This article is based on tests conducted using an iPhone 15 Pro Max running iOS 18.5 and a Samsung Galaxy S24 Ultra with One UI 7.0 on Android 15. Results and instructions may vary depending on your device model and software version.

Because your phone shouldn't sell your behavior

Apps love your data, especially when it helps them target ads. On iPhone and Android, apps can track what you do across other apps and websites unless you say otherwise. Here's what to look for:

You keep seeing the same weirdly specific ad after searching for something once. Or you download a game, and suddenly ads know your location, interests and habits.

On iPhone:Settings > Privacy & Security > Tracking → Toggle off "Allow Apps to Request to Track."

On Android:

Settings may vary depending on your Android phone's manufacturer 

Settings > Google > All services > Ads → Turn off "Ad personalization" or choose "Delete advertising ID" for more privacy.

This won't block all ads, but it prevents apps from tracking your activity.

Because anyone can see your texts, even when your phone is locked

By default, many phones show message previews on the lock screen. Sounds convenient, until someone sees your two-factor authentication code, private message or bank alert over your shoulder.

You'll want to change this if:

On iPhone:Settings > Notifications > Show Previews → Set to "When Unlocked."

On Android:

Settings may vary depending on your Android phone's manufacturer 

Settings > Notifications > Lock Screen notifications → Choose "Hide content" or, on some Android phones, it might say "Don't show sensitive content" (which hides sensitive content like message previews on the lock screen).

You'll still get alerts, but what's inside stays private.

Because that flashlight app doesn't need your location

Over time, apps can quietly collect more permissions than they need, accessing your camera, microphone, contacts or even location without you noticing. You might be giving away too much if:

On iPhone:Settings > Privacy & Security → Tap Location Services, Camera, Microphone, etc. to see what apps have access.

On Android:

Settings may vary depending on your Android phone's manufacturer 

Revoke anything that doesn't make sense. Your phone will still work just fine.

Because hackers love an open connection

Bluetooth is great for headphones and smartwatches, but it's also a known entry point for cybercriminals using "bluesnarfing" or other attacks to siphon data. The risk goes up if:

Swipe down from the top right of your screen to access your Control Center (iPhone) or Quick Settings (Android), and toggle Bluetooth off (A blue stylized "B" symbol shaped by two angular runes resembling "ᛒ" joined vertically) when not in use. Less is more when it comes to open channels.

Because outdated phones are hacker magnets

Software updates don't just bring new features; they patch critical vulnerabilities that hackers rely on to break into phones.

Red flags:

On iPhone:Settings > General > Software Update > Automatic Updates → Enable both toggles.

On Android:

Settings may vary depending on your Android phone's manufacturer 

Settings >  Software Update > Auto-download or Auto-install updates (may vary by device)

One of the simplest, strongest defenses you can set.

You don't need a tinfoil hat to take phone security seriously, just a few quick changes to how your device behaves. Small things, such as hiding message previews, checking app permissions and disabling Bluetooth can make a big difference in protecting your personal information. And, remember, phone security isn't a one-time deal. Stay curious, keep your software updated and check in on your settings periodically, just as you would with your bank or email accounts.
