Who should pick which
Beyond the scores — our take on each phone and the buyer it actually suits.
The Razr Ultra 2026 packs a genuine flagship — Snapdragon 8 Elite, a huge 7-inch main display, triple 50MP cameras — into a flip form factor, but its 4-year security promise and $1,499 price are tough sells against Samsung's longer-supported foldables.
Pick it if
- ✓ Flip-phone fans wanting flagship power
- ✓ Buyers who prioritize camera and display specs over long-term support
Skip it if
- ✗ You want the longest possible software support
- ✗ You need real optical zoom
The X300 Ultra's dual 200MP camera system and semi-solid-state battery make it Vivo's most ambitious phone yet, but it only just went on sale globally, so its full multi-year support window is still ahead of it.
Pick it if
- ✓ zoom-obsessed photographers
- ✓ buyers who want the newest flagship camera hardware
Skip it if
- ✗ you need US warranty coverage
- ✗ you want a slim, light phone

Frequently asked
How long is the Razr Ultra 2026 supported?
Motorola commits to three major Android upgrades and four years of security patches from its May 2026 release, so official support ends around May 2030 — short for a $1,499 flagship.
Does the Razr Ultra 2026 have a telephoto camera?
No. It relies on its 50MP main sensor cropped digitally for 2x-4x zoom rather than a dedicated telephoto lens, so image quality drops off noticeably beyond that.
How long will the Vivo X300 Ultra be supported?
Vivo hasn't published a separate written policy specific to the X300 Ultra at the time of writing, but based on the X300 and X300 Pro's official 5-year OS/7-year security commitment, buyers can reasonably expect the same, projecting support into around 2033.
Is the X300 Ultra sold in the US?
No. It launched in China in March 2026 and expanded to Europe, India, and parts of Asia and the Middle East by May 2026, but Vivo has not brought it to the US market, so any US unit is an import without official warranty.
