How to unlock Samsung Galaxy A71 if you forgot your password or pattern

Forgotten password on Samsung Galaxy A71 can turn into a real headache, especially if important data, photos or work documents are stored on the phone. Unlike iPhone, where unlocking without a password often requires contacting a service center, Android offers several official and unofficial methods to restore access. However, not all methods are equally safe: some lead to total data loss, others work only under certain conditions (for example, if USB debugging is enabled or the phone is linked to a Samsung account).

In this article we will analyze 5 working methods of unlocking Galaxy A71 —from the simplest (via Find My Mobile) to radical (hard reset via Recovery Mode). We will pay special attention to the nuances that are often missed in standard instructions: what to do if you don’t remember your Google login, how to bypass the password request after a reset, and why some methods stopped working after the Android 12 update. You will also find unique information about Samsung's hidden function "Emergency Mode"which can help in a critical situation.

1. Unlocking via Samsung Find My Mobile (the safest way)

If your Galaxy A71 function is enabled Find My Mobile (analogous to "Find My Device" from Google), you can unlock your phone remotely - without losing data. This method works even if you do not remember the password for your Google account, but remember the data from your Samsung account.

🔹 Conditions for this method:

• 📱 The phone is connected to a mobile network or Wi-Fi.
• 🔋 The battery charge level is above 10% (otherwise the device may turn off during process).
• 🔑 The function Find My Mobile was activated in the settings Samsung before blocking.
• 🌐 You have access to a computer or another phone with the Internet.

📌 Step-by-step guide:

1. Go to the site Find My Mobile from any device.
2. Login using the same Samsung account that is linked to the blocked one Galaxy A71.
3. In the left menu, select the item Unblock (Unlock).
4. Confirm the action with a password from your Samsung account.
5. Wait for synchronization - the phone will unlock automatically (a reboot may be required).

⚠️ Attention: If after unlocking the phone requires you to enter the old password, try rebooting it. If this does not help, you will have to use another method (for example, resetting via Recovery).

Make sure that mobile data is turned on on your phone or it is connected to Wi-Fi|

Check the battery charge (at least 10%)|

2. Unlocking via Google account (only for Android 9 and below)

This method worked for Galaxy A71 with factory firmware based on Android 9 or 10, but after updating to Android 11/12 Samsung removed the ability to reset the password via Google. However, if your phone has not been updated for a long time, it’s worth a try.

🔹 How it works:

After 5 unsuccessful attempts to enter the password, the system offers an option Forgot your password?, which redirects to the page for entering data from your Google account. Successful authorization allows you to create a new password.

📌 Instructions:

1. Enter any password on the lock screen 5 times in a row.
2. A message will appear Forgot your pattern? or Forgot your password? —click on it.
3. Enter the email and password from the Google account that was linked to the phone.
4. Follow the instructions to create a new password.

⚠️ Attention: On Galaxy A71 with Android 11+ this method does not work - Samsung has removed the "Forgot your password?" option. from the lock interface. If you have a new version of the OS, proceed to the next method.

Why did Samsung remove unlocking via Google?

Since 2020, Google has tightened Android security requirements, obliging manufacturers to remove the password reset feature through an account. This is due to the risk of abuse: attackers could reset the password on a stolen phone by knowing the owner’s email. Samsung complied with the requirement, but left an alternative - unlocking through its own Find My Mobile service.

3. Password reset via ADB (only if USB debugging is enabled)

Method for experienced users who have previously activated Developer mode and enabled USB debugging. If these settings were enabled before the lock, you can delete the password file using the ADB command.

🔹 What you will need:

• 🖥️ Computer with installed Samsung drivers and tool ADB.
• 🔌 USB cable (preferably original).
• 🔧 Knowledge of the command line (or willingness to follow instructions).

📌 Step-by-step guide:

1. Connect Galaxy A71 to your computer via USB.
2. Open the command line (Windows) or terminal (macOS/Linux) in the folder with ADB.
3. Enter the command to check the connection:

   adb devices

   If the device is displayed in list, proceed further.

4. Delete the file with the password:

   adb shell rm /data/system/gesture.key

   or for the PIN code:

   adb shell rm /data/system/password.key

5. Reboot the phone:

   adb reboot

After the reboot, the lock screen should disappear. If not, try entering any password (sometimes the system resets the verification).

⚠️ Attention: This method does not work on Galaxy A71 with data encryption (enabled by default on Android 10+). If during boot the system asks for a password for decryption, ADB will not help, a flashing is needed.

4. Hard reset via Recovery Mode (loss of all data)

If other methods did not work, a radical option remains - reset to factory settings. This will delete all data from your phone, including photos, messages, and apps, but will restore access to your device. On Galaxy A71 this process takes 5-10 minutes.

🔹 When to use:

• 🔐 You do not remember the password and did not link the phone to Samsung/Google accounts.
• 📱 There is no important data on the phone (or it is synchronized with the cloud).
• 🔧 Other methods did not work or are not available.

📌 Reset instructions:

1. Turn off Galaxy A71 (press the power button + volume down for 10 seconds).
2. Press simultaneously: Power button + Volume up + Bixby (if available).

   Hold until the Samsung logo appears.

3. In the Recovery menu, select Wipe data/factory reset using the volume buttons and confirm with the power button.
4. Select Yes to confirm the reset.
5. Once completed, press Reboot system now.

The phone will reboot and offer to set it up as new. If after the reset you are prompted to enter the old password (FRP protection), use the method with Find My Mobile or contact the service center.
