Unlike iPhonewhere unlocking without a password often requires contacting a service center, Android offers several ways to solve the problem - from official manufacturer tools to technical workarounds. However, it is important to understand: not all methods are safe, and some can lead to data loss or even device breakdown.

This article covers current unlocking methods for 2026including legal options for owners (via Google Account, Find My Device) and technical tricks for advanced users (mode Fastboot, ADB, reset via Recovery). We will also look at why some popular tips on the Internet (like “call a locked phone”) do not work on modern versions Android 12-15, and what risks do “grey” unlocking services pose.

Before you begin, answer honestly: you are the legal owner of the device? Unlocking someone else's smartphone without the owner's consent may violate Article 272 of the Criminal Code of the Russian Federation (illegal access to computer information).

The most reliable method is to use Google Accountlinked to the device. However, with the release Android 5.0 Lollipop (and even more so in Android 12-15) the unlocking function through the account removed from the interface. However, it is saved in some firmware from manufacturers, for example, on Samsung or Xiaomi with proprietary shells One UI and MIUI respectively.

• 🔑 Find My Device —a service from Googlethat allows you to reset your password remotely. Works if Remote control and Geolocationare turned on on the phone, and you also have access to the Internet.
• 📧 Recovery via email —on some devices, after 5 incorrect entry attempts, the “Forgot your password?” button appears. with a prompt to enter your email address.
• 📞 Reset via SIM card is an outdated method that worked for Android 4.4 and below. Modern smartphones do not support it.

On devices Samsung s One UI (for example, Galaxy S23, A54) after several unsuccessful input attempts PIN code an option Unblock via Samsung Accountmay appear. To do this:

1. Enter the wrong PIN 5 times in a row.

If the device not connected to the network, the service will show its last known location, but you won’t be able to reset the password. In this case, try connecting the phone to the charger and waiting for Wi-Fi to appear - sometimes this will activate background processes.

What to do if Find My Device does not see the device?

If the phone is not displayed in the list, check:

- The account is correct (perhaps another Google profile was authorized on the device).

- Synchronization settings (on some firmware you need to manually enable the "Find Device" function).

However, this method requires preliminary preparation and does not work on all firmware.

Attention: with exit Android 11 and newer Google tightened the security policy, and many ADBcommands for unlocking stopped working. However, on some devices (especially with custom firmware) the method remains relevant.

Instructions:

1. Connect the phone to the computer via USB cable (original, not a cheap charger!).
2. Open Command line (Windows) or Terminal (macOS/Linux) in the folder with ADB (you can download from official website).
3. Check the device connection with the command:

   adb devices

   If the phone is displayed in the list, proceed further.

4. Delete the file from password (does not work on all devices!):

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

5. Unlocking via Fastboot (for devices with an unlocked bootloader)

Mode Fastboot allows you to flash the device at a low level, including deleting PIN code. However, this method is only suitable for smartphones with unlocked bootloader (bootloader). On most serial devices, the bootloader is locked, and unlocking it leads to full reset (and on some models, for example, Xiaomirequires waiting 7-15 days after linking the account).

If the bootloader is already unlocked (for example, on devices for developers or after rooting), follow the instructions:

1. Turn off the phone.
2. Hold the combination to enter Fastboot (usually Power + Volume down).
3. Connect the device to the PC and check its detection:

   fastboot devices

4. Delete files with passwords (similar to ADB, but through Fastboot):

   fastboot erase locksettings

   On some devices you may need:

   fastboot flash locksettings locksettings.img

   (where locksettings.img is an empty file that needs to be created in advance).
