The right choice depends first on which vivo Y400 you mean: vivo Indonesia lists a Snapdragon 685 Y400, while 91mobiles compares a different Y400 5G with a Snapdragon 4 Gen 2. Those variants should not be treated as the same phone. Nothing’s Phone (4b) has a 6.77-inch 120 Hz display and Android 16, but there is no reliable, universal price difference between the two phones because the available prices come from different markets and configurations.
Check the exact vivo Y400 variant first
The name “vivo Y400” does not identify one unambiguous set of specifications in the available listings. vivo Indonesia’s official page describes a Y400 with a Snapdragon 685, Android 15, Funtouch OS 15, and IP68/IP69 ratings. By contrast, 91mobiles’ comparison entry calls its model the vivo Y400 5G and lists a Snapdragon 4 Gen 2. Confirm the phone’s full model name, country version, and connectivity before relying on a comparison or buying a listing.
The figures below keep those records separate rather than combining specifications from different variants.

How the phones compare in daily use
Display
Nothing specifies a 6.77-inch Super AMOLED panel with adaptive refresh up to 120 Hz. 91mobiles lists a 6.67-inch AMOLED panel for its Y400 5G entry, but that is third-party information and does not establish the display specification of vivo Indonesia’s Snapdragon 685 Y400. The available figures do not support a fully verified, like-for-like screen comparison until the vivo variant is confirmed.

Chipset and performance
The listed chips differ by vivo variant: Snapdragon 685 for the Indonesian Y400 and Snapdragon 4 Gen 2 for 91mobiles’ Y400 5G entry. The same comparison lists Snapdragon 6 Gen 4 for the Phone (4b). These chipset names alone do not establish real-world speed, gaming performance, or thermal behavior; no comparative benchmark or hands-on test is available here.
Cameras
Nothing’s product page highlights a 50 MP main camera and 4K video. 91mobiles lists a 50 MP rear camera and 32 MP front camera for the Y400 5G entry. Megapixel counts describe sensor resolution, not image quality: they do not establish which phone takes better photos, handles low light better, or records better video overall.

Battery
Battery capacity varies by Phone (4b) market: Nothing’s Malaysia page lists 5,200 mAh, while its India configuration is 6,000 mAh. 91mobiles lists 6,000 mAh for the Y400 5G entry, but the cited evidence does not give a matching battery figure for the Indonesian Snapdragon 685 Y400. Capacity is not a measured battery-life result, and no comparable endurance test is available.
Software and durability
The official Indonesian Y400 page lists Android 15 with Funtouch OS 15 and IP68/IP69 ratings; Nothing lists Android 16 with Nothing OS. The available sources do not securely establish comparable software-update support periods for the specific regional variants, so check each manufacturer’s local support terms rather than assuming a number of update years.

Price difference: compare within one market
There is no dependable global price gap to quote from these listings. The official vivo prices are in Indonesian rupiah, Nothing’s official price is in euros for Spain, and 91mobiles displays third-party Amazon prices in rupees. They are not matched by country, seller, date, or memory tier.
| Listing | Configuration | Displayed price | Source and qualification |

To calculate a useful difference, compare current local listings for the exact variants at the same time, with the same storage capacity and a clearly identified seller. Do not convert these regional prices into a supposed head-to-head gap: exchange-rate conversion would not account for local pricing, taxes, stock, or retailer discounts.
Rank #4

Which phone should you choose?
- Consider the Phone (4b) if its regional configuration and local price suit you, and you value its officially listed 6.77-inch 120 Hz display and Android 16.
- Consider the Indonesian vivo Y400 if that is the variant sold in your market and its Snapdragon 685, Android 15/Funtouch OS 15, durability ratings, storage option, and local price meet your needs.
- Compare the Y400 5G separately if a seller is offering that model: verify that it is the Snapdragon 4 Gen 2 version rather than assuming the Indonesian Y400 specifications apply.
Before purchasing either phone, confirm the exact model and regional version on the seller’s listing, along with memory configuration, network compatibility, warranty, and current price. A universal winner cannot be established from the available specification and price listings alone.
