Introduction

Video Overview

Step 1

              Test The Flood Illuminator               

• The phone keeps sending messages: ‘move iPhone a little lower/higher’ during the setting up process of Face ID. Based on REWA exclusive repair tricks, let’s start with the Flood Illuminator.
• In our daily repair work, we can test the Proximity Sensor and the Ambient Light Sensor to confirm whether the Flood Illuminator is working normally.
• Let’s make a phone call to confirm whether the Proximity Sensor is working. The Proximity Sensor works normally.

Step 4

              Observe The Dot Projector               

• At the Portrait Mode, there is no flashing red light from the Dot Projector.
• We can confirm now that the Dot Projector has malfunctioned.
• This is the fault and the problem cannot be fixed.
• The three parts ( infrared camera, flood illuminator and dot projector) are paired to the phone. Damage of any one of them can cause Face ID failure and such an issue is irreparable.
