How do I Delete the Call Logs or Call History on my Samsung SCH-r270?
Follow the instructions below to delete call logs.
You can delete your mobile device's call logs by pressing the key to open the recent calls list, and then pressing the right soft key for Options > Erase All. Select Yes on the confirmation screen. Erasing the recent calls list will not erase any of your contacts. Once you erase the recent calls list, you cannot recover any numbers not saved as contacts on your device.
