Assemble Your Device

Install the SIM Card and a
MemoryCard
When you subscribe to a cellular network, you are
provided with a plug-in SIM card. During activation,
your SIM card is loaded with your subscription details,
such as your Personal Identification Number (PIN),
available optional services, and other features.
Warning: Please be careful when handling the SIMcard
to avoid damaging it. Keep all SIM cards outof reach of
small children.
You can also install an optional microSD™, microSDHC™,
or microSDXC™ memory card (notincluded) to add more
memory space to yourdevice. A memory card can be
installed at any time. It is not necessary to install it
prior to using the device.
Note: Your phone’s SIM card is preinstalled. These
instructions are for reference only.

eject the internal SIM card/Memory card tray.
1. Insert the removal tool into the hole on the
SIMcard/Memory card tray, and then push until the
tray pops out.

contacts facing down.

Set Up Your Device 8
4. Slide the SIM card/Memory card tray back into
theslot.
Note: Your device is IP68 rated for dust and water
resistance. To maintain the water-resistant and
dust‑resistant features of your device, make sure
that the SIM card/Memory card tray openings are
maintained free of dust and water, and the tray is
securely inserted prior to any exposure to liquids. For
more information, refer to “Maintaining Water and Dust
Resistance” on page259.
Charge the Battery
Note: You should dry the inside of the charging port
before inserting a power connector to charge your
device. If the charging port is not fully dry, your device
may operate abnormally. For example, it may charge
more slowly or overheat. For more information, refer to
“Maintaining Water and Dust Resistance” on page259.
Your device is powered by a rechargeable, standard
Li-Ion battery. A USB charger (charging head and USB
cable) is included with the device for charging the
battery from any standard outlet.
The battery comes partially charged. You can use the
device while charging.
Note: For fastest charging times, use the Adaptive
Fast Charger that came with your device. This charger
provides faster charging only when connected to
devices that support Adaptive Fast Charging.

Set Up Your Device 9
1. Insert the USB cable into the USB charger/
Accessory port.
Caution: Use only charging devices and batteries
approved by Samsung. Samsung accessories are
designed for your device to maximize battery life. Using
other accessories may invalidate yourwarranty and
may cause damage.
2. Connect the USB cable to the charging head, and
then plug the charging head into a standard outlet.
3. Unplug the charging head from the outlet and
remove the USB cable from the device when
charging is complete.
Note: This device is also compatible with wireless
charging devices approved by Samsung, which are
soldseparately.
When to Charge the Battery
When the battery is low and only a few minutes of
operation remain, the device sounds a warning tone at
regular intervals.
In this condition, your device conserves its remaining
battery power by dimming the screen.
When the battery level becomes too low, the device
automatically turns off.
For a quick check of your battery level:
►View the battery charge indicator located in the top
right corner of your device’s display. Asolid color
( ) indicates a full charge.

Set Up Your Device 10
You can also choose to display a percentage value.
Viewing a percentage value can provide a better idea
of the remaining charge on the battery. For more
information, see “Battery” on page212.
While charging, the device and the charger may
become hot when using wireless charging or fast
charging. This does not affect the device’s lifespan or
performance and is in the device’s normal range of
operation.
The charger may stop charging if the battery becomes
too hot.
If the device heats up while charging the battery:
1. Disconnect the charger from the device and close
any running apps.
2. Wait for the device to cool down, and then begin
charging the device again.
• If the lower part of the device overheats,
check for damage to the connected USB cable.
Replace the damaged USB cable with a new
Samsung-approved cable.
If using a wireless charger, do not place foreign
materials between the device and the wireless charger.

connect a Micro-USB cable (such as from your old
device) to your new device for charging with the
charging head, or for connecting to a computer.
