				m‖“?
			“K?
	before turning on the device.

	another device, the battery will drain quickly. To avoid losing power during a data
c‘
	transfer, always use these apps after fully charging the battery.
•	Using a power source other than the charger, such as a computer, may result in a slower
	charging speed due to a lower electric current.
•	The device can be used while it is charging, but it may take longer to fully charge the
	battery.
•	If the device receives an unstable power supply while charging, the touchscreen may not
	function. If this happens, unplug the charger from the device.
