How do you unlock a Samsung phone that you cannot open?
Answer
Try the correct PIN, pattern, or password first; if that fails, use Samsung Find My Mobile unlock when enabled, or an official factory reset path knowing Google/Samsung account verification may still be required.
Before you start: stop right away if…
- Factory reset deletes on-device photos and messages that were not synced.
- Paid third-party unlock tools are frequently scams.
Follow these steps
Retry the known screen lock carefully
Enter the PIN/pattern slowly. If biometrics fail, look for a Use PIN/Password option after a few Face/Fingerprint misses.
You should see: The phone unlocks, or you confirm the credential is unknown.
Unlock with Find My Mobile
On another device, sign in to smartthingsfind.samsung.com with the Samsung account on the phone and choose Unlock if available.
You should see: Samsung removes the lock screen or lets you set a new PIN.
Factory reset only if remote unlock fails
Use recovery-mode factory reset for your Samsung model after accepting that local data will be erased.
You should see: The phone boots to initial setup.
Complete Google and Samsung verification
Sign in with the Google account and Samsung account previously used on the device when prompted.
You should see: FRP and reactivation locks clear.
Set a new screen lock
After setup, create a new PIN or password and rewrite it somewhere safe offline.
You should see: You can lock and unlock the phone normally again.

Extra tips
What to look for: Whether Find My Mobile was on, and whether the lock is a PIN, pattern, or biometric screen.
Before you change anything: Attempt Find My Mobile from another device before resetting. Back up nothing is possible while locked—accept data loss risk if resetting. Avoid unofficial unlock vendors.
