If Your Phone Doesn't Respond - Nokia lumia 830 User Manual

If your phone doesn't respond

If your phone stops working or responding in the way you're used to, you can quickly restart it to get
back on track.
Try the following:
• Press and hold the power key for about 10 seconds. The phone restarts.
If your phone freezes frequently, 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. Swipe down from the top of the screen, and tap
Reset your phone.
If your issue remains unsolved, contact your network service provider or the manufacturer 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.
