The India-market vivo Y400 5G stands out for its larger listed battery, faster rated charging and higher water-and-dust resistance. The Samsung Galaxy A27 5G is the more compelling fit if you value Samsung’s stated software-support period, its listed chipset, or microSD expansion. These are specification-based distinctions, not proof of which phone performs better in everyday use.
One important naming caveat: Indonesia also has a vivo Y400, but it is a different model. This comparison uses the India Y400 5G and Samsung’s US-published Galaxy A27 5G specifications; prices below are separate market snapshots, not a like-for-like regional price comparison.

Those figures describe capacity and supported charging power, not guaranteed battery life or a specific time to recharge. Actual results depend on usage, settings, temperature, charger and other conditions. Vivo’s product page lists its supplied charger support; check the local box contents and regional listing when buying.
Which has better water and dust resistance?
On their published ratings, the vivo Y400 5G’s IP68 and IP69 ratings are higher than the Galaxy A27 5G’s IP64. That does not make either phone waterproof or guarantee protection in every situation.
Vivo specifically says underwater photography should be limited to fresh water, a maximum depth of 2 metres and no more than 30 minutes per use. It also states that damage caused by liquid immersion is not covered by warranty. Treat the rating as a defined resistance specification, not permission to expose the phone to water without risk.

How do the displays, processors and cameras compare?
Display
Both phones list FHD+ AMOLED-family displays with refresh rates up to 120 Hz. The vivo is 6.67 inches and the Samsung is 6.7 inches, so their stated screen sizes are close. Vivo lists 1,800-nit local peak brightness; Samsung’s cited table does not provide a directly comparable peak-brightness figure. Separate manufacturers’ brightness claims should not be treated as equivalent lab measurements.
Processor
Vivo lists a Snapdragon 4 Gen 2, while Samsung lists a Snapdragon 6 Gen 3; both are described as 4 nm platforms. Samsung’s named chipset is the higher-tier platform, but the available specifications do not establish a measured speed advantage in these exact phones. No comparable independent benchmark result is available here to determine real-world performance.
Rank #3
- Compatible with vivo Y400 5G Phone Case Cover
- Magnetic ring design. Compatible with most wireless magnetic products on the market, such as wireless chargers, magnetic car mounts, magnetic batteries, and magnetic wallets.
- The phone case features a dual-layer TPU+PU construction for a comfortable, non-slip feel. Corner airbags provide drop protection to safeguard your device.
- Perforated design enhances airflow for accelerated heat dissipation. Precise cutouts ensure full functionality of all ports, buttons, and cameras.
- Raised edges around the screen and rear camera elevate these components off the surface, effectively protecting them from scratches.
Cameras
Samsung’s listed rear setup comprises a 50 MP wide camera with optical image stabilization (OIS), a 5 MP ultra-wide and a 2 MP macro camera. Vivo lists a 50 MP main camera and 2 MP secondary camera. Vivo’s listed 32 MP front camera has a higher resolution than Samsung’s 12 MP front camera. Megapixel counts and camera features alone do not establish which phone takes better photos or video.
Quick wins for a faster PC:
Repair Windows errors before they cause bigger problemsFix Now →Scan for outdated or missing drivers - takes under a minuteDriver Scan →Which phone offers more storage or expansion?
The India Y400 5G is listed with 8 GB RAM and either 128 GB or 256 GB storage; its cited specification page does not list ROM expansion. Samsung’s US table lists a 6 GB RAM/128 GB configuration and microSD support up to 2 TB. Confirm the exact local Samsung configuration and Vivo bundle before comparing prices, because specifications and available SKUs can vary by market.
Which phone has the stronger software-support commitment?
Samsung gives a specific duration in its US announcement: up to six generations of Android and One UI upgrades and up to six years of security updates, with the security period measured from the initial global launch. Samsung describes this as its commitment to long-term support. The cited vivo India specifications show Android 15 with Funtouch OS 15 but do not state a matching support-duration promise, so a direct commitment comparison cannot be made from these sources.

Check the Vivo model before you buy
Do not assume every phone called vivo Y400 has the India Y400 5G specifications. Vivo’s Indonesia-market Y400 is a distinct model: its listed specifications include Snapdragon 685, 44 W charging and UFS 2.2 storage, rather than the India Y400 5G’s Snapdragon 4 Gen 2, 90 W charging and UFS 3.1. Indonesian prices are in rupiah and should not be applied to the India variant.
Compare the market name and full model details on the seller page with the manufacturer page for your country: India vivo Y400 5G specifications and Indonesia vivo Y400 specifications.
