Testing note: Large iPhone and Android devices can feel similar in hand but report different CSS viewport widths, heights, DPR, and browser UI behavior. Test both when mobile bugs are important.

Frequently asked questions

Can Android and iPhone with similar sizes have different viewport widths?

Yes. OS scaling, browser UI, DPR, and display mode can change the effective CSS viewport.

Which phone should I test first?

Use both an iPhone and Android reference for important mobile flows because browser behavior can differ.

Does DPR explain screenshot differences?

Often yes. DPR affects how CSS pixels map to physical pixels and how image assets appear.
