Buying a phone is a decision you live with every day, so this page explains what the Y31d offers, where it is limited, how it works on Kenyan networks, what the 6GB RAM + 256GB configuration means for you, and how to check the phone on delivery. We say plainly when a detail is not confirmed and we confirm it with you before you pay.

Key specs at a glance

Specifications come from published manufacturer and retail specification sheets. Phones sold in different markets can differ in model number, network bands, pre-installed apps and warranty, so please ask our team to confirm the exact model number, colour and warranty of the phone you order before you pay.

What's in the box

The box contents are not listed in the sources we read. Phones are often sold with a USB cable and a SIM tool, and many brands no longer include a charger, so we confirm exactly what is in the box for your unit before you pay.

Overview: who the Y31d is for

The Vivo Y31d is a mid-range 4G phone built for endurance: a 7,200 mAh battery, 44W charging, IP68 and IP69 protection and a 120 Hz screen.

The 6GB RAM and 256GB storage version is the larger of the two listed. 256GB gives comfortable room for apps, photos and downloaded video for several years, which matters because there is no card slot.

This is a 4G phone, so check that 5G is not a must-have for you.

Display

The Y31d has a 6.75-inch IPS LCD display with a resolution of 720 x 1570 pixels, a 120 Hz refresh rate, and 1250 nits of peak brightness. On that size and resolution, the pixel density works out to about 256 pixels per inch, from our calculation. That is acceptable for everyday use, though fine text will look a little softer than on a higher-resolution screen if you hold the phone close. A 120 Hz refresh rate means the screen redraws 120 times a second, which makes scrolling through social media, menus and web pages feel smoother than on a standard 60 Hz screen. If you want the background, read our guide on refresh rate explained.

The 6.75-inch IPS LCD has an HD+ resolution of 720 x 1570 pixels and a 120 Hz refresh rate, with up to 1,250 nits peak brightness. A 120 Hz refresh rate makes scrolling feel smoother, and the very high peak brightness helps in strong Kenyan sun. The resolution is modest, so fine text looks a little softer than on a Full HD screen.

A phone screen in Kenya has to cope with strong sunlight, so brightness matters more than many buyers realise. Peak brightness figures describe the best case on a small part of the screen, not what you see all day. Try the screen outdoors before you buy if you can, and keep the brightness on auto. A tempered-glass screen protector is a cheap way to protect the glass from keys and coins in a pocket.

Performance

The Y31d uses the Qualcomm Snapdragon 6s 4G Gen 2 (6 nm). The published specifications list an octa-core CPU with four 2.9 GHz Cortex-A73 cores and four 1.9 GHz Cortex-A53 cores. The graphics are handled by the Adreno GPU (model not named in the source we read). The Snapdragon 6s 4G Gen 2 is a capable entry-to-mid-range chip. It handles calls, WhatsApp, social media, browsing and video well and runs mid-weight games. With 6GB of RAM, multitasking is comfortable.

For everyday use, such as WhatsApp, Facebook, TikTok, YouTube, banking apps and M-Pesa, the Y31d should be adequate. Where the limits show up is in the heaviest games at high settings and long editing sessions. We have not run benchmark tests on this phone and we do not quote benchmark scores, since published numbers vary by test.

Memory and storage: what 6GB RAM + 256GB means

This version has 6GB of RAM and 256GB of storage. RAM is the phone's short-term working memory, and 6GB is a comfortable amount of RAM for most users. Switching between several apps, keeping a browser with many tabs open and running mid-weight games should feel smoother than on 4GB.

Storage is where your apps, photos, videos, music and downloaded files live. Part of the 256GB is taken by the operating system and pre-installed apps, so the space you can actually use is less than the number on the box. As a guide from our experience, 256GB or more gives comfortable room for apps, photos and downloaded video for several years. WhatsApp alone can use many gigabytes if you are in busy groups that share videos and voice notes, so switch off auto-download for media you do not need.

The sources we read do not list a memory-card slot for this phone, so treat the built-in storage as the storage you keep and choose the size with that in mind.

Cameras

The Y31d has a 50 MP main camera with an auxiliary lens and an 8 MP front camera. A 50 MP sensor gives more detail in good light than the 13 MP cameras on cheaper phones. Video goes up to 1080p at 30 fps on both cameras, not 4K.

Rear camera: a 50 MP f/2.0 main camera with phase-detection autofocus and an auxiliary lens, with an LED flash. Front camera: an 8 MP f/2.1 camera. Video: up to 1080p at 30 frames per second on both cameras.

Camera quality depends heavily on light, a clean lens and a steady hand. Wipe the lens with a soft cloth before shooting, because pocket grease is the most common cause of hazy photos. Megapixel numbers do not tell the whole story: a higher number does not automatically mean a better photo, and processing matters as much as the sensor. For video calls and social media clips, the phone should be fine; for serious photography, ask us to show you sample shots in the shop.

Battery and charging

The Y31d has a 7200 mAh battery and supports 44W wired charging. A 7,200 mAh silicon-carbon battery is among the largest on any phone at this price and should last well beyond a full day of normal use. 44W charging is fast for this class: the listing quotes 50% in about 43 minutes under its test conditions. The phone also lists reverse wired charging and bypass charging for gaming. As a rough guide from our own calculation, a 7200 mAh battery stores about 28 Wh of energy. At 44W, the theoretical minimum for a full charge is about 38 minutes, and in real life charging slows as the battery fills, so expect noticeably longer, especially with a lower-power adapter. The published specifications list 44W wired charging. A box charger matching that rating is needed to reach the quoted speed. The published specifications do not say what is in the box, so we confirm whether a charger is included before you pay.

Kenya has power cuts, so a phone that lasts a full day matters. To make the battery last: lower the screen brightness, switch off background refresh for apps you do not need, use Wi-Fi at home to save mobile data and power, and avoid leaving the phone in a hot place. A power bank is a sensible backup. Use a charger and cable from a trusted source, because cheap chargers can charge slowly or damage the battery over time. Remember that mains sockets in Kenya are Type G, so check the plug on any charger you buy.

Software and updates

The phone runs Android 16 with OriginOS 6. The published specifications make no update promise, so we do not state one. Check Settings > Software update after setup.

Software support matters more than most buyers realise. A phone that keeps receiving security updates stays safer for banking, M-Pesa and email for longer. Check Settings > Software update after you set the phone up, and install updates over Wi-Fi.

Connectivity: SIM, networks and M-Pesa

The Y31d is 4G LTE (no 5G). It supports dual nano-SIM. The published specifications list 4G LTE and HSPA, and no 5G. The exact band list is not given in the source we read, so we check the bands of your unit against the networks you use before you pay. No memory-card slot is listed, so the storage is fixed and the size you buy is the size you keep.

M-Pesa and dual SIM. With a physical SIM, M-Pesa works through the SIM Toolkit on the Safaricom line, and many Kenyans use two SIMs, for example Safaricom for M-Pesa and Airtel for data bundles. Check which slot is set for mobile data and calls in Settings so you do not burn through the wrong bundle.

Wi-Fi and Bluetooth. Wi-Fi is 802.11 a/b/g/n/ac dual-band and Bluetooth is version 5.1. The phone also lists GPS and an infrared port. NFC is not listed, so do not expect tap-to-pay or tap-to-pair features. The sources do not list a 3.5mm headphone jack, so you will need a USB-C or wireless headset.

5G in Kenya. This phone does not have 5G, so it will use 4G LTE, which is widely available across Kenya. For most everyday use, 4G is fast enough for WhatsApp, YouTube and video calls.

Design, build and durability

The Y31d measures 166.6 x 78.4 x 8.4 mm and weighs 219 g, with a glass front and a plastic frame and back. It is rated IP68 and IP69, which means dust-tight, immersion in water and protection against high-pressure, high-temperature water jets in lab conditions. That is a rare level of protection at this price. Liquid damage is normally not covered by a warranty.

The phone carries an IP68 and IP69 rating. IP ratings describe lab conditions, so treat it as protection against splashes and dust, not a reason to take the phone swimming. Liquid damage is not normally covered by a warranty. A fingerprint sensor is on the side of the phone, so you can unlock without typing a PIN.

Looking after your phone in Kenya

Dust, heat and rough handling are the usual enemies. Keep the phone out of direct sun on the dashboard, avoid charging under a pillow, and clean the charging port gently with a dry soft brush if dust builds up. Use a case with raised edges to protect the screen and corners, and a tempered-glass protector for the display. Do not charge with a damaged cable. If the phone gets wet, switch it off, dry the outside and do not charge it until it has had time to dry. In a crowded place such as a matatu stage or the CBD, keep the phone out of sight and out of reach of snatchers, and note down your IMEI (dial *#06#) so you can report a loss.

Accessories worth buying with the Y31d

• A tempered-glass screen protector and a case matched to the model.
• A fast charger and cable if none is in the box. Ask us which wattage suits this phone.
• A power bank for long days and power cuts.
• Earphones or a headset. This phone has no headphone jack in the sources we read, so choose USB-C or Bluetooth earphones.
• A memory card (only if your model supports one), from a trusted brand.
• A surge protector for charging at home.

Ask our sales team on 0745 575 931 and we will quote accessories together with the phone.

Warranty and stock

Warranty depends on the market version of the phone and on who stocks it. We confirm the market version, the model number and the exact warranty terms in writing for the specific unit before you pay, and Customer Relations on 0794 488 806 handles warranty questions after purchase. Keep your receipt and the box.

How to check your phone when it is delivered

1. Inspect the box for damage before you sign, and check that the seal is intact.
2. Check that the model number, serial number and IMEI on the box match the phone (dial *#06# for the IMEI) and note them on your receipt.
3. Check the box contents against what we confirmed with you.
4. Switch the phone on and test the screen, touch response, speakers, microphone, both cameras, fingerprint sensor, charging port and SIM slots.
5. Check that the phone is not locked to another account and that no previous owner has set it up.
6. Contact our Customer Relations team on 0794 488 806 straight away if anything is wrong.

How to avoid a fake or a misdescribed phone

Phone fraud takes several forms: clone phones that copy a famous design, used phones sold as new, and phones with a different RAM or storage from what was advertised.

• Check the specs on the phone itself. In Settings > About phone, check the model number, RAM and storage match this page.
• Check the IMEI. It should be the same on the box, under the battery cover or SIM tray area where applicable, and in the phone. A missing or mismatched IMEI is a warning.
• Look at the packaging and seal. Reprinted boxes, loose seals and missing labels are warning signs.
• Watch for the price. A price far below the market is a reason to ask why.
• Buy from a seller with an address. Choose a seller who gives a receipt and explains the warranty, and avoid paying a stranger before you have seen the phone.
