Phone Checker – Device Studio

Lumina Device Studio is a professional-grade phone and device checker for refurbishers, resellers, and anyone buying or selling used phones. Run a full diagnostic before you buy or hand over a device.
► WHAT YOU CAN DO
• Device identity – View brand, model, Android version, API level, RAM, storage, and Android ID in one place.
• IMEI & blacklist check – Enter the IMEI to verify status against supported databases and spot blacklisted devices.
• Warranty helper – Quick links to official warranty and authenticity pages for major brands so you can paste IMEI or serial number.
• Hardware tests – Test screen (full-screen colors for dead pixels), camera, microphone, speaker, sensors, WiFi, Bluetooth, battery, and fingerprint in guided steps. Mark each as Pass or Fail.
• Fake phone detection – Compare detected specs (e.g. RAM, storage) with known official values to flag possible clones or misreported hardware.
• Used phone checklist – Follow a structured pre-purchase checklist: physical condition, screen, IMEI, battery, camera, connectivity, storage, and account removal.
• PDF report – Generate a shareable inspection report (device info, IMEI result, hardware tests, checklist) and save it as a PDF.
