| 2-minute Review [Positives] |
- Stunning looks, similar rainbow-like effects at the back as the Galaxy A50s when caught against the light, and a prism-like pattern that Samsung calls a “3D prism design” - it's a head-turner no doubt
- While it supports a polycarbonate back, it still manages to look premium
- The front looks stylish and modern too with a single punch-hole in the upper middle of the display
- Compact and light for the display size and battery capacity, at just 172g, and 7.9mm in thickness
- Bright, large 6.5-inches Super AMOLED panel with a full-HD+ resolution - its punchy colours make it a joy to stream content, while games also look great on the panel because of its high colour accuracy
- There's Widevine L1 support by default, which makes streaming content in HD possible
- Comes with Android 10 out of the box - Samsung's One UI 2 is now one of the better, more clean and streamlined Android UIs around, and is well optimised for modern large displays (like this one)
- Samsung has also added some neat features including a Game Booster and an intuitive gesture-based navigation system
- Decent performance with the same Exynos 9611 processor as the Galaxy A50s (similar to Qualcomm Snapdragon 660/665) - the experience is fairly smooth throughout with games like PUBG Mobile and Asphalt 9
- Decent quad camera setup at the back - a 48MP primary sensor + 12MP wide-angle camera + 5MP macro camera + 5MP depth sensor
- Under good light, the Galaxy A51's primary camera managed to capture detailed shots with good dynamic range - images are reasonably sharp, noise is also competently removed, colours are generally nice, and the phone strikes a good balance with saturation
- The ultra wide-angle cam is a significant upgrade from the one on the A50s, and it offers improved sharpness and detail - dynamic range is also substantially better, making for an altogether pretty capable ultra-wide camera as far as mid-rangers go
- Macro camera turns out quite good close ups - you can get a lot closer to your subject when using the macro camera and the sensor picks up a fair bit of detail
- Very good portrait mode ("Live focus") - image quality is good and the depth camera helps the Galaxy A51 do a decent job of edge detection
- The front 32MP camera is decent and produces nice colours, the detail is quite good as far as selfie cameras go - portrait selfie mode is decent too
- Decent video recording from both primary and wide cameras with dedicated 'super steady' mode which allows you to shoot decent “action” videos (though stabilisation is not available at 4K)
- Decent bottom-firing speaker - sufficient for personal listening
- Solid, dependent battery life from the 4000 mah battery - will easily manage to get a day and a half's worth of regular use
- Reasonable 15W fast charging - charges 67 percent in an hour (though, not as quick as others in this segment such as the Redmi K20 Pro)
- Overall, a decent and likeable smartphone from Samsung - offers a polished experience, a slim and light body, solid battery life, a crisp display, and of course the Samsung brand (though, the performance at this price is a letdown)
|
- Xiaomi has gone big on the design front this time - the Redmi K20 Pro has a glass back with one of the most evocative gradient patterns you'll come across on any phone today - it's both premium to feel, and stunning to look at
- The gradient effect that kicks in under the right lighting condition is quite mesmerising
- The front is modern and sharp too, with a 'full screen' notch-less display (the selfie camera is a 'popup' one)
- Decent in-screen fingerprint sensor - reasonably quick and reliable
- Gorgeous, 6.39-inch Super AMOLED display - easily one of the best panels you'll find in this price segment - it has vibrant colors and excellent contrast levels, and sunlight readability is great as well
- Of course, the lack of a cutout means you get an all-screen front, and the minimal bezels at the top and bottom create an immersive experience when playing games or viewing videos on the device
- MIUI, especially with it's recent improvements continues to one of the better, more cohesive custom Android UIs around - and it's packed with features like gesture navigation, anti-flicker mode, reading mode, second space, dual apps, themes, etc
- The K20 Pro also adds the POCO Launcher on top of MIUI - which brings the Dark Mode and App drawer to the K20 Pro
- Xiaomi is also rolling out a Game Turbo feature that prioritizes bandwidth and mutes incoming notifications when you're in a game
- Top-notch flagship performance with the top-notch Snapdragon 855 chipset at the core - the K20 Pro is expectedly a performance beast - and gets the highest Antutu scores of any Android phone at the moment
- Very good triple rear camera setup - the phone has a 48MP primary camera backed by an 8MP telephoto lens and a 13MP wide-angle shooter
- Image quality is great in all sorts of lighting conditions - they look crisp, vibrant, and details are captured well
- The ultra-wide sensor and 2x telephoto lens also produce generally good results
- The K20 Pro also comes with a dedicated night mode that does the usual multi-frame processing, and the results are pretty good - it gets more light in, and makes things sharper
- Decent 20MP popup selfie camera, with a good portrait mode
- Overall, the rear camera setup on the K20 Pro is the best for this price bracket, and matches up well to more expensive phones like the OnePlus 7 and Asus 6Z
- Has a 3.5mm jack, that a lot of flagships these days tend to skimp on
- Loud (single) downward firing speaker
- Very good battery life with a 4000mAH battery - combine that with a very efficient 855 processor, and you will comfortably get 1.5 days of use
- Fast charging support - up to a cool 27W (a 27W capacity charger will however need to be purchased separately for super fast charging - that said, Xiaomi does include a still-very-fast 18W charger in the box)
- Xiaomi has again hit the ball out of the park with the Redmi K20 Pro, providing a still-excellent-value successor to the super successful Poco F1 - this is the cheapest price point at which you will get the flagship Snapdragon 855, along with all the latest features of 2019 - full screen, popup selfie camera, and in-display fingerprint sensor - people who attach more value to the software experience though might still want to spend a little more and go for the OnePlus 7 or Asus 6Z, for a cleaner experience

| 2-minute Review [Negatives] |
- The in-display fingerprint sensor as well as the facial recognition are on the slower side
- The glossy body is prone to picking up fingerprints
- There's still some bloatware pre-installed, including third-party apps and some of Samsung's own apps such as Samsung Shop (though most of them can be uninstalled)
- At this price, the performance feels weak - there are cheaper phones that offer much better performance, like the Redmi K20 & the Realme X2
- Low light photos out of the Galaxy A51 aren't great (from all cameras) - The output is soft and noisy, while the colours are relatively desaturated
- Overall, while the Galaxy A51 offers good cameras, there are certainly better options available, such as the Redmi K20 Pro
- However, as far the value for money goes, the Galaxy A51 is far behind from the competition - there are better options like the Redmi K20 Pro which gets you a flagship-grade processor, an HDR display, more premium materials, and even better cameras - in fact, for a bit less money, you could also get the Redmi K20, which is also very capable
|
- Face unlock mechanism is a little clunky - you have to first wake the screen and swipe up for the camera module to engage (this might get sorted via a software update though)
- One issue with MIUI in recent times is the ads in the interface & notifications - those are still there (though a little less intrusive) - and while there are ways to disable them, it's a technical solution that a lot of prospective buyers will not be aware of
