How to unlock Samsung's old man's mobile phone if he forgets his password?

Samsung mobile phone password unlocking method;

1, turn it off first, because the phone can be turned off normally with or without a password. You can enter recovery after shutdown. How to enter recovery? It's very simple. At the same time, press and hold the power button+volume increase button, and at the same time press and hold the home button in the middle of Samsung mobile phone. It should be noted here that there are many models of Samsung mobile phones, and the steps for different models to enter recovery are different. You can check your Samsung mobile phone to enter recovery. Although different models of Samsung mobile phones enter the recovery in different ways, because they are the same brand of mobile phones, the methods are similar.

2. Now we are in recovery. Different models have different interfaces, but they are all similar. Now, you can move and select by increasing or decreasing the volume. Now we need to find this in this interface: Erase data/restore factory settings. If the phone is still turned on after the selection, you can find this "restart the system immediately" to confirm the selection. Generally speaking, after selecting this, the phone will automatically restart. After restarting, the factory settings are basically restored, so there is no password, and the password of Samsung mobile phone will be unlocked.
