About usage of the terminal
• The terminal supports LTE, W-CDMA, GSM/GPRS, and wireless LAN.
• Because your terminal uses wireless transmission, it may not function in
locations where it is difficult for radio waves to penetrate, such as tunnels,
underground passages and some buildings, in areas where radio waves are
weak, or out of LTE service area and FOMA service area. Even when you
are high up in a tall building or condominium and nothing blocks your view
outside, your terminal may not be able to receive or transmit signals. Also,
communication may be interrupted even when the signal meter on your
terminal.
• Because your terminal uses radio waves to communicate, it is possible that a
third party may attempt to tap your calls. However, LTE, W-CDMA, GSM/GPRS
system automatically applies a confidential communication function to all
calls, so even if a third party could somehow tap a call, they only hear noise.
• The terminal encodes voice communication as digital data. When you are
operating your terminal while moving to a location subject to weaker radio
wave conditions, the transmitted digital data may not be correctly decoded
and as a result the decoded voice may differ somewhat from the actual voice.
• The terminal supports FOMA Plus-Area and FOMA HIGH-SPEED Area.
• Keep the information that you registered in the terminal separately by noting
down periodically or saving to microSD card, PC etc. Note that DOCOMO
assumes no responsibility for any loss of saved contents of data resulting from
malfunction, repair, changing of the model or other handling of the terminal.
• Although the display is manufactured with extremely advanced technology,
some dots may not be lit or be always lit. It is characteristic of the display and
not malfunction. Please be forewarned.
• If the terminal internal storage or the microSD card does not have enough
memory, running applications may not work normally. In such case, delete
saved data.
• DOCOMO shall not be liable for commercially available optional equipment.
• As with PCs, some applications that you perform installation may give the
terminal instability of the operation, or may send your location information
or personal information registered to the terminal to outside via the Internet
and the information may be used improperly. Therefore, verify the supplier and
operating conditions of the applications before use them.
• Only the docomo nano UIM card is available for the terminal. If you have the
UIM card docomo mini UIM card or the FOMA card, exchange it for the docomo
nano UIM card at the docomo Shop.
• The terminal does not support accessing i-mode site (programs) and i-α ppli,
etc.
• The terminal automatically performs communications for some functions, for
example, to synchronize data, check the latest software, maintain connection
with the server, etc. Additionally, when you download applications or watch
video etc., a large amount of packet communication charges are executed.
Therefore, it is highly recommended to use packet pack or packet flat-rate
service.
• Depending on applications or services you use, a packet communication fee
may be charged even if you perform Wi-Fi communication.
• The terminal does not support Public mode (Driving mode).
• In the terminal, sounds (video sound, music shutter sound, etc.) other than
ringtone and each notification are not muted even when Silent mode (Vibrate,
Mute) is set.

From the Home screen, → "Settings" → "About device" → "Status" → Tap
"SIM card status".
• You can update software of the terminal to the latest one (P.147).
• In the terminal, functions may be added or operation steps may be changed
due to upgrading Operating System (OS). For latest information of additional
function or operation steps, refer to NTT DOCOMO website.
• When OS is upgraded, some applications used for former OS may not work or
unintended failure may occur.
• Applications or services are subject to change without prior notice.
• For services provided by Google, thoroughly read the Terms of use of Google
Inc. And for other web services, read each terms of use.
• If the terms of use appear, follow the instructions on the screen.

so that Google Services such as Gmail, Google Play, and service such as SNS,
etc. should not be used by others.
• The terminal does not support service providers other than sp-mode, mopera U
and Business mopera Internet.
• When using tethering, subscribing to a packet pack or packet flat-rate service
is highly recommended.
