Used buyer checklist

|---|---|
| Screen | Check for AMOLED burn-in, green/pink lines and dead pixels on a full white and grey screen |
| Software support | Updates ended in 2025 |
| Network lock | Confirm it's factory unlocked and takes your MTN/Glo/Airtel/9mobile SIM |
| Samsung account / FRP | Make sure the previous owner's Google and Samsung accounts are removed |
| Water resistance | IP68 when new — seals weaken with age and repairs; don't rely on it |
| Heat | Exynos models run warmer under gaming — test for 10 minutes before paying |
