Galaxy Z Series Screens

Screen Grades — what wholesale buyers check (Galaxy Z Series Screens)

Replacement screens are graded, and the grade decides your margin, your comeback rate and whether the customer books with you again. The key split is substrate: soft OLED flexes, hard OLED is rigid glass and more brittle. Incell LCD folds touch into the display stack; it is the cheapest route for an OLED phone, at the cost of brightness and power draw. Galaxy Z Series Screens stock is graded honestly, with the grade written on the listing rather than left to the buyer to discover.

Frames and adhesives are as much a part of the repair as the panel, which is why a grade list, not just a price list, is what a serious buyer asks for.

Specs and checks that matter

• Bench test: Touch, display, ghost-touch and true-tone are checked before an order is packed
• Common misdiagnosis: Roughly one in three "screen faults" traced to a bench actually turns out to be the flex or a software state
• Grade scale: Original New, Original Pull, OEM Refurb, OEM Grade, Soft OLED, Hard OLED, FHD Incell, HD Incell/TFT
• OLED types: Soft OLED is flexible and absorbs drops; hard OLED is rigid glass and more brittle at the corners
• Substrate check: Flex carries a factory code (JK, GX, ZY, DL, YH) — it identifies the actual production line

Buyer questions

What do the grades mean?

Grades run from original new through pull, OEM refurb and the incell tiers, and every listing states which one it is.

How do I read the grade ladder?

Highest to lowest: original new, original pull, refurbished original, OEM-grade aftermarket, soft OLED, hard OLED, FHD incell, and budget incell or TFT.

Soft OLED vs hard OLED — what is the real difference?

Soft OLED uses a flexible substrate and survives drops; hard OLED uses rigid glass, is cheaper, and cracks more easily at the corners.

Is OLED or LCD better for a phone that shipped with OLED?

An OLED phone converted to LCD loses true blacks, brightness and colour depth, and draws more power — quote it as a clearly explained budget option only.
