The five Android settings that protect you most against theft are: a 6-digit PIN or a password, Theft protection (Theft Detection Lock, Offline Device Lock and Failed Authentication Lock), Remote Lock, Find Hub and Identity Check. Together they lock a snatched phone, let you lock or locate it from another device, and stop a thief from turning your protection off. They’re all free and built into Android. Turn them on now; most take less than a minute. What none of them do is show you who tried to get into your phone, which is where an app like CrookCatcher comes in.
1. Use a strong screen lock
Everything else depends on your screen lock. If a thief can guess it, every other setting can be switched off.
- Use a 6-digit PIN or a password, not a 4-digit PIN. A 4-digit PIN has 10,000 possible combinations; a 6-digit PIN has 1,000,000.
- Avoid easy codes like 1234, 0000, 1111 or your birthday.
- A pattern is the weakest choice. People often draw simple shapes, and patterns are easy to watch over your shoulder.
On a Pixel, go to: Settings > Security & privacy > Device unlock > Screen lock
On other phones, open Settings and search for “Screen lock”.
Fingerprint and face unlock are convenient, but you still need a strong PIN or password behind them. That’s what Android asks for after a restart and when your phone has locked itself down.
Recent Android versions also make guessing slow: after a few wrong guesses the phone makes the person wait, and the waits grow to days. Read what Android does with failed unlock attempts for the details.
2. Turn on Theft protection
Android’s Theft protection locks your phone automatically in the situations thieves rely on.
Go to: Settings > Google > All services > Theft protection
Turn on:
- Theft Detection Lock: locks the screen if your phone detects that someone snatched it and ran.
- Offline Device Lock: locks the screen soon after the phone goes offline, for example when a thief switches on airplane mode.
- Failed Authentication Lock: locks the screen when unlock attempts fail repeatedly. It’s on by default.
If a setting is grayed out, your phone doesn’t support it. These features need Android 10 or later, and some need Android 15 or later. On Samsung Galaxy phones, Samsung also has its own Theft protection menu; see how to see who tried to unlock your Samsung phone for where to find it.
3. Turn on Remote Lock
If your phone is stolen, Remote Lock lets you lock it from any browser at android.com/lock, using just your phone number. You don’t need your Google password, which helps if your passwords are saved on the stolen phone.
Go to: Settings > Google > All services > Theft protection > Remote Lock
Turn it on, and add the optional Security question so nobody else can lock your phone with only your number. Remote Lock needs the phone to have a SIM, be online and have Find Hub turned on.
4. Make sure Find Hub is on
Find Hub (formerly Find My Device) shows where your phone is on a map and lets you ring, lock or erase it from another device at google.com/android/find.
It’s usually on by default when you sign in with a Google account, but check: open Settings and search for “Find Hub”. Make sure it’s on and that location is allowed.
5. Turn on Identity Check
If a thief learns your PIN, for example by watching you type it, Identity Check stops them from turning off your protection. Away from places you trust, it asks for your fingerprint or face before sensitive actions like changing your screen lock, turning off Find Hub or Theft protection, or resetting the phone.
You’ll find it under Settings > Google > All services > Theft protection on phones that support it.
What these settings can’t do
These settings lock the phone and help you find it. They don’t tell you:
- Who tried to get into your phone. Android keeps no record and takes no photo.
- When it happened, or how many times.
- Where the phone was at that moment.
They also only help once the phone is gone. Most people want to know sooner: who picked up the phone while they were away, or who tried to guess their PIN.
Know who tried to unlock your phone
CrookCatcher fills that gap. When someone enters a wrong PIN, pattern or password, it takes a photo with the front camera, records the GPS location and an approximate address, and emails both to you. The photo and location are already in your inbox even if the phone is switched off a minute later, and you can share them with the police.
It has been downloaded more than 12 million times since 2014 and takes around 1.2 million intruder photos a day. Setup takes a few minutes: see how to see who tried to unlock your phone.
More ways to make your phone harder to steal
- Remove airplane mode from Quick Settings, so a thief can’t cut the connection with one swipe. See how to stop thieves from turning off your phone.
- Lock your SIM card with a PIN (
Settings > Security & privacy > More security settings > SIM lock), so a thief can’t use your number to receive your codes. - Hide notification content on the lock screen (
Settings > Security & privacy > More security settings > Notifications on lock screen), so security codes don’t show while the phone is locked. - Keep your phone updated, since new theft protection features arrive with Android updates.
