Samsung One UI 9 Introduces Stricter Lock Screen Security: 13 Wrong Password Attempts Will Trigger a Factory Reset

Samsung is strengthening Galaxy device security with One UI 9, introducing a new lock screen protection policy designed to make brute-force attacks significantly more difficult. Under the updated system, entering the wrong PIN, password, or unlock pattern 13 consecutive times will permanently lock the device, requiring a factory reset before it can be used again.

The new security measure is part of Samsung's effort to better protect user data from unauthorized access. Instead of allowing unlimited password guesses, One UI 9 gradually increases the waiting period after repeated failed unlock attempts, making automated password attacks much harder.

One UI 9 Failed Unlock Attempt Limits

Samsung says the gradual lockout system helps stop attackers who repeatedly try different PIN or password combinations to gain access to a stolen device.

Biometric Users Still Need to Remember Their Password

Even if you primarily unlock your Galaxy phone using Fingerprint or Face Unlock, Samsung advises remembering your backup PIN, password, or pattern.

That's because Android requires users to enter their primary lock screen credential periodically—such as after restarting the device or approximately every 72 hours—before biometric authentication becomes available again. Forgetting that credential could eventually leave a factory reset as the only recovery option.

Remaining Unlock Attempts Will Be Displayed

To reduce accidental lockouts, One UI 9 will show users how many unlock attempts remain once they reach the warning threshold.

Samsung also notes that repeatedly entering the same incorrect PIN or password will not be counted as multiple failed attempts, helping prevent users from being penalized for repeatedly making the same mistake.

Which Devices Will Receive This Feature?

At launch, the stricter security policy applies only to Galaxy devices that ship with One UI 9 pre-installed, including:

1. Samsung Galaxy Z Fold 8
2. Samsung Galaxy Z Fold 8 Ultra
3. Samsung Galaxy Z Flip 8

Current testing indicates that Galaxy devices upgraded to One UI 9, such as the Galaxy S26 beta, do not currently include this new 13-attempt lockout policy. Samsung has not confirmed whether it will expand the feature to older Galaxy models in future updates.

Why Samsung Is Making This Change

Modern smartphones contain sensitive information such as banking apps, passwords, personal photos, documents, and digital identities. Samsung's latest policy aims to make it much more difficult for thieves or attackers to gain access by repeatedly guessing a user's lock screen credentials.

The update aligns with the industry's broader focus on improving mobile security and reducing the risk of unauthorized access to personal data.

DeviceDecode's Take

Samsung's new policy offers stronger protection against brute-force attacks, but it also raises the stakes for users who rely only on fingerprint or face unlock and rarely enter their backup password. If your Galaxy device receives this feature in the future, make sure you remember your lock screen credentials and keep regular backups of your important data.

Frequently Asked Questions

Will my Galaxy phone be erased after 13 wrong password attempts?

Only devices that launch with One UI 9 and support the new security policy will permanently lock after the 13th incorrect attempt, requiring a factory reset.

Does fingerprint unlock bypass this security feature?

No. Android periodically requires users to enter their PIN, password, or pattern even if fingerprint or face recognition is enabled.

Will older Galaxy phones receive this feature?

Samsung has not confirmed whether the new lock screen policy will be expanded to existing Galaxy devices through future One UI 9 updates.

Can I see how many attempts I have left?

Yes. One UI 9 displays the remaining unlock attempts once you reach the warning threshold.
