Introduction of Samsung Galaxy J7 Duo
This review dives into the design, display, performance, camera experience, battery life, software and connectivity of the Samsung Galaxy J7 Duo, then gives a practical verdict for everyday users in the UAE. I'll highlight real-world pros and cons so you can decide whether the J7 Duo is right for your daily needs — calling, browsing, social media, light photography and occasional media streaming. Key factual specs used in this review are sourced from Samsung’s launch notes and established device databases.
Design & build — simple, familiar Samsung feel
The Galaxy J7 Duo follows Samsung’s classic all-metal look from that era: rounded edges, a front fingerprint sensor integrated into the home button, and a practical weight that feels solid in the hand. It’s not trying to be flashy — the focus is durability and ergonomics. The phone measures roughly 153.5 × 77.2 × 8.2 mm and weighs around 174 g, which makes it comfortable for one-hand use for most people. Build quality is decent for its price class, but there’s no water resistance or premium glass finish to expect.
Display — Super AMOLED still shines
One of the J7 Duo’s strongest assets is its 5.5-inch Super AMOLED HD (720×1280) screen. While the resolution isn’t high by modern flagship standards, the Super AMOLED panel delivers punchy colours, excellent contrast and deep blacks — making social feeds, videos and everyday apps look nicer than what many LCDs at this price used to offer. The pixel density (~267 ppi) is acceptable for typical day-to-day use (web browsing, messaging, video streaming). If you value saturated colours and good outdoor visibility at moderate brightness, the J7 Duo’s display remains a pleasant surprise for a budget device.
Performance — reliable for everyday tasks
Under the hood the J7 Duo ships with a Samsung Exynos mid-range chipset (Exynos 7885 variants in some markets) paired with 3 GB RAM and 32 GB storage (expandable via microSD). This configuration handles everyday workloads — WhatsApp, Instagram, YouTube, web browsing, light multitasking — smoothly. Heavier modern games and very large multitasking loads will expose limits: expect occasional frame drops in demanding 3D titles and a need to close apps for optimal memory. For typical UAE users who use phones mainly for communication, social media and media playback, performance is solid and dependable.
Cameras — dual rear setup focused on portraits
The J7 Duo’s headline camera feature is its dual rear camera: a 13 MP main sensor paired with a 5 MP depth sensor to enable live bokeh/portrait effects. The rear cameras perform well in good light — sharp, detailed shots with natural colours and the Samsung colour tuning most users prefer. Low-light performance is limited: noise rises when light drops and the camera’s night capability can’t match newer phones with larger sensors or multi-frame processing. The 8 MP front camera produces friendly, well-lit selfies in daylight and supports the phone’s built-in beautification and portrait modes. For casual social photos and portrait snaps the J7 Duo still delivers satisfying results.
Battery life & charging — day-long with realistic usage
The 3,000 mAh battery paired with the efficient AMOLED screen and mid-range chipset typically returns a full day of mixed use (calls, messaging, some social media, low-to-moderate screen-on time). If you are a heavy user (long gaming sessions, lots of video streaming or GPS navigation), you’ll likely need a top-up before bedtime. The phone uses standard micro-USB charging (no fast-charging standards found on the original spec), so plan for longer charge times than modern USB-C fast-charge phones. For everyday commuting and light-to-moderate usage patterns common in the UAE, battery life is acceptable.
Software & updates — Android experience and longevity
The J7 Duo launched with Android 8.0 Oreo and Samsung’s Experience UI. In some markets it has received later maintenance updates and limited Android 9/10/One UI updates historically, but it is not a candidate for ongoing major OS updates today. If receiving the latest Android features and security patches long-term is crucial for you, consider a newer device; however, for everyday users who prioritize stable apps and a familiar Samsung UI, the J7 Duo’s software remains serviceable. (Check the specific unit you buy for its current OS build and update status — refurbished or new-old-stock units may ship with different software.
Connectivity & extras
The phone supports 4G LTE, Wi-Fi, Bluetooth, GPS and a headphone jack — all the essentials for daily life. There’s a dedicated microSD slot (so you don’t lose a SIM slot when expanding storage) and a rear fingerprint sensor for quick unlocking and basic security. You won’t find NFC widely on every variant, and the port is micro-USB, not USB-C. Overall the connectivity package is practical and covers usual UAE needs like mobile internet, navigation and media streaming.
Availability & pricing in UAE — what to expect
Because the J7 Duo is an older 2018 model, it’s often sold today as new-old-stock, pre-owned or refurbished through UAE retailers and online marketplaces. Listings and historical retail prices vary — some retailers have listed J7 models in the AED 700–900 range during stock clearance or special offers, but availability fluctuates and pricing depends on condition and seller. If you’re buying in the UAE, compare options from established electronics retailers and certified refurbishers to ensure warranty and return options.
Who should buy the Galaxy J7 Duo in 2025 (practical verdict)
Buy the J7 Duo if:
-
You want a budget phone with a Super AMOLED screen and comfortable one-hand use.
-
You need a phone for calls, messaging, social apps, streaming and occasional photos.
-
You’re comfortable buying refurbished / clearance stock to get more value for money.
Don’t buy the J7 Duo if:
-
You require the latest Android updates, advanced low-light photography, or fast charging / USB-C.
-
You’re a heavy mobile gamer or power user who needs sustained high-performance.
Overall: for everyday users who prioritise display quality, solid battery life and a simple camera portrait feature without paying flagship prices, the Galaxy J7 Duo remains a sensible, pragmatic choice — especially in markets like the UAE where it can be a budget-friendly find.
Tips for buying in the UAE
-
Check the variant and IMEI — Exynos variants and RAM/storage differ by region. Confirm the model number (SM-J720x) and RAM 3 GB.
-
Prefer warranty or certified refurbishers — older phones can have battery wear; a seller warranty is valuable.
-
Inspect charging port & battery health if buying used — micro-USB ports can be loose after much use.
-
Buy extra storage if needed — a microSD card is a cheap way to fix low internal storage for photos and videos.
Conclusion of Samsung Galaxy J7 Duo
The Samsung Galaxy J7 Duo is a thoughtful, no-nonsense smartphone for everyday needs: an attractive Super AMOLED screen, straightforward performance for daily apps, and a dual-camera system tuned for portrait shots. It isn’t cutting-edge by today’s standards, but in the UAE market — where it turns up as new-old-stock or refurbished — it’s a practical value option for users who want dependable basics without the premium price. If you prioritize long-term software updates, very fast charging or top-tier low-light photography, look to more recent models; otherwise, the J7 Duo still delivers what most everyday users need.
FAQs of Samsung Galaxy J7 Duo

Q.4. Will this phone receive Android updates today?
The J7 Duo launched with Android 8.0 and received limited subsequent updates historically, but it is not on the list for modern Android major updates now. Expect only limited or no further OS upgrades. Check the specific unit’s build before purchase.
Q.5. Where can I buy the J7 Duo in the UAE and approx. price?
You can sometimes find the J7 Duo as new-old-stock, refurbished or used units on UAE retail sites and marketplaces.
