Honor 400
By Muhammad Tahir · Updated June 2026 · how we review
A 200MP OIS main camera, a 5,000-nit AMOLED and six years of updates to May 2031, for $350. The Honor 400's spec sheet reads like a phone twice the price — the plastic frame and the lack of US availability are where reality intrudes.

Frequently asked questions
How long will the Honor 400 be supported?
Six years of OS upgrades and six years of security patches from its May 2025 release, so support runs to May 2031. Honor publishes this commitment, and six years at $350 matches Samsung's A-series policy while offering a considerably better camera.
Is a 200MP camera better than a 50MP one?
Not automatically, but here it helps. The Honor 400's 200MP sensor bins down to around 12.5MP for normal shots, producing clean detailed images, and the high resolution means a 2x crop still yields a genuinely sharp result — effectively giving you a free short telephoto. The OIS is what makes it work in lower light; resolution alone would not.
Can I buy the Honor 400 in the US?
Not officially. Honor does not sell through US carriers or retail, so availability is limited to grey-market importers. That means no warranty, possible missing US 5G bands, and no carrier support. Check band compatibility with your network before buying, and treat any repair as your own problem.
How does the Honor 400 compare to the 400 Pro?
The Pro costs roughly double at $700 and is a genuine flagship: a Snapdragon 8 Gen 3 instead of the 7 Gen 3, a real 50MP 3x telephoto, 100W wired plus 50W wireless charging, IP68/IP69 rating, and a glass-and-aluminium build. Both share the 200MP main sensor and the six-year support window. The standard 400 is much better value; the Pro is much better hardware.
