The iPhone 13 OLED panel is gently lifted using controlled suction and specialized picks to protect sensitive ribbon flex cables.
Microscope Sensor Flex Evaluation
Technicians inspect the top sensor flex under 45x magnification to detect liquid corrosion, torn traces, or misaligned light guides.

Frequently Asked Questions & Diagnostic Scenarios
Q: Why does my iPhone 13 screen go black during phone calls and won't turn on?
This problem occurs when the infrared proximity sensor in the top notch fails or is blocked by dirt, misaligned screen glass, or moisture corrosion. Because the phone mistakenly believes it is still held against your ear, it keeps the screen locked black. Phone Repair Centre fixes the sensor circuitry in 45 minutes while preserving your factory Face ID.
Q: Will fixing the proximity sensor break Face ID on iPhone 13?
Not at Phone Repair Centre. Apple pairs the top sensor flex to the logic board for Face ID security. Our technicians use microsoldering to replace only the faulty proximity component, keeping your original Face ID sensor 100% functional.
