If you receive important texts on your Samsung Galaxy S III smartphone, you may want to save these messages for later. The Lock feature prevents you from accidentally deleting information that you want to keep. When you put a lock on a message, the Galaxy S III retains the text even if you delete the rest of the conversation that contains the important message.

Step 1

Tap the "Messaging" icon from the home screen.

Step 2

Choose the conversation that contains the message you want to lock, and then locate the specific message. Press and hold your finger on the message. A menu appears.

Step 3

Tap "Lock Message." A padlock icon appears to show that the message is locked.
