5.9 What do I do if I hear static or sounds like "zzzzz" from
electrical interference when I make calls?
1. When the problem appears, if the sounds are choppy and interrupted, it is probably
electrical interference. Solve this in the following ways:
− For network problems, this relates to the strength or weakness of your mobile
network signal. Try moving to a location with a stronger signal and making a call.
− First, turn off the 4G network switch and try again to see if there is any improvement.
If there is improvement, this may indicate that the present 4G network is a newly
established network and is still in a state of instability.
2. When the problem appears, if there is a loud "zzzz" sound in the receiver, then the
problem doesn't relate to the network environment. It may be caused by the following
reasons:
− Some people's voices are comparatively loud and some people's ears are especially
sensitive to loud frequencies. When calling this sort of person, some people may hear
a slight "zzzz". This sound will be even more apparent to people whose ears are
comparatively sensitive.
− If you feel uncomfortable when listening, please lower the volume to a suitable level,
like volume level 1-2. This may completely resolve the problem.
− When you lower the volume, if the volume is too low, try adjusting the position of the
receiver to your ear so it is aligned with your ear.
− If you need to use your phone when spending long periods of time in locations where
the volume is loud (for example in noisy environments), try using a headset or
Bluetooth headset to make calls.
5.10 What do I do if, in the middle of a call, the call is
dropped and my phone enters airplane mode?
Presently, airplane mode may be activated in 2 main ways:
1. Activated through the shortcut in the status bar.
2. Activated through the menu which appears after you press and hold the power button.
It may be that some users hold their phones in a particular way which keeps the proximity
sensor from touching their ear so that when they make calls the screen doesn't turn off. This
may send false signals to the airplane mode switch on the status bar. Try adjusting the position
of the airplane mode among the status bar switches. For example, move it to the last switch in
the list. To move it, touch the last icon in the status bar switch screen to access the interface to
customize shortcut switches.
5.11 What do I do if I can't receive calls because the other
party hears that my phone is currently in a call or busy?
This is normally due to network anomalies and has nothing to do with the phone. If this
happens frequently, please contact your carrier for advice.
