2-minute Review [Positives]
  • Looks slick, and reflects off the same iridescent rainbow-like effects at the back as the Samsung Galaxy A50 when caught against light, only this one, comes with a prism-like pattern that Samsung calls a “3D prism design” - it's a head-turner no doubt
  • And while the Samsung Galaxy A50s bears a polycarbonate body, it doesn’t look cheap and sports a very premium “glassy” look overall
  • On the front is a sharp, modern panel with slim-bezels, and a U-shaped notch design (similar to Galaxy A50)
  • Facial recognition to unlock your phone works well
  • Beautiful 6.4-inch Full HD+ Infinity-U Super AMOLED display with a high 91.6% screen-to-body ratio, and Corning Gorilla Glass 3 for protection
  • The screen looks sharp and bright, and being an AMOLED display, you will get deep black and vivid colors - sunlight legibility is also pretty good
  • Samsung's One UI 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 a Game Booster tool to the A50s to offer a better gaming experience
  • Other features include an intuitive gesture-based navigation system, and an option to wake up Bixby using the power button
  • Solid mid-range performance with the robust Samsung Exynos 9611 SoC (similar to Snapdragon 660 and Exynos 9610) - the experience is pleasant and smooth throughout including with games like PUBG Mobile and Asphalt 9
  • Good thermal management too - the phone doesn't warm up quickly despite extended game play
  • Decent set of triple rear cameras for the price bracket - a 48MP primary camera with an f/2.0 aperture
  • a second 5MP depth camera with f/2.2 aperture, and a third 8MP ultra-wide lens
  • The quality of the pictures from the primary camera is quite good during daylight and outdoors - the A50s handles high-contrast scenes well and adds the right amount of detail and vibrance
  • Night mode works reasonably ok for low-light situations and doesn’t add unnatural exposure to the scene
  • Portrait mode ("Live focus") works well too especially when capturing outdoor daylight scenes
  • Decent video recording performance with a dedicated 'super steady' mode which allows you to shoot decent “action” videos
  • Decent 32MP selfie camera - in daylight outdoor lighting, selfies clicked turn out quite clear (not so much is low-light though)
  • Overall, this is a fairly good camera setup for this price bracket (though not quite up to the level of the category leaders)
  • Very good battery life with a 4000mAh battery - you will get about 1.5 days of use
  • 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)
2-minute Review [Negatives]
  • The fingerprint sensor that sits beneath the display, is a tad bit slow
  • The phone is a smudge-magnet, relatively easy to scratch, and also slippery (so you will want to use a case)
  • This is however not the best performing phone in this price bracket - you will get better CPUs and stronger performance from Xiaomi and Realme phones
  • The camera app is a little bit slow to launch and there is a small shutter lag when capturing photos
  • As is right now the case with most mid-range phones, the wide-angle camera’s photos look fairly distorted, and details are soft
  • Low light performance could have been better, across the board
  • Volume levels of the speaker are a bit on the low side and could have been better - it's a little difficult to hear audio outdoors in a noisy environment
  • Although the phone supports 15W fast charging, but it only includes a 10W standard (non fast) charger - it takes over 3 hours for A50s to go from 0% to 100%
  • On the whole, the A50s, while a pretty decent phone by itself, will find the competition much more intense (than what its predecessor A50 faced) - unless you are a Samsung loyalist, you will want to look at the competition especially from the likes of Realme and Xiaomi
  • 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
