How do I unlock a Samsung phone that asks for a PIN I never set?
Answer
This usually means a screen lock PIN was set earlier—sometimes during setup or after a previous owner—or the phone is stuck before you can reach recovery options. Try a short list of common setup PINs once, then use Android Recovery for a factory reset if you accept losing local data.
Before you start: stop right away if…
- A factory reset erases photos, messages, and apps stored only on the phone.
- Do not share unlock codes or pay anyone who contacts you unexpectedly claiming they can unlock the phone.
Follow these steps
Try common setup PINs once
On the lock screen, carefully try once each: 0000, 1234, the last four digits of the phone number, a birth year you may have used, or a PIN from a previous phone. Stop after one failed attempt per guess so you do not lock the device longer.
You should see: The phone unlocks, or you confirm none of the common PINs work.
Power into Android Recovery
Power the phone fully off. Hold the correct Power and Volume key combination for your model until the Android Recovery menu appears. If it returns to the PIN screen, keep the charger cable connected and try the same key sequence again.
You should see: You see the Android Recovery menu with options such as Wipe data/factory reset.
Select Wipe data/factory reset
Use the volume buttons to highlight Wipe data/factory reset, then use the power button to confirm. Confirm again only if you accept that apps and local files will be erased.
You should see: The phone wipes and reboots to the initial setup screens.
Complete setup and Google verification
Follow on-screen setup. If Factory Reset Protection appears, sign in with the Google account that was previously used on the phone—not a new account.
You should see: Setup continues and you can create a new screen lock you control.
Set a new lock you will remember
After setup, open Settings, then Lock screen or Biometrics and security, and set a new PIN or pattern you can recall.
You should see: The phone locks and unlocks with the new credential you chose.

Extra tips
What to look for: A lock screen that only allows emergency calls, plus whether Volume Up/Down and Power can reach Android Recovery with Wipe data/factory reset.
Before you change anything: Confirm this is your phone and that you know the Google account that was on it (Factory Reset Protection may ask for it after a wipe). Back up anything you can access from another device first—a factory reset erases photos, apps, and local files. Do not pay a stranger or enter codes from unexpected calls or texts. Stop if the screen asks you to delete data until you are ready to lose what is on the phone.
