Check device specs
See the model, operating system, CPU threads, GPU, RAM and screen resolution of a phone or laptop in the browser, and compare them with what the seller claims.
✓ Pass if
- Operating system, resolution and GPU match the specs the seller gave
✗ Fail if
- Specs differ from the listing (older model, replaced parts, refurbished clone)
