Samsung Galaxy A17 5G VS Vivo Y31 Pro 5G

In terms of physical form, the Samsung Galaxy A17 5G has a meaningful advantage in portability. At 192 g and 7.5 mm thick, it is noticeably lighter and slimmer than the Vivo Y31 Pro 5G, which weighs 208 g and measures 8.1 mm in thickness. That 16-gram difference is tangible during prolonged one-handed use or when carried in a pocket, and the lower volume (96.05 cm³ vs 102.41 cm³) confirms the A17 5G is the more compact device overall. The Y31 Pro 5G is marginally narrower (76.3 mm vs 77.9 mm), which can slightly ease thumb reach, but its greater weight and thickness offset that benefit for most users.

On environmental protection, the story flips. Both phones are rated water resistant, but their IP ratings differ in a key way: the Galaxy A17 5G carries an IP54 rating, while the Vivo Y31 Pro 5G steps up to IP64. The critical distinction is the first digit — dust protection. A rating of 5 means limited dust ingress protection, whereas a rating of 6 means the device is fully dust-tight. The water-resistance level (the second digit, 4) is identical on both, covering splashes from any direction. In dusty or outdoor environments — a workshop, a sandy beach, or an arid climate — the Y31 Pro 5G offers meaningfully stronger real-world protection.

Neither phone has a rugged build or a foldable form factor, so both target the mainstream segment. The Galaxy A17 5G wins on everyday ergonomics and portability, while the Vivo Y31 Pro 5G holds a clear edge in dust resistance. The better choice depends on the user's priority: those who value a lighter, slimmer handset will prefer the A17 5G, while those who frequently expose their phone to dusty conditions will benefit more from the Y31 Pro 5G's superior IP64 rating.

The most consequential difference here is panel technology. The Samsung Galaxy A17 5G uses an OLED/AMOLED display, while the Vivo Y31 Pro 5G relies on an LCD IPS panel. In practice, OLED delivers true blacks by switching off individual pixels, producing richer contrast and more vivid colors — advantages that are especially visible when watching video or using dark-mode interfaces. The A17 5G also supports an Always-On Display, a feature the Y31 Pro 5G lacks entirely, allowing users to check the time or notifications without waking the screen — a small but genuinely convenient daily benefit that is only possible because OLED panels can illuminate individual pixels without powering the full screen.

Where the Vivo fights back is in motion fluidity. Its 120Hz refresh rate edges out the A17 5G's 90Hz panel, meaning scrolling, animations, and gaming all appear marginally smoother on the Y31 Pro 5G. The pixel density gap is narrow — 393 ppi versus 385 ppi — and both render at a full 1080p resolution, so sharpness is effectively identical to the human eye at normal viewing distances. Screen size is virtually the same at roughly 6.7 inches on both devices.

Overall, the Galaxy A17 5G holds the stronger display advantage for most users. The jump from LCD to OLED is a more fundamental and perceptible quality upgrade than the step from 90Hz to 120Hz, affecting every moment of screen use — color richness, contrast depth, and the added utility of Always-On Display. The Y31 Pro 5G's higher refresh rate is a real perk for gamers or those who are particularly sensitive to screen smoothness, but for general use, the A17 5G's OLED panel is the more impactful differentiator.

Under the hood, the Vivo Y31 Pro 5G holds a substantial performance lead. Its MediaTek Dimensity 7300 chip, built on a 4 nm process, outpaces the Samsung Exynos 1330 (5 nm) in the Galaxy A17 5G across every measured dimension. The Geekbench 6 multi-core score tells the clearest story: 2932 on the Y31 Pro 5G versus 2048 on the A17 5G — a gap of roughly 43%. In real-world terms, this translates to faster app launches, smoother multitasking, and better handling of demanding workloads. The single-core scores are closer (1026 vs 980), meaning everyday single-threaded tasks feel more comparable, but sustained, parallel workloads clearly favor the Vivo.

The supporting hardware reinforces this gap. The Y31 Pro 5G's GPU runs at 1047 MHz compared to 800 MHz on the A17 5G, giving it a meaningful edge in graphics-intensive tasks like gaming. Its RAM also operates at 6400 MHz — double the A17 5G's 3200 MHz — which reduces memory bottlenecks when switching between apps or loading large assets. Equally significant is the Y31 Pro 5G's 16 GB maximum memory support, versus the A17 5G's cap of 8 GB. While both ship with 8 GB, only the Y31 Pro 5G can be configured with more RAM, offering better long-term headroom as apps grow more demanding.

The Vivo Y31 Pro 5G is the clear winner in this category. The combination of a newer process node, stronger benchmark results, faster RAM, higher GPU clocks, and greater maximum memory capacity adds up to a device that is more capable today and better positioned for the future. The A17 5G is no slouch for general daily use, but users who care about performance — whether for gaming, multitasking, or simply keeping their phone feeling fast over time — will find the Y31 Pro 5G the more capable choice.

Both phones share a 50 MP primary sensor, but the camera systems diverge in meaningful ways from there. The Samsung Galaxy A17 5G fields a triple rear camera — adding a 5 MP and a 2 MP lens — while the Vivo Y31 Pro 5G makes do with a dual setup pairing its main sensor with only a 2 MP auxiliary lens. More importantly, the A17 5G includes optical image stabilization (OIS), which the Y31 Pro 5G lacks entirely. OIS is one of the most impactful real-world camera features, physically compensating for hand shake to produce sharper photos in low light and steadier handheld video — advantages that software stabilization cannot fully replicate. The A17 5G also leads on selfies, with a 13 MP front camera versus the Y31 Pro 5G's 8 MP, a noticeable gap for users who prioritize self-portraits or video calls.

The Vivo punches back decisively in video recording. Its main camera captures footage at 4K (2160p) at 30 fps, while the A17 5G tops out at 1080p at 30 fps — a significant ceiling difference for anyone who wants to shoot high-resolution video, crop footage in post, or future-proof their clips. The Y31 Pro 5G also carries two flash LEDs versus one on the A17 5G, which can produce more even and natural-looking flash illumination in dark environments.

This category produces a genuine split depending on use case. The Galaxy A17 5G is the stronger choice for photo-focused users: OIS meaningfully improves image quality in challenging conditions, the extra rear lens adds versatility, and the higher-resolution front camera is a clear win. The Vivo Y31 Pro 5G, however, holds the advantage for video creators — 4K recording is a capability the A17 5G simply cannot match. On balance, for mixed photo and video use, the A17 5G's OIS is the more broadly useful differentiator, but videographers should weigh the Y31 Pro 5G's 4K capability heavily.

Rarely does a spec group produce a result this definitive: based on the provided data, the Samsung Galaxy A17 5G and the Vivo Y31 Pro 5G are in complete parity on operating system features. Both ship with Android 15 and share an identical feature set across every tracked specification — from privacy controls like location and camera/microphone permissions, to productivity tools like split-screen multitasking, Picture-in-Picture, and widgets, to quality-of-life additions like dark mode, dynamic theming, and an extra dim mode.

The shared privacy profile is worth noting: both phones support app tracking controls, clipboard warnings, and on-device machine learning, reflecting Android 15's mature privacy framework. Neither device, however, gets direct OS updates — meaning both rely on their respective manufacturers (Samsung and Vivo) to push Android updates, which can introduce delays compared to devices that receive updates straight from Google. This is a shared limitation rather than a differentiator, but it is relevant for users who prioritize timely security patches.

This category is an unambiguous tie. There is not a single feature in the provided data set that one phone offers and the other does not. Users choosing between these two devices should look to other specification groups — performance, display, cameras, or design — to inform their decision, as the software experience, at least as defined by these specs, will be functionally identical.

Battery is one of the starkest contrasts between these two phones. The Vivo Y31 Pro 5G packs a 6500 mAh cell against the Samsung Galaxy A17 5G's 5000 mAh — a 30% larger reserve that, all else being equal, translates directly into more hours of screen-on time before needing a charge. For heavy users, travelers, or anyone who regularly goes a full day and into the evening, that extra capacity is a meaningful real-world cushion against reaching for a charger.

The charging speed gap compounds the advantage. The Y31 Pro 5G supports 44W fast charging compared to 25W on the A17 5G. Not only does the Vivo start with a larger tank, it refills it considerably faster — a combination that gives it a decisive edge in both endurance and recovery time. Neither phone supports wireless or reverse wireless charging, so the wired charging speeds are the only relevant differentiator beyond raw capacity.

The Vivo Y31 Pro 5G wins this category outright, and it is not particularly close. A bigger battery that also charges faster leaves the Galaxy A17 5G with no offsetting advantage in this group. Users who prioritize battery life and charging convenience — which, for most people, is a daily concern — will find the Y31 Pro 5G the considerably stronger option here.

Audio is a short but clear-cut comparison. Both phones drop the 3.5 mm headphone jack and neither supports advanced Bluetooth codecs like aptX or LDAC, meaning wired and high-fidelity wireless audio options are equally limited on each device. The single differentiator in this group is speaker configuration: the Vivo Y31 Pro 5G has stereo speakers, while the Samsung Galaxy A17 5G does not.

Stereo speakers matter more than they might appear on a spec sheet. A single mono speaker pushes sound in one direction, which can feel thin and positional during media playback. Stereo speakers create a wider soundstage — music, video dialogue, and game audio all feel more spatially immersive. The difference is especially noticeable when watching videos in landscape orientation, where dual speakers can fire from both ends of the phone to create a genuine left-right separation that a mono setup cannot replicate.

The Vivo Y31 Pro 5G takes this category by virtue of being the only one of the two with stereo speakers. For users who regularly consume media or play games without headphones, this is a tangible everyday advantage. The Galaxy A17 5G offers no compensating audio feature based on the provided data, making this a straightforward win for the Vivo.

Connectivity tells a tale of meaningful trade-offs. The most impactful single difference is NFC: the Samsung Galaxy A17 5G has it, the Vivo Y31 Pro 5G does not. For most users, NFC is synonymous with contactless payments — tap-to-pay at terminals, public transit gates, and peer-to-peer transfers all depend on it. Its absence on the Y31 Pro 5G is a genuine daily inconvenience for anyone who has moved away from physical cards. In the other direction, the Y31 Pro 5G includes an infrared sensor, which the A17 5G lacks, allowing it to function as a universal remote for TVs and home appliances — a niche but genuinely useful feature for some users.

On cellular throughput, the Y31 Pro 5G pulls ahead with a peak download speed of 3270 Mbits/s and a symmetrical upload speed of 3270 Mbits/s, compared to the A17 5G's 2550 Mbits/s down and 1280 Mbits/s up. The upload gap is particularly notable — more than double — which benefits users who frequently send large files, stream live video, or work in upload-heavy workflows. The Y31 Pro 5G also has a marginally newer Bluetooth 5.4 versus 5.3 on the A17 5G, though this difference is unlikely to be perceptible in everyday use. Both phones share the same Wi-Fi standards (Wi-Fi 5), dual SIM support, USB-C, expandable storage, and a full sensor suite including GPS, gyroscope, and compass.

Neither phone dominates this category cleanly — it comes down to which features matter most to the individual user. The Galaxy A17 5G holds the edge for anyone who relies on NFC for payments, which describes the majority of users in markets where contactless payments are mainstream. The Y31 Pro 5G counters with stronger cellular speeds, especially on upload, and the bonus of an infrared sensor. On balance, NFC's everyday utility gives the A17 5G a slight overall edge here, but users who do not use tap-to-pay will find the Vivo's connectivity profile equally compelling.

The Miscellaneous group is the second category in this comparison to produce a complete tie. The Samsung Galaxy A17 5G and the Vivo Y31 Pro 5G are identical across every tracked spec here: both include a video light, and neither features a sapphire glass display, a curved display, or an e-paper display.

This is a definitive tie, and with so few differentiating data points available, there is simply nothing in this group to separate the two devices. Users should rely entirely on the other specification groups — particularly performance, battery, cameras, and display — to inform their decision between these two phones.
