For the initial unlocking of the Samsung Galaxy 3.6, look for an online unlock code. Select the device, and enter the international mobile equipment identity number of the respective phone.
Click on the generate button. It provides an unlock code, which should be entered into the device for unlocking.
Once in use, the device automatically locks when the screen times out, or the manual locking mechanism can be used. To unlock the device, press the power/lock key.
The locked screen then displays a message that says sweep glass to unlock. Touch and sweep across the screen either to the left or to the right as indicated. It is possible to select the type of screen unlock. The choices include unlocking using a password, a personal identification number or a pattern.
In case the password is forgotten, the only way to unlock the device is a hard reset. Start by holding down the power button to switch off the phone. Then, pressing the volume up button and the home button, hold the power button. When the phone is on, release the power button, but continue to hold down the other buttons until the recovery screen appears.
Select the volume up and volume down button to choose the factory reset, which resets the phone. The initial unlocking technique can then be used to unlock the phone.
