In case of forgetting the lock code, a user can regain access to his Samsung Galaxy smartphone by signing in with his Gmail account and resetting the code. If he doesn’t have a Gmail account, he can initiate a hard reset and restore the smartphone to the default factory settings.
To regain access by using the Gmail account option, a user has to perform several incorrect attempts to input the code or draw a lock pattern. Once able to do so, he should input his username and password to log in to his Gmail account and then select an option to input a new security code or draw a new pattern.
To perform a hard reset, a user has to turn off the device. If he’s locked out of doing that, he can manually remove the battery from the smartphone. After that, he holds the Power, Volume Up and Home keys at the same time and releases the Power key once the system recovery screen appears. By using the Volume Down key, he selects the Wipe Data or Factory Reset option and presses the Power key to confirm the selection. The downside of the hard reset option is that it erases all personal data, although the process spares the information stored on a microSD card.
