2. Using ADB (for users with debugging enabled)

The method is suitable if on the phone was previously enabled USB debugging (usually activated by developers or when connected to a PC to transfer files). Check if this method is right for you:

  • 🔧 The phone has ever connected to this PC via ADB (there was confirmation of a trusted device).
  • 🔧 On The computer has drivers installed Samsung USB Driver and ADB (included in Android SDK Platform Tools).
  • 🔧 Android version not newer than 11 (on Android 12+ requires physical confirmation of unlocking).

Instructions for Windows:

  1. Download Platform Tools and unzip to a folder C:\adb.
  2. Connect the phone to the PC via the original cable.
  3. Open Command line as administrator and go to the folder with ADB: 
    cd C:\adb
  4. Run the commands one by one: 
    adb devices

    (the serial number of the phone should appear)

    adb shell rm /data/system/gesture.key
    adb reboot

After the reboot, instead of the pattern, a field for entering a PIN code will appear (by default - 0000, 1234 or the last used PIN. If it doesn’t work, try an alternative one). command:

adb shell rm /data/system/locksettings.db
⚠️ Attention: On Samsung Galaxy s One UI 4.0+ (Android 12+) this method may not work due to enhanced protection KnoxIn this case, try the method with Safe Mode (section). 4).

1. Reconnect the cable to another USB port (preferably 3.0).

2. Install drivers manually via Device Manager (select "Samsung ADB Interface").

3. Use another PC where the phone was connected previously.-->

3. Unlocking via Google account (for Android 4.4–9.0)

This method worked on older versions of Android, but Samsung it is gradually being abandoned. However, on some models (Galaxy J, Galaxy A 2016–2018) it can be used:

  • 📱 Enter the wrong pattern 5 times in a row.
  • 📱 A button will appear Forgot your pattern key? (on some firmware - Restore access).
  • 📱 Enter the email and password for Google accountlinked to your phone.

If the button does not appear, it means:

  • ❌ The phone is installed One UI 2.0+ (Android 10+), where this function was removed.
  • ❌ The device was reset to factory settings earlier (the link to the account is reset).
  • ❌ The phone was released after 2019 (on new models it is used only Find My Mobile).

Alternative for new models: If the phone is connected to Wi-Fi, try calling Google Assistant voice (say "Okay, Google"). Sometimes you can open the settings through it and disable the lock.

Why did Samsung remove unlocking via Google?

Since 2019, the company has switched to its own security system Knox, which blocks workarounds. This is due to requirements. Android Enterprise and protection of corporate data. Now unlocking is possible only through official services (Find My Mobile or reset).

4. Booting into Safe Mode allows you to temporarily disable third-party applications, including third-party screen lockers (for example,

Safe Mode allows you to temporarily disable third-party applications, including screen lockers from third-party developers (for example, AppLock or Norton App Lock). On a standard graphic key Samsung this method works in 30% of cases.

How to boot into Safe Mode:

  1. Turn off the phone (press Power + Volume Down for 10 seconds).
  2. When the logo appears Samsung press and hold Volume down and hold until the inscription appears Safe Mode in the lower left corner.
  3. Enter any pattern - sometimes the system skips it in safe mode.

If unlocking was successful:

  • 🔓 Remove third-party screen lockers in Settings → Applications.
  • 🔓 Reboot your phone in normal mode.
  • 🔓 Set a new pattern in Settings → Biometrics and security → Screen lock.

What to do if Safe Mode did not help? Try the combination c ADB (section 2) or contact the service center Samsung —they have internal tools for unlocking without data loss (for a fee, ~1500–3000 ₽).

💡

Safe Mode is the only one a way to bypass blocking from third-party applications. On a standard Samsung graphic key, it works less often, but does not require a connection to a PC or the Internet.

5. Resetting the pattern key via Samsung Smart Switch (for backups)

If you regularly create backups via Samsung Smart Switch, you can try restoring the phone to its state before blocking. This method is suitable if:

  • 💾 There is a fresh backup copy (made no later than 7 days before blocking).
  • 💾 The phone is recognized by the computer in mode Download Mode.
  • 💾 The app is installed on the PC Smart Switch (version 4.2.20114 or newer).

Step-by-step algorithm:

  1. Connect the phone to the PC via USB.
  2. Hold Power + Volume Down + Bixby (on new models - Power + Volume Up) to enter Download Mode.
  3. B Smart Switch select Restore and specify the latest backup.
  4. Wait for completion (the process will take 20-40 minutes).

Important: this method does not guarantee 100% data safety. Some files (for example, messages in instant messengers or application settings) may not be restored. Before the procedure, check exactly what data is included in the backup:

Data type Stored in Smart Switch? Notes
Contact ✅ Yes If synchronized with a Samsung/Google account
Photo/video ✅ Yes Only if the copy was created with the "Multimedia" checkbox
Messages (SMS) ✅ Yes Messages from WhatsApp/Telegram are not restored
Applications ⚠️ Partially Only icons on the main screen are restored
System Settings ✅ Yes Including wallpaper, sounds, network settings

6. Contacting Samsung service center: official methods

If none of the above methods work, all you have to do is contact your authorized service center Samsung. The company has internal tools for unlocking without data loss, but with some caveats:

  • 🔧 Proof of ownership will be required (receipts, box, IMEI).
  • 🔧 Service cost: from 1500 to 5000 ₽ depending on the model.
  • 🔧 On phones with Knox eFuse (all flagships after 2018) only a full reset can work..

FAQ: Frequently asked questions about unlocking Samsung

❓ Is it possible to unlock the phone without losing data if USB debugging is not enabled?

Yes, but only through Find My Mobile (if the account Samsung linked) or in service center. Other methods (ADB, Smart Switch) require preliminary setup of debugging or a backup.

❓ Why, after resetting via ADB, does the phone ask for a PIN and not a pattern?

Command rm /data/system/gesture.key deletes the file with the pattern, but the system switches to the backup unlocking method - PIN. If you have not installed it, try standard combinations: 0000, 1111, 1234 or the last used PIN from the SIM card.

❓ Does unlocking through a Google account work on the Samsung Galaxy S22?

No. Starting from One UI 4.0 (Android 12) Samsung has completely removed this feature. The only working methods are Find My Mobile or a service center.

❓ Is it possible to unlock the phone if it is turned off and does not turn on?

If the phone is low or does not respond to the power button, charge it first (keep it on charge for 30-60 minutes). If the screen remains black, the problem may be a hardware failure (for example, a fried motherboard). In this case, unlocking using software methods is impossible - repair is required.

❓ What to do if photos are missing after unlocking?

Check the folder DCIM/.thumbnails - sometimes the thumbnails are saved. Also try data recovery apps (DiskDigger, EaseUS MobiSaver), but the chances are low if the phone has been rebooted. In the future, set up automatic backup in Google Photos or Samsung Cloud.
