If your phone doesn’t respond
Try the following:
• Press and hold the volume down key and power key at the same time for about 10 seconds. The 
phone restarts.
If your phone frequently doesn’t respond, update your phone software, or reset your phone. 
Resetting restores the factory settings, and erases all your personal content, including apps you've 
purchased and downloaded. On the start screen, swipe down from the top of the screen, and tap ALL 
SETTINGS > about > reset your phone.
If your issue remains unsolved, contact your network service provider or Microsoft Mobile for repair 
options. Before sending your phone for repair, always back up your data, as all personal data in your 
phone may be deleted.
Tip: If you need to identify your phone, to view the unique IMEI number of the phone, dial 
*#06#. You can also find the IMEI number in the phone body. For details, see the product and 
safety information section in the online user guide.
