My Concord shuts down multiple times a day

May have a low memory issue going on.. Turn off any unnecessary features, and try pulling the battery out and putting it back in.. If that doesn't help, you my have to do a hard reset and restore it back to its factory condition... Here are the instructions to reset your phone: To perform a hard reset using hardware keys, follow these steps: Power off the device. Press and hold Volume Down key. Press and hold Power key until the Android and Triangle logo appears on screen. Let go of buttons once the logo appears. Press the device Home key. When the Factory Data Reset option appears, use the Volume keys to scroll to and select it with the Menu key. When Wipe data? appears, use the Volume keys to highlight Yes, and select it with the Menu key. Once Data Wipe Complete appears, use the Volume keys to highlight Reboot System Now and select it with the Menu key. Hope this helps...
