Back Market Phone Check Guide: How to Inspect Refurbished Devices
Bought a refurbished phone on Back Market? While Back Market operates one of the world’s most trusted refurbished marketplaces with rigorous merchant grading, testing the device within your first 30 days is vital to catch hidden battery degradation, non-OEM replacement parts, or unexpected carrier locks before your return window closes.
This guide walks you through the essential 7-step inspection checklist for any Back Market smartphone (iPhone, Samsung Galaxy, or Google Pixel) to ensure you received the exact cosmetic condition and technical specifications you paid for.
The 7-Step Back Market Phone Inspection Protocol
- 1. Verify the IMEI & Blacklist Status: Open your dialer and enter
*#06#. Compare the 15-digit IMEI with the receipt and box label. Run our Free IMEI Blacklist Check to verify the device was not flagged on international GSMA registries. - 2. Check Battery Health & Capacity: On iPhone, navigate to Settings > Battery > Battery Health & Charging. Back Market guarantees at least 85% Maximum Capacity. On Android, check Settings > Battery or use an app like AccuBattery to measure charge cycles. If battery health is below 85%, request a free replacement immediately.
- 3. Inspect Parts & Service History (iOS): Go to Settings > General > About > Parts & Service History. iOS flags third-party repairs with "Unknown Part" for screens, cameras, or batteries. While third-party parts are common in refurbished devices, poor-quality screens can cause True Tone failure or touch latency.
- 4. Test Carrier Freedom with an Active SIM: Insert a physical SIM card or activate an eSIM from your carrier. Make a test call and disable Wi-Fi to test mobile data. Confirm in Settings > General > About > Carrier Lock that it states "No SIM restrictions".
- 5. Screen & Touch Digitizer Diagnostics: Test for dead pixels, OLED burn-in, and touch sensitivity. Dial
*#0*#on Samsung devices to enter hardware testing mode. On iPhone, drag an app icon smoothly across all four corners and the center of the display. - 6. Microphone, Speaker & Biometric Sensors: Record a voice memo, test the front and rear cameras in 4K, and configure Face ID / fingerprint authentication. Face ID failure often indicates an uncalibrated third-party front display replacement.
- 7. Water Seal & Casing Integrity: Remember that refurbished phones no longer retain their factory IP67/IP68 water resistance seals because the adhesive is broken during refurbishment. Never submerge a refurbished device in water.
Back Market Condition Grades Compared
Back Market categorizes cosmetic condition into three distinct grades. Hardware performance, camera clarity, and battery health (>=85%) are identical across all three tiers:
| Back Market Grade | Screen Condition | Body / Frame Condition | Recommended For |
|---|---|---|---|
| Premium | Flawless, pristine condition; zero visible scratches | Zero visible scratches or scuffs from 8 inches away; OEM specs | Gift purchases and users demanding mint condition |
| Excellent | Screen is pristine with no micro-scratches when turned on | Micro-scratches barely visible from 8 inches away; no dents | Best overall balance of price and near-new appearance |
| Good / Fair | Micro-scratches may be visible with screen off, invisible when lit | Visible scuffs, micro-dents, or paint wear from normal prior use | Budget-conscious buyers who use protective cases anyway |

Start with free IMEI identification to confirm what the device is before deciding whether any additional status report is needed.
What to Do If You Find an Issue
If your device fails any test during your 30-day trial period, log into your Back Market account, click "Get Help" on the order summary, and submit photos or diagnostic screenshots. Back Market provides a prepaid return shipping label and facilitates a replacement or full refund within 3 to 5 business days.
