If you experience a "crash" of your device, in which it freezes up, try one of the following:

• Turn the device off by holding the power button down for at least three seconds. Then press the power button again to power on.
• Perform a soft reset (restarts device without shutting off its power) by pressing the following keys simultaneously: @ + 1 + 0.

If your device is still frozen, then call your operator's Customer Care number for assistance. All your data (messages, contact information, photos, settings) are saved on the servers, so even if your device crashes, your data is safe. Data restoration occurs automatically through a wireless air synchronization process.
