take longer to fully charge the battery.
While the device is charging, the touch screen may

this happens, unplug the USB power adapter from
the power outlet or unplug the USB cable from the
device.
While charging, the device may heat up. This is

normal and should not affect your device’s lifespan or
performance.
If your device is not charging properly, bring your

device and the charger to a Samsung Service Centre.
When the battery is fully charged, first unplug the USB

To save energy, unplug the USB power adapter when
not in use. The USB power adapter does not have a
power switch, so you must unplug the USB power
adapter from the outlet to interrupt the power supply.
The USB power adapter should remain close to the
socket when in use.
