Warm Tips
1. Most of Android phone with usb c or micro usb ports devices (Such as: Samsung, LG, Google nexus, HUAWEI) could support the transmission of video and voice at the same time.
Other Android phone needs an external audio cable
2. The USB Power Cable should be connected with power socket, it isn't recommended to power by TV set directly. Since the current of the TV is usually less than 2A, the data cable will not work properly.
3.This adapter cable can support to mirror YouTube/ Office/ Safari/ Chrome/ FaceTime, While NOT support NETFLIX / Amazon Video/ DIRECTV/ hulu. And all of the paid videos in the Apps.
4.Please choose the right adapter, 5V/2A for Android phones. If lower voltage, it may not work very well.
