Smartphones play an important role in our daily life. Nowadays, almost all smartphones have a lock screen function, especially the popular Samsung phones. To protect your privacy and data, setting a customized pattern lock or password lock for your device is one of the common security measures.
However, in a fast-paced life, there is a chance that you might forget your unlock code. If you forget the pattern lock, how do you unlock it? Is there a universal Samsung pattern unlock master code? In this article, we will cover multiple ways to unlock a locked Samsung phone without password. Keep reading.
Master codes are usually associated with older mobile technologies and are also known as SPC (Service Programming Codes) which can be used to unlock the basic functions of the device or reset the device. Some of the popular Samsung unlock master codes on the internet are:
• 2767*2878#
• 2767*3855#
• ##7780##
While there exists a universal unlock master code, these combinations of numbers are only valid for specific older devices. For today's smartphones, especially the newer Samsung models, there is no longer any support for a master code to unlock the phone. So when you forget your Samsung phone pattern lock password, you should use another trusted solution to unlock it in order to access the device again.
Assuming that your locked Samsung phone is running a lower version of the system (typically Android 4.4 and below), you can follow these steps to try to unlock your Samsung phone with the pattern unlock master code.
Note: All data and settings on your phone will most likely be erased during the unlocking process and the Master Password does not secure the data on your device.
Step 1: Turn off your Samsung phone and then remove its SIM card.
Step 2: Reboot your phone, then tap the phone or emergency call icon on the screen.
Step 3: Enter the Samsung unlock master code listed above one by one and then wait for device verification. If the verification passes, your phone will be unlocked, otherwise you need to move on to another unlocking solution.
If your Samsung phone has advanced security protocols, then a simple universal unlock code will most likely not unlock it. You can try other Samsung unlock master password alternative solutions like iSunshare Android Password Genius. It is a universal Android unlocker designed to bypass all types of locks on Android phones, including Pattern, Pin, and Numeric passwords.
This software also functions as a Samsung FRP bypass tool. After performing a factory reset on your phone, you can use it to remove the FRP lock on your Samsung device without entering your Google account, if necessary.
Step 1: Go to visit the iSunshare Android Password Genius webpage to download and install it on your PC.
Step 2: Run the software, click on "install" to download a specific driver for detecting your Samsung phone. Then select "Unlock Screen Lock" option.
Step 3: Connect your device to the PC and select its brand.
Follow and complete the on-screen instructions and click "Next", the software will start to remove Samsung pattern lock immediately.
Step 4: Wait patiently for the removal process to complete, keep your Samsung phone connected to the computer at all times until the "Remove screen lock successfully" message appears on the screen.
Samsung's "SmartThings Find" offers a reliable way to erase your device without having to enter Recovery Mode, which allows you wipe all the data and settings of your Samsung phone, including its pattern lock, and the service is free. However, your device needs to meet the following requirements:
1. Your phone is logged into a Samsung account.
2. The device's location services are turned on and connected to the Internet.
3. You will be asked to provide the password of your Samsung account during the unlocking process.
Step 1: Go to the SmartThings Find website and enter the associated Samsung account and password to log in.
Step 2: Select your locked Samsung phone from the device list and click on the "Erase Data" option in the function bar.
Step 3: You may be asked to enter a two-step verification code. To continue erasing Samsung data, you will also need to enter your Samsung account password to verify that it's you.
Finally, read the important warning message in the pop-up window and click "Erase", your phone will be factory data reset immediately, just wait for the process to finish.
Before "Find My Device" is integrated with "SmartThings Find", Samsung users could use the "Unlock" option to unlock the Samsung phone pattern lock without a factory reset.
However, now that the "Unlock" option has been removed, it's unclear if it will be restored. If you have important unbacked files on your Samsung phone, please consult Samsung technical service team for assistance.
In conclusion, although there are some master codes to unlock Samsung phone password, they are only available for a small percentage of devices that do not have updated security protocols. If your device is running a newer system, it is recommended to choose a more secure and reliable unlocking method such as Android Password Genius and "SmartThings Find".
