Why Marketplace deals need quick display checks
In-person local sales often leave less time for testing than store or refurbished purchases. That makes a short but effective screen checklist more important.
A few fullscreen patterns can reveal issues that a seller may never mention on the listing page.
The fastest in-person inspection flow
Run black, gray, and white first, then check primary colors if anything looks suspicious. This covers most common OLED risks in just a few minutes.
Pay special attention to the status bar, keyboard, and logo-like overlay zones where burn-in often develops.
How buyers should negotiate based on results
Small flaws may justify a lower price, while strong burn-in or obvious dead pixels can be a reason to walk away entirely.
A quick on-site test gives you real information instead of guessing based on the seller's description.
FAQ
Can I test a phone quickly during a Marketplace meetup?
Yes. A short fullscreen test sequence can reveal the biggest OLED issues in just a few minutes.
What should I check first in person?
Start with black, gray, and white because they reveal burn-in, banding, and tint the fastest.
Should display flaws affect the offer price?
Yes. Visible burn-in, dead pixels, and strong tint usually justify a lower offer or a decision to skip the deal.
