Why won't my device charge?I’ve been trying to charge my tablet but it won’t turn on and I don’t know what to do. Please help!
回答“Why can't I see my screen?”If the display is faintly visible, try going into the settings and increasing the screen brightness. If the display is still too dim or not responding to the brightness increase, you may need to replace the back-light. If the screen is damaged in any way, you might need to replace the screen in order for it to power up.
回答“Why is my camera not working?”Check to see if anything is blocking the camera lens. Make sure there is a good amount of lighting when taking a picture. If the camera still is not functioning, you may need to replace the camera.
