Huawei MediaPad S7-301u Front Camera Replacement

Introduction

A front-facing camera is a camera in the tablet that is usually situated on the front of the device just above the screen. It is a good piece of hardware to use as a webcam or taking selfie with it. You can use the front-facing camera in conversations over communication apps like Skype, Google Hangouts, WhatsApp, etc. If the front camera does not work properly, you will either have to do some troubleshooting to check and see if it is a hardware problem, or the front camera might simply need a replacement.
