The Asus Smartphone FFC IO Board Cable is the flexible flat connector that links the IO board—often responsible for charging, audio, or buttons—to the mainboard in your Zenfone. If your phone isn’t charging correctly, buttons are unresponsive, or the audio jack fails, replacing this cable with an official Asus part can restore core device functions.
