With the quick calling function enabled, when the screen is off, you can press and hold the
volume down button and speak the contact name after hearing the prompt tone. Then, the
phone can quickly make a call.
5.49 When my dual-card phone displays emergency calls,
why can I make calls?
Your phone supports dual cards. An exclamation mark indicates that the corresponding SIM
card is not inserted to your phone. In such a case, you can only make emergency calls.
Emergency call displayed on your lock screen is an entrance to the dialer screen where you
can only make emergency calls.
5.50 Why is the incoming number displayed as unknown?
If you do not activate the caller ID display service, the incoming call numbers are displayed as
unknown. It is possible that the caller ID display service is deactivated by the service provider
when you replace a new 4G card. If such a problem occurs, you can call the customer service
center of the service provider to activate the caller ID display service.
5.51 Why is the screen still off after I move my phone
away from my ear?
Your phone has a proximity sensor that is installed near the receiver.
During a call, if you place the phone near your ear or use another object to block the upper
part of the screen, the phone automatically turns the screen off to avoid misoperation. When
the phone is moved away from the blocking object, the phone automatically turns the screen
on to facilitate your operations.
If the screen is still off after you move your phone away from your ear, press the power button
and make sure the upper part of the screen is not blocked by another object.
5.52 How do I delete call logs?
On the Dialer screen, touch the menu icon then Delete call log.

Do not block the area around the receiver with the phone cover or other objects. When you attach a
protective film to the screen, make sure it does not block the proximity sensor. It is recommended that you
use a protective film dedicated to your phone.
