Which is the better buy depends on which trade-offs matter to you—and on the price of matching configurations in your market.
At a glance: how the specifications compare
The Samsung figures below come from a comparison source, not a Samsung regional product page. The vivo specifications are from vivo’s India-market product page, so they should not be assumed to describe every Y21 5G sold elsewhere.

| Display | 6.7-inch, 1080 × 2340, 90 Hz, as reported by the comparison source | 6.74-inch LCD, 1600 × 720, up to 120 Hz; vivo says 120 Hz is supported only in certain scenarios |

| Chipset | Exynos 1330, as reported by the comparison source | MediaTek Dimensity 6300, according to vivo India |
| Ingress rating | IP54, as reported by the comparison source | IP65 for the India configuration, according to vivo |
| Software | Not stated in the cited comparison data | Android 16 listed for the India configuration |
Samsung specifications in this table are secondary-source figures and need confirmation against the local model. vivo’s regional memory, software and network details should likewise be checked against the version sold where you live.

On the figures reported, the Galaxy A17 5G has the sharper panel: its stated 1080 × 2340 resolution is higher than the Y21 5G’s 1600 × 720. That matters most for fine text and detailed images. The vivo’s 6.74-inch LCD is slightly larger by diagonal measurement and has a higher stated refresh ceiling, up to 120 Hz versus 90 Hz for the Samsung. Higher refresh can make supported scrolling and motion look smoother, but vivo qualifies 120 Hz as available only in certain scenarios.

vivo’s India overview also advertises 1200-nit sunlight brightness. That is a manufacturer-listed figure, not a like-for-like independent screen test. The comparison data does not establish the Samsung model’s brightness, so a direct brightness winner cannot be named from these figures.
Battery and charging: vivo’s specification advantage
vivo lists a 6500 mAh typical battery for the India Y21 5G and gives 6355 mAh as its rated capacity. Its product page lists 44 W charging and notes that actual charging power varies with conditions. The comparison source reports 5000 mAh and 25 W charging for the Galaxy A17 5G.

Those listed capacities and wattages favor vivo on paper, but they do not establish how long either phone lasts in everyday use or how quickly it charges in every situation. Screen settings, signal strength, workload, charger and other conditions affect results; no comparable controlled endurance or charging test is established here.
Camera options and performance
Rear and selfie cameras
The reported Samsung rear setup includes a main, ultrawide and macro camera, while vivo lists a 50 MP main camera alongside a 0.08 MP rear camera. That gives Samsung more listed rear-camera types to choose from. The comparison source also reports a 13 MP Samsung front camera, compared with vivo’s listed 5 MP. Megapixel counts and camera count alone do not establish photo quality, and no comparable camera testing is available to call a winner for image results.

- US Model – Global Connectivity – Compatible with Most GSM Carriers like T-Mobile, AT&T, MetroPCS, etc. Will Also work with CDMA Carriers Such as Verizon, Straight Talk. Please contact seller if you are unsure about carrier compatibility, as some MVNOs will not allow Carrier Unlocked devices. 5G bands are Specific to Americas, 4G LTE will work Globally.
Chipsets
The comparison source identifies an Exynos 1330 in the Galaxy A17 5G; vivo lists a MediaTek Dimensity 6300 for the India Y21 5G. Chipset names alone do not reliably predict day-to-day responsiveness, gaming performance or efficiency. No independent, controlled performance test is established for these two specific configurations.
Protection ratings and regional specifications
For its India Y21 5G, vivo lists an IP65 rating. The comparison source reports IP54 for the Galaxy A17 5G. These ratings describe ingress protection, not immunity from damage: neither should be treated as a guarantee that a phone will survive every spill, immersion or impact. Confirm the rating for the exact regional model, and follow each manufacturer’s care guidance.
Rank #4
The Y21 5G details cited here—including Android 16 and the Dimensity 6300—refer to vivo’s India configuration. Do not assume identical software, bands, memory or other specifications in another country. The available Samsung figures are also secondary-source reports rather than verified local Samsung specifications.
Price difference: compare the same market and configuration
There is no universal price difference: country, storage and memory configuration, seller, warranty and date all affect the amount. EligeMovil reported Spain offers checked on 15 September 2026 at €179 for the Galaxy A17 5G and €249 for the Y21 5G. Those dated observations are not guaranteed current prices; the same page also displayed a lower observed vivo offer.

Indian comparison results show different rupee prices and variant contexts, so they cannot be substituted for Spain prices or treated as a current, like-for-like comparison. Before deciding, check the checkout price for both phones in your country and match RAM, storage, seller terms and warranty. The date and configuration matter as much as the headline price.
Which phone should you choose?
- Choose the Galaxy A17 5G if a higher reported display resolution and more reported rear-camera options matter most. Confirm those specifications for the local Samsung model before buying.
- Consider the vivo Y21 5G if you prioritize its listed larger typical battery, faster wired charging, a 120 Hz refresh option or the India model’s IP65 rating. Check that the regional version has the specifications you want.
- Compare local offers before choosing either if the price gap is decisive. A dated offer for one market or a different storage variant does not establish which phone is cheaper for you.
These recommendations follow the listed specifications, not hands-on testing. The best choice is the one whose verified local configuration and current price fit your priorities.
