If the power is enough, The mobile phone will boot. 6 ● Turn off the phone Long press the power key until a menu will show. Choose “Power off’’ to turn off the phone. ● Reboot the phone Option 1: Long press the power key until a menu will show. Choose “Restart” to restart the phone. Option 2: Long press the power key till 10 seconds to auto restart the phone. ● Airplane mode Drop the status bar ,click on the airplane mode icon. ● Lock the screen Option 1: Press the power key to turn off the screen and lock it Option 2: The screen will auto lock if you don't use the phone for a while. ● Unlock the screen Option 1:Press the power key, and then swipe the screen upward for unlocking. Toolbox operation ● Enable the toolbox Swipe the touch panel from top to bottom,then can enable the toolbox. 7 Touch operations ● Touch: To act on items on the screen, such as application and settings icons, to type letters and symbols using the onscreen keyboard, or to press onscreen buttons, you simply touch them with your finger. ● Touch & hold: Touch & hold an item on the screen by touching it and not lifting your finger until an action occurs. ● Drag: Touch & hold an item for a moment and then, without lifting your finger, move your finger on the screen until you reach the target position. You drag items on the Home screen to reposition them and you drag to open the Notification panel. ● Swipe or slide: To swipe or slide, you quickly move your finger across the surface of the screen, without pausing when you first touch (so you don’t drag an item instead). For example, you slide the screen up or down to scroll a list, and in some Calendar views you swipe quickly across the screen to change the range of time visible. ● Pinch: In some applications (Such as Mapsand Gallery) you can zoom in and out by placing two fingers on the screen at once and pinching them together (to zoom out) or spreading them apart (to zoom in). ● Rotate the screen: On most screens, the orientation of the screen rotates with the phone as you turn it from upright to its side and back again. You can turn this feature on and off. Warnings and notes IMPORTANTINFORMATION ON SAFE AND EFFICIENT OPERATION. Read this information before using your phone.
