vivo's slimmest 5G phone at 7.49mm, with a genuinely bright 3D-curved AMOLED (4,500 nits peak) that's rare at this price. Camera hardware is the clear trade-off — a plain 50MP+2MP dual setup with no ultrawide or telephoto. India-official; no confirmed US/UK/EU retail channel.

The Y400 Pro is for a buyer who prioritizes a slim, premium-feeling design and a genuinely bright display over camera versatility or top-tier gaming performance. 91mobiles' review calls it directly "one of the most stylish options in the sub-Rs 25,000 segment," specifically for pairing a slim curved-display design with capable everyday cameras and thoughtful software features. It suits someone who values in-hand feel and battery life above raw benchmarks — the phone's slim profile and light weight consistently earned praise across every review sourced here. It's a weaker fit for anyone who wants an ultrawide lens or class-leading performance, since 91mobiles' own verdict is direct that "the raw performance isn't class-leading" compared to rivals in the same price bracket.
Design is the phone's clearest calling card, and it's backed by real, measured numbers — 91mobiles confirms the Freestyle White variant reaches just 7.44mm thick, genuinely the slimmest of the three colorways, while still housing a substantial 5,500mAh battery with 90W fast charging. Display quality earned real, specific praise too: GSMArena's coverage confirms a local peak brightness of 4,500 nits with HDR support on the curved AMOLED panel, a genuinely strong figure for this price tier. The phone's slimness didn't come at the cost of comfort either — 91mobiles found it "comfortable when holding it with one hand," and specifically thinner than direct rivals like the Motorola Edge 60 Fusion and OnePlus Nord CE 5 in a side-by-side comparison. Software extras add real, if minor, polish too — Digit's review notes the customizable Dynamic Light ring under the cameras, which can be set to glow for notifications, music playback, or charging status.
The absence of an ultrawide lens is the most consistently disclosed camera limitation — 91mobiles' own comparison confirms the phone "lacks an ultrawide lens," a real capability gap against similarly priced rivals that increasingly include one. Performance is a genuine, measured step behind close competitors too: 91mobiles' direct testing found the Dimensity 7300 chipset "doesn't really keep up with other phones in the price range" during moderate-to-heavy gaming and day-to-day multitasking, despite the phone's UFS 3.1 storage. Daylight photography has a real, specific weakness as well — 91mobiles found highlights "can get washed out" in 1x shots, portraits, and selfies, making bright scenes look less polished than the phone's otherwise strong night photography. Gaming graphics settings are capped lower than some rivals too: Digit's testing found the phone "only supports Smooth + Extreme graphics settings (90 FPS) in BGMI," a real ceiling for competitive mobile gamers. The phone also remains India-exclusive as of this listing, with no confirmed retail channel in the US, UK, or EU for buyers outside that market.
