Unlock Samsung Z Flip/Fold Locked Screen Without Password

How to Unlock Samsung Z Flip/Fold Locked Screen Without Password?

Samsung’s Z Flip and Z Fold series combine cutting-edge display engineering with high-end security features. Yet these same protections can become a barrier when you suddenly forget your PIN, pattern, or password—or when your device locks you out after multiple failed attempts. Because these foldable models rely heavily on biometric pairing, dual-screen gestures, and encrypted partitions, bypassing a locked screen isn’t as straightforward as with older Samsung devices. Many users hesitate to reset the phone because they fear data loss or triggering security locks such as Samsung’s Factory Reset Protection (FRP).

Fortunately, several effective and safe solutions exist. Some methods rely on built-in Samsung services, while others use specialized tools designed for unlocking without password input. In this guide, we’ll break down practical, technical, and data-preserving ways to regain access to your Samsung Z Flip or Z Fold—without resorting to factory reset unless absolutely necessary. Each method aims to help you act confidently, avoid data damage, and understand why these techniques work.

Solution 1: Unlock Samsung Z Flip/Fold Using Samsung Unlocker (Recommended)

This method is ideal when you want to unlock your Samsung Z Flip or Fold without data loss, without knowing the password, and without dealing with complicated command lines. Samsung Unlocker from iDatApp bypasses lock screens built with Samsung’s Knox-based encryption by utilizing device-specific protocols that communicate with the phone in recovery or download mode. Unlike generic tools, it is optimized for Samsung foldable devices, which require special handling due to their split-display framework and persistent biometric partition.

This solution is especially useful if your touchscreen is unresponsive, your biometrics fail, or the phone is stuck on the lock interface.

Steps to unlock Samsung Z Fold/Flip Series Phone:

1.Install Samsung Unlocker

Download and run the software on your Windows or Mac computer.

2.Connect Your Samsung Z Flip/Fold

3.Choose “Remove Screen Password” Mode and select your phone brand model.

The program loads the correct device profile and firmware package required for secure unlocking.

4.Start Unlocking Process

Follow on-screen prompts, click Remove Now. The software communicates with your device’s secure boot environment to remove the lock screen credentials.

5.Reboot and Access Your Phone

Once finished, your device restarts without requiring a PIN, pattern, or password.

Tips & Warnings:

• Ensure at least 30% battery to avoid sudden shutdown during unlocking.
• Do not disconnect the USB cable when device information is updating.
• Works for Samsung Z Flip 3/4/5 and Z Fold 3/4/5, including the newest Android versions.

Solution 2: Unlock Samsung Z Flip/Fold Through Samsung Find My Mobile

Samsung’s Find My Mobile service is one of the safest official solutions for password-less unlocking. When enabled before the lockout, it uses remote authentication to verify ownership and remove the lock screen directly from Samsung’s server side. This method works particularly well for users who rely on Samsung Cloud and have a stable network connection.

The main advantage is that it does not erase data. However, it only works if the phone has an active internet connection and the “Remote Unlock” feature was turned on beforehand.

Steps:

1.Go to the official Find My Mobile website on a computer or another phone.

2.Log in using the same Samsung account associated with your Z Flip/Fold.

3.Once the device appears on the left panel, select “Unlock”.

4.Enter your Samsung account password to confirm identity.

5.The device receives a remote command and removes the lock instantly.

Tips & Warnings:

• If your device is offline, the unlock command will queue until the phone reconnects to the internet.
• FRP (Factory Reset Protection) remains intact—this method only unlocks the screen.
• Does not work if Samsung account sync was disabled prior to being locked out.

Solution 3: Unlock with Google Account/Smart Lock (If Previously Set Up)

Some Samsung Z Flip/Fold users rely on Google’s ecosystem rather than Samsung’s. If you previously enabled Smart Lock—trusted devices, trusted locations, or on-body detection—you may be able to unlock the device without entering a password. This method works because Smart Lock temporarily bypasses the lock screen when predefined safety conditions are met.

Though not widely understood, Smart Lock communicates with the Android Trust Agent system, verifying whether your device is in a secure environment. If you forgot your lock screen credentials but still have access to a trusted Bluetooth device (e.g., Galaxy Watch, car system), you may be able to unlock the phone seamlessly.

Steps:

1.Check for Bluetooth Pairing

Bring your Z Flip/Fold close to the trusted Bluetooth device that was previously linked.

2.Try to Wake and Swipe

If Smart Lock recognizes the trusted condition, the locked screen will automatically unlock with a simple swipe.

3.Use Google Account Recovery (Older Android Versions)

On devices running Android 11 or earlier, you may see a “Forgot Pattern?” option after several attempts. Enter your Google account to unlock.

4.Turn Off the Password Later

Go to Settings → Lock Screen → Remove or change screen lock method.

Tips & Warnings:

• Smart Lock does not work if your phone was restarted recently; Android requires password entry after reboot for encryption security.
• Only applicable if these features were set up before getting locked out.
• Not guaranteed for every foldable model depending on firmware.

Solution 4: Unlock Samsung Z Flip/Fold Using ADB Commands (Advanced Users)

For users with ADB (Android Debug Bridge) enabled before lockout, this method can remove specific lock screen credential files. The logic behind this approach is that Android stores lock screen hashes in encrypted system partitions. If USB debugging was previously authorized, ADB can delete these files, prompting the system to create a new default lock state after reboot.

This is a highly technical method and works best for advanced users familiar with command-line tools.

Steps:

1.Connect your Z Flip/Fold to your computer via USB.

2.Open your command prompt or terminal and type:

• adb devices

Ensure the device is recognized.

3.Remove lock screen database:

• adb shell rm /data/system/gesture.key
• adb shell rm /data/system/password.key
• adb shell rm /data/system/locksettings.db

4.Reboot your device:

• adb reboot

5.After rebooting, the lock screen will either disappear or allow you to set a new credential.

Tips & Warnings:

• Does not work if USB debugging wasn’t enabled beforehand.
• Highly sensitive—deleting the wrong system files may cause boot issues.
• Not recommended for beginners or users who rely on their device for daily work.
