier to stop apps from reaching sensitive data they do not need.

Lesson

A secure phone is not created by one magic app. It is built through layers:

Awareness helps you recognize unusual requests.
Knowledge helps you find the right settings.
Protection makes the phone harder to misuse if it is lost, stolen, or targeted.

Coffee Challenge

Before your next cup of coffee:

  1. Check for operating-system updates and install them.
  2. Review your screen lock and account two-factor authentication.
  3. Open your app permissions and remove access that does not make sense.
