Precautions
Precautions
•
The terminal is a SIM lock free phone that
supports 5G, LTE, W-CDMA, GSM/GPRS and
wireless LAN systems.
•
Because the terminal uses radio frequencies, it
is not available inside a tunnel, underground,
building or other locations where radio waves
do not reach, in a place with weak radio
waves, or out of 5G service area or LTE service
area. Also, it may not be available on the
upper floors of high-rise apartments or
buildings, even if there are no obstructions
around you. Note that calls may be
disconnected even when you stay without
moving in areas with strong radio wave
condition indicated with the 4-signal icon.
•
Because the terminal uses radio waves to
communicate, it is possible that a third party
may attempt to tap your calls. However, the
LTE, W-CDMA, GSM/GPRS system
automatically scrambles all calls through a
private call feature. Therefore, even if the third
party successfully intercepts your call, they
will only hear noise.
•
The terminal operates on radio frequencies by
converting voice into digital signals. If a caller
moves into an area of poor radio wave condition,
the digital signal may not be restored accurately,
and the voice received in the call may differ
slightly from the actual voice.
•
For using a nano SIM card and eSIM at the
same time, available services, functions, etc.
may be restricted. DOCOMO is not liable to
any failures or malfunctions.
•
The terminal supports the function which
allows "User" or "Guest" to use the terminal.
Therefore some services or applications
recognize them as the same user even after
the user is switched. DOCOMO shall have no
liabilities for any damage or troubles of
customer or a third party resulting from using
the function (P.225).
•
Note down the data saved to the terminal in a
separate note on a regular basis or save to an
external recording medium such as a microSD
card or PC. Note that DOCOMO assumes no
responsibility for any loss of saved data
resulting from malfunction, repair, changing
of the model or other handling of the
terminal.
About using the terminal

5
Precautions
•
Verify providers and operating conditions of
applications, websites, etc. well before using
them. Some user-installed applications or
accessed websites may disrupt the stability of
the terminal performance, or unexpectedly
transmit information via the Internet causing
improper use of your location information as
well as personal information.
•
The terminal automatically performs
communication for synchronizing data,
checking the latest software version, and
maintaining a connection with the server, and
for other purposes. If you transmit a large
amount of data, such as when downloading
applications or watching video, a packet
communication charge becomes high.
Subscription to Packet Pack/packet flat-rate
service is highly recommended.
•
In the initial setting, the applications provided
by DOCOMO may be installed automatically.
And that incurs the packet communication
charge if you use mobile network. Such
applications will be selected automatically by
predicting your needs based on the
information you have offered to DOCOMO
upon your consent beforehand or your other
information we hold. We manage how to
handle your information in an appropriate
manner defined by our privacy policy.
•
Depending on the applications or services
you are using, the packet communication
charge may be incurred even when
communicating via Wi-Fi
®
.
•
If available memory in the microSD card or
the internal storage is low, running
applications may not operate correctly. In that
case, delete the saved data.
•
Set a password etc. for the screen lock to
ensure the security of the terminal in case of
loss (P.213).
•
If your terminal is lost, change your each
account password to invalidate
authentication using a PC to prevent other
persons from using Google services such as
Gmail or Google Play, or SNS, etc.
•
For using services and applications provided
by the third party's including applications
provided by Google LLC, confirm the terms
and conditions, etc. specified by Google or
the providers. DOCOMO assumes no
responsibility for any malfunctions resulting
from the services and applications.
•
When a license agreement screen etc.
appears, follow the onscreen instructions.
•
Applications and service contents are subject
to change without prior notice.
•
For details on usage charge, refer to NTT
DOCOMO website.

Precautions
•
Display is manufactured by taking advantage
of highly advanced technology but some
dots may be always or never lit. Note that, this
shows characteristics of the display and not
defects in the terminals.
•
The terminal has an organic EL display.
Although an afterimage may occur when the
same image has been displayed for a long
time, it is not a malfunction. To prevent the
display from having afterimages, do not
display the same image for a long time.
•
The screen may become partially dark or the
colors may be changed if you set the display
brightness to brighter than necessary or use
the terminal extremely for a long time. Also,
unevenness of colors or brightness, or
changes of colors may be found depending
on direction you are looking. That is because
of the structure of organic EL display, not a
malfunction.
•
DOCOMO is not liable to any failures or
malfunctions for commercially available
optional equipment.
