Next Loop & Samsung: Galaxy Grade Excellence

Samsung devices require a unique approach to grading, especially regarding OLED screens. We break down our stringent testing for the S-Series and Foldables.

The Android Flagship

Samsung remains the volume leader in the global smartphone market. For our B2B partners, stocking the Galaxy S-Series (S23, S24, S25) is essential to offering a complete portfolio.

The OLED Challenge

Samsung displays are beautiful, but they can be fragile. "Screen Burn" (permanent discoloration) is the enemy of refurbished Samsung value.

  • Our Standard: We do NOT sell devices with visible screen burn as "Grade A" or "Grade B". These are strictly segregated into "Grade C" or "Burn Stock".
  • Shadow Check: We test devices in a dark room with a pure white background to identify even faint pink shadowing common in heavy-use AMOLED panels.

Knox Security

Samsung's Knox security layer is robust. We check the Knox Counter (0x0 vs 0x1) on every device.

  • If the Knox counter is tripped (indicating previous rooting or unauthorized software modification), the device is rejected from our premium stock, as secure banking apps may not work.

Foldables (Z Flip / Z Fold)

We handle foldables with extreme caution.

  • Hinge Test: We robotically cycle the hinge to listen for dust intrusion or "crunching".
  • Crease Inspection: We inspect the inner screen protector and the crease for any signs of micro-fractures.
