What to inspect first on a OnePlus AMOLED panel
Start with black and gray for retention and uniformity, then move to white and primary colors for tint and pixel defects.
This gives you a quick but broad picture of whether the panel remains clean and balanced.
How to test in realistic conditions
Use stable indoor lighting and compare several brightness levels if possible. Some issues are more visible when brightness drops.
Disable stronger color enhancements temporarily if you want a more neutral reading of panel behavior.
How to decide if a defect matters
Minor flaws may be acceptable on a cheaper used phone, but central burn-in, obvious tint, or clear dead pixels reduce long-term value.
Always judge the result together with price and overall device condition.
