Lost Your Android Phone? How to Find, Lock or Erase It

By Ammar Aslam · Updated September 29, 2026 · 3 min read

Losing your phone is stressful, not just because of the cost, but because of everything on it. Google's Find My Device helps you locate, lock or erase an Android phone from any computer or another phone. The key is to set it up before you need it.

Set it up now

Go to Settings → Google → All services → Find My Device (or Settings → Security).
Make sure Find My Device is on.
Turn on Location.
Enable Find your offline devices if available, so the phone can be found through the network of other Android devices even without internet.
Test it by visiting the Find My Device website while signed in.

Samsung phones also offer SmartThings Find for extra options.

When your phone is lost

On a computer or another phone, go to google.com/android/find or open the Find My Device app, and sign in with the same Google account. You can then:

Option	What it does
Play sound	Rings loudly for 5 minutes, even on silent
Secure device	Locks the phone and shows a message or number on screen
Factory reset device	Erases everything; you can no longer locate it afterwards

If you think it was stolen

Don't try to recover it yourself. Share the location with the police.
Lock the device right away with Secure device.
Call your mobile network to block the SIM and get a replacement with the same number. This stops misuse of your number for OTP codes.
Change passwords for your Google account, email and banking apps from another device.
Inform your bank if banking apps were on the phone.
Report the phone's IMEI number to the relevant authority in your country for blocking.

Find your IMEI now

Dial *#06# to see your IMEI and save it somewhere safe, along with your phone's box and purchase receipt.

Protect your phone in advance

Use a strong screen lock and fingerprint. See lock screen security.
Enable SIM PIN lock.
Turn on theft protection features available on newer Android versions.
Keep regular backups so losing the phone doesn't mean losing photos.

What to do in the first 30 minutes

Acting quickly and calmly makes the biggest difference. Here's a priority list:

Call your number from another phone; it may be nearby or someone honest may answer.
Use Play sound if you think it's in your home, car or office.
Check its location and note the time and place.
Secure the device with a message and alternative contact number.
Retrace your steps: call shops, taxis or ride services you used.
Block the SIM through your network if you can't recover it soon.
Change passwords for Google, email, social media and banking.

Prepare today so recovery is easier tomorrow

Most people only think about this after losing a phone. Spend ten minutes now:

Test Find My Device from a computer while your phone is with you.
Save your IMEI number, phone model and receipt in a safe place (email them to yourself).
Add an emergency contact to your lock screen (Settings → Safety & emergency) so an honest finder can contact you.
Make sure photos and contacts back up automatically. See backup guide.
Write down your Google account password somewhere secure at home or in a password manager accessible from another device.
Protect banking apps with separate PINs or biometrics.

For families

You can help family members find their phones through Google Family Link or location sharing in Google Maps, with their consent. Setting this up for children and elderly parents gives peace of mind.

Frequently asked questions

Can I find my phone if it's switched off?

Find My Device shows the last known location. Some newer phones can be found while offline through the Find My Device network.

Can a thief reset my phone and use it?

Factory Reset Protection requires your Google account after a reset, which makes stolen phones much less useful.
