Quality & Testing Process
Every screen at iPartsMall is checked twice: once when the batch arrives from the factory, and once again on the day it ships. We do not spot-check — each individual unit goes through the full sequence below before it is packed.
1. The 7-point test every screen passes before dispatch
| Test | How we do it | Pass standard |
|---|---|---|
| Appearance | Multi-angle inspection under strong light | No scratches, chipped edges, bubbles or dirt |
| Solid-colour display | Full-screen red, green, blue, white and black | No bright or dead pixels, no stains, no backlight bleed |
| Greyscale | Greyscale test patterns | No banding, no colour cast |
| Touch | Full-screen swipes plus multi-point touch | Responsive everywhere, no dead zones, no drift |
| Brightness | Maximum brightness | Even across the panel, no dark corners |
| Connector & flex | Visual check of the gold fingers | No oxidation, no creases, no deformation |
| Power-on test | Panel connected and lit | Display and touch both confirmed working |
2. What we count as a defect
So there is no argument later, here is the standard we hold ourselves to. Report the issue before you install the screen, with a clear photo, and it falls under warranty:
| Issue | What it looks like | Our answer |
|---|---|---|
| Bright dot | A point that stays lit on a black screen | Two or more, or any in the central viewing area — replaced |
| Dark dot | A black point on a white screen | Three or more — replaced |
| Stains / backlight bleed | Patchy or glowing edges and corners | Visible in normal use — replaced |
| Fine scratch | Only visible at an angle under strong light | Not a functional defect; we look at a fair case-by-case solution |
| Bubble in the bonding layer | Air pocket inside the laminate | Send a photo — we judge whether it is production or handling and replace if it is ours |
3. How we pack
- Anti-static bag, then a thick bubble wrap layer, then a rigid box
- No movement inside the box — nothing rattles when shaken
- Outer carton marked FRAGILE (“FRÁGIL / NÃO EMPENHAR” on Brazil routes)
- A short installation hint card inside every parcel
4. If something is still wrong
Report any fault first and do not install the screen. Most “not working” reports are a flex cable that is not fully seated — disconnect the battery, re-seat the connectors until they click, and test again. If it still fails, message us with a short video: we replace or refund, and for quality problems we pay the shipping. Full details in our Refund & Returns Policy.
