The vivo Y31 5G is the stronger paper choice for battery capacity and charging speed; the Samsung Galaxy A27 5G lists a sharper AMOLED display, a higher-tier processor, and a more versatile rear-camera setup. A direct price difference cannot be established from the available listings because they are for different countries and configurations.
How the two phones compare on paper
The figures below come from regional manufacturer sources, not a same-market test. Vivo also notes that specifications can vary by region or production batch, so confirm the exact local model before buying.
| Specification | vivo Y31 5G | Samsung Galaxy A27 5G |
|---|---|---|
| Processor | Snapdragon 4 Gen 2 (vivo UAE specifications) | Snapdragon 6 Gen 3 (Samsung global specifications) |
| Display | 6.68-inch LCD, 1608 × 720, up to 120Hz (vivo UAE specifications) | 6.7-inch FHD+ Super AMOLED, up to 120Hz (Samsung global specifications) |
| Battery and charging | 6500mAh typical battery; 44W charging (vivo UAE specifications) | 5000mAh typical battery; 25W charging (Samsung global specifications) |
| Rear cameras | 50MP + 0.08MP (vivo UAE specifications) | 50MP wide with OIS, 5MP ultrawide, and 2MP macro (Samsung global specifications) |
| Front camera | 8MP (vivo UAE specifications) | 12MP (Samsung global specifications) |
| Operating system on cited product page | Android 15 with Funtouch OS 15 (vivo UAE specifications) | Android 16 with One UI 8.5 (Samsung global specifications) |
| Water and dust rating listed | IP68, IP69, IP69+ (vivo UAE specifications) | IP64 (Samsung global specifications) |
These are published specifications, not comparative test results. They do not establish real-world speed, battery runtime, charging time, camera quality, display brightness, color accuracy, or outdoor visibility.

Display: Samsung lists the sharper panel
Both cited specifications list refresh rates up to 120Hz, but the panel types and resolutions differ. Samsung specifies a 6.7-inch FHD+ Super AMOLED screen; vivo specifies a 6.68-inch LCD at 1608 × 720. On listed resolution and panel type, the Galaxy A27 5G has the clearer advantage. The specifications alone do not show how either screen performs in particular lighting conditions.

Battery and charging: vivo has the larger figures
Vivo lists a 6500mAh typical battery and 44W charging, compared with Samsung’s 5000mAh typical battery and 25W charging. Those figures favor the Y31 5G for stated capacity and charging wattage, but they do not predict a measured runtime or time to recharge; no comparative battery or charging test is established here.
Processor and cameras: what the spec sheets establish
Processor
The Y31 5G’s cited UAE specification names the Snapdragon 4 Gen 2, while Samsung’s global specification names the Snapdragon 6 Gen 3. The listed chip tiers favor the Galaxy A27 5G on paper, but without benchmark or gaming results, they do not quantify a performance difference.

Rear and front cameras
Samsung lists a 50MP main camera with optical image stabilization (OIS), plus 5MP ultrawide and 2MP macro cameras. Vivo lists a 50MP and 0.08MP rear setup. The Samsung specification therefore describes more camera roles and explicitly includes OIS; megapixel counts and component lists alone do not determine photo or video quality.
For selfies, the listed resolutions are 12MP on the Galaxy A27 5G and 8MP on the Y31 5G. These are resolution specifications, not a comparison of image quality.

Water and dust ratings are not damage-proof guarantees
The cited vivo UAE page lists IP68, IP69, and IP69+, while Samsung’s global page lists IP64. These are manufacturer-listed ingress-protection ratings; they should not be read as a promise that a phone is immune to damage. Check the local product documentation for the applicable rating and its conditions, and do not infer identical protection from different rating labels.
Price difference: the available listings are not comparable
The prices below are from separate markets and do not establish which phone costs less in the same country or a meaningful price gap.

| Phone and market | Published price and configuration | Source and qualification |
|---|---|---|
| vivo Y31 5G, India | ₹19,999 for 4GB/128GB; ₹27,999 for 6GB/128GB | vivo India online store; retrieved in 2026, live listing prices that may change |

Do not subtract or convert these figures into a claimed price difference: the listings are from different countries, and the Samsung starting-price configuration is not specified here as a directly matching variant. For a useful comparison, check both phones’ current prices for the same country and the exact memory and storage configuration you would buy.
