What is the master code for Samsung pattern unlock? I was locked out of my device because I recently set a more complicated pattern but forgot some of the characters I added. Thus, I wonder if a master code is available and if I can use it to unlock my Samsung phone. If so, can anybody please tell it to me? It would also help significantly help if you provide the process.

Master code, as you may expect, is a group of numeric values that allows users to bypass a device's lock screen. So, if your Samsung phone or tablet is locked and you can't provide the pattern, like the case above, it's unsurprising that you'd like to rely on a master code. Besides, it is also known not to compromise the device's data, letting you keep your phone from a reset.

Part 1. How to Use Samsung Pattern Unlock Master Code

Multiple master codes are available for Samsung phones, including 2767*2878#, 2767*3855#, and ##7780##. You must only apply them while performing the correct unlocking process, and your Samsung device’s pattern will quickly unlock. It is also free, so you won’t have to pay any fine or service to make the master code work. It is only essential that you accurately follow each step to prevent having troubles later. Meanwhile, using a master code to unlock a device doesn’t demand installation since the process will be on your Samsung phone or tablet’s dial pad. Thus, you don’t have to face technical steps since the dial pad is available even if the phone is locked.

Act according to the appropriate directions below to use the Samsung pattern unlock master code for unlocking your device:

Step 1First, take your SIM card off the Samsung device. Next, power it on, then proceed to the lock screen’s Emergency Call option. Your Phone app’s dial pad will then materialize.

Step 2Enter the code 2767*2878# and tick the Call button or symbol to process the master code. If it does not work, try 2767*3855# or ##7780## instead until your Samsung unlocks.

Although this method offers convenient navigation, you must still not be complacent, as the unlocking process through the master code is sensitive. Making even just a simple mistake could risk all your Samsung device’s content, as it has a high probability of a factory reset. Also, it could lead to a more complex lock, which might cause you not to re-access the device.
