Testing & quality control

Phonecheck certified: a 40+ point inspection on every unit

Nothing leaves our facility untested. Every device is run through Phonecheck diagnostics, and here is exactly what happens between intake and the moment it is sealed for your order.

  1. 01

    Intake & IMEI verification

    Each unit is scanned and checked against carrier and blacklist databases. Anything reported lost, stolen, or financed is rejected at intake.

  2. 02

    Phonecheck diagnostic pass

    We test with Phonecheck, the industry-standard diagnostic platform. It runs a 40+ point sequence covering hardware sensors, connectivity, and system integrity, and produces a verifiable certificate per IMEI.

  3. 03

    Battery testing

    Battery health and cycle count are recorded. Units below our threshold are re-graded or pulled.

  4. 04

    Face ID / Touch ID testing

    Biometrics are enrolled and verified. Any failure is disclosed on the sheet before you buy.

  5. 05

    Camera & optics

    Front, rear, ultra-wide, and telephoto lenses tested for focus, flash, and sensor defects.

  6. 06

    Charging & port test

    Wired and wireless charging, port continuity, and accessory detection.

  7. 07

    Speaker, mic & haptics

    Earpiece, loudspeaker, all microphones, and vibration motor confirmed working.

  8. 08

    Cosmetic grading

    Screen and housing inspected under controlled lighting and assigned a documented grade.

  9. 09

    Data wipe & reset

    Every device is factory wiped, activation-lock cleared, and set to a clean out-of-box state.

  10. 10

    Final QC before shipping

    A second technician re-verifies grade, IMEI, and accessories before the unit is sleeved and packed.
