4 Android security settings you should enable first

Android security – From ensuring Google’s Find Hub can still locate a phone offline to turning on newer Android 16 “Advanced Protection” controls, these are four security features that many Android users prioritize on day one—plus the practical trade-offs they bring.

The first thing I do after a new Android phone boots up is less about picking a wallpaper and more about making sure the device can survive the worst day of my life.

I sign into my accounts. remove what I don’t need. and then I move straight to security settings that often look “done” at a glance—but still need a check. Some protections come pre-enabled. Others require a toggle. The goal is simple: if a phone disappears in a crowded place. or if someone tries to get in through the wrong link. I want the phone to have every extra layer it can.

Find Hub: make sure it’s working before you need it

Find Hub is automatically enabled when you sign in with a Google account. People like it because it isn’t dependent on your phone having a working internet connection or GPS at the worst moment. If the phone goes offline, Find Hub can still locate it using Google’s crowdsourced network of Android devices. Once you need it. you can view your phone’s location on a map. make it ring. lock it remotely. or erase it entirely.

That’s why it lands at the top of many day-one checklists. Not because you have to enable it manually, but because it’s worth verifying it works while you still have the phone in your hands.

Many phones also add their own tracking. The Galaxy S26 used in this checklist includes Samsung’s Find My Mobile, which is also enabled by default. The specific optional feature that gets turned on there is Send last location. which automatically uploads the phone’s last known location when the battery is about to die.

Theft protection: catch account takeover, stop the “airplane mode” trick

The second priority is theft protection that kicks in when a phone is snatched and someone tries to run with it. Theft Detection Lock comes pre-enabled. It can detect the situation using a mix of on-device sensors, Wi‑Fi, Bluetooth, and AI.

But the most important part is what it adds around that core detection. This checklist enables Identity Check. which makes it harder for someone to take over the Google account linked to the phone by requiring biometric authentication for actions like using the “Forgot password” option or changing account recovery methods.

It also turns on Offline Device Lock. That feature automatically locks the phone if it’s disconnected from the internet for an extended period—handy because one of the first things a thief is likely to do is switch to airplane mode, which can otherwise prevent tracking through Find Hub.

The final optional toggle is Failed Authentication Lock. It locks the phone’s screen and sensitive apps when authentication attempts fail repeatedly. The point isn’t to stop a thief instantly; it’s to buy extra time so you can locate or erase the phone through Find Hub.

These optional theft-protection features are found under Settings > Google > All services > Theft protection.

Android 16’s Advanced Protection: stronger controls with real friction

Advanced Protection is newer—introduced with Android 16—and it’s disabled by default. The checklist turns it on anyway, despite the restrictions it can bring.

Advanced Protection doesn’t act like a single switch for one problem. Instead, it combines multiple protections into one setup. One example is Inactivity Reboot, which automatically restarts the phone if it’s been locked for three days straight. The other security change included here is that it blocks 2G networks on the phone. since 2G is generally less secure than 3G. 4G. and 5G.

To enable it, the checklist points to Settings > Security and privacy > Advanced Protection and then turn on Device Protection.

It also changes how Google apps behave. It enables safe browsing in Chrome, spam protection in Google Phone, and blocks unsafe links in Google Messages. It can also turn on live threat detection as part of the Android Safe Browsing feature. identifying and blocking phishing links and web pages in supported third-party apps—so the protection is not limited to Google’s own services.

The trade-off is sideloading. Advanced Protection blocks sideloading, which can be inconvenient for users who rely on apps not available on the Play Store. In that scenario, the checklist recommends temporarily disabling the feature whenever you need to install or update those apps.

SIM lock and two-factor authentication: extra defense for the phone number itself

SIM lock isn’t an Android feature in the strict sense, but it’s treated as essential in the same security routine. A SIM lock adds a layer of protection to a phone number by requiring a PIN whenever the SIM card is inserted into a new phone or the phone is restarted.

The reason is practical: if a phone is stolen, the last thing you want is someone moving your SIM to a different phone to receive calls and OTPs meant for you.

To set it up, the checklist directs users to Settings > Security and privacy > More security settings > SIM card lock.

The routine doesn’t stop there. It also insists on using two-factor authentication for important accounts, especially the Google account tied to the phone. The logic is straightforward—if someone gets access to that account. they could potentially track the device or even remotely erase it. Google Authenticator is the preferred method here because it’s generally more secure. but the guidance is that any form of 2FA is better than none. If you prefer authentication prompts or SMS verification, those should be used to keep important accounts protected.

Between “find and erase” tools and account-defense features, the checklist is trying to remove the most common gaps: the moment a phone goes offline, the moment a thief tries airplane mode, and the moment a stolen account could be used to control the device.

If there’s another Android security setting you always review on day one, this checklist invites readers to share it in the comments—because security routines are rarely identical, but the goal is the same: make the worst day harder to win.
