Check device specs
See the model, OS, CPU, GPU, RAM and screen resolution of a phone or laptop in your browser, and compare them with the advertised or claimed specs.
✓ Pass if
- Operating system, resolution and GPU match the advertised specs (or what the seller said)
✗ Fail if
- Specs differ from the listing (older model, replaced parts, refurbished clone)
When to check it
Open this page before any other test: when you look at a used device, when you collect one from a repair shop, or when a new device bought online arrives and you want to confirm it's the configuration you ordered. The browser reads these details from the device itself; nobody typed them in.
What often doesn't match the listing
- Screen resolution lower than the spec: a sign the screen was replaced with a cheaper one, or that it's a different model.
- GPU or CPU core count that doesn't match: a laptop with a different configuration, or a device built from mixed parts.
- An operating system version far older than the model: the software may have been downgraded, or the device hasn't been updated in a long time.
Note that browsers round some numbers for privacy. Memory, for example, is only a rough figure (a 12 GB phone may show 8 GB), and an iPhone won't tell websites its model name, so Soi Máy can only guess the range from the screen size. Cross-check in Settings › General › About (iPhone) or Settings › About phone (Android).
If the specs don't match
- Take a screenshot of this page as evidence, then ask the seller or repair shop.
- On a laptop, also check storage and memory in the system settings. More detail: how to check a used laptop.
- On Android, see how to check a used Android phone.
