How to delete multiple text messages on a Samsung Intensity
On many mobile phones, you only have two options for deleting text messages: deleting one message at a time, or deleting a whole folder at a time. However, the Samsung Intensity (among other phones) gives you the option to delete multiple text messages at once without deleting an entire folder. You just have to know how to do it.
Go into the Messaging menu, either by pressing the upper left option button or by going into the main menu and selecting Messaging (option #2). Select your inbox, then press the upper right option button (Options). Select #9, Msgs View by Contact. The text messages in your inbox are now grouped according to who sent them.
From this view, you can delete multiple text messages at once. Press the upper right option button again and select choice #2, Erase Multiple. Now as your messages are displayed, there is an empty box next to each one. Scroll down through the list and select the messages you want to delete by pressing the center of the directional pad. A check will appear next to that message. To uncheck a message, repeat the same process.
The only messages you won't be able to delete are messages that you've previously marked as locked. If you want to delete a locked message, you'll have to unlock it first, then delete it.
Once you've put a check next to all of the messages that you want to delete, click the upper left option button (Done) and you'll see a confirmation message. Choose whether you want to delete all of the checked messages or only the unread ones, and then click the directional button (OK). The messages you selected will be deleted.
To resume having your messages displayed in chronological order, click the upper right option button and choose option #4, Msgs View by Time.
