Phone Call; Notification Panel - Huawei P8 GRA-UL00 Faqs

P8 Smartphone FAQs
5.10 Why is my phone disconnected from the 4G network
when I make phone calls?
Currently, 4G networks support data services only and do not support voice services.
Therefore, when you make phone calls, your phone falls back from the 4G network to the 3G
or 2G network. If your phone falls back to the 2G network, you cannot use the data services.
5.11 Why can't I make phone calls or calls drop even when
the signal is strong?
Calls are not only affected by signal strength but also signal quality (such as the degree of
interference). Network resources can also affect calls. Generally, occasional call failures or
call drops are caused by bad network conditions.
5.12 What can I do if a message indicating that a voice
mailbox number is missing is displayed when I make a

phone call?

You can enter the voice mailbox number in Settings > Calls > Voice mailbox number. You
can get this number when you subscribe to the voice mailbox service in a service counter. If
you forget this number, you can call your carrier's service number (for example, 10086 for
China Mobile) and retrieve this number.
5.13 Why can't my dialer display phone numbers from
historical calls?
Your phone does not support such a function and the dialer can only display phone numbers
from the contacts.
5.14 Why can't I clear the notifications for new voice mails
by flicking down from the status bar to display the

notification panel?

Press and hold the notification, drag it to the left or right, and touch OK in the displayed
dialog box. Even though a message is displayed indicating that exceptions may occur in the
application if you forcibly clear this notification, your phone's functions will not be affected.
After you clear this notification, it will not be displayed again. A new notification will be
displayed only if you receive a new voice mail.
