2-minute Review [Positives]
  • Excellent, premium, 'dreamy' new design, with high quality materials and top-notch build quality - the frosted glass at the back just adds a new dimension to not just the visual appeal but also the in-hand feel
  • The front has a smaller teardrop notch than the OnePlus 7
  • A bit smaller than the OnePlus 7 Pro and slightly easier to hold (it's still on the large side though on absolute scale, so if you don't like big phones, you might want to reconsider)
  • Basic water resistance (though it's not IP rated)
  • Snappy in-display fingerprint scanner
  • Gorgeous, super smooth 90Hz AMOLED display - along with the display on the OnePlus 7 Pro, this is one of the most amazing displays out there on any smartphone - you will enjoy how much zippier and smoother the phone feels scrolling through things like web pages and apps
  • Strong brightness and great sunlight legibility
  • This time it's also a flat screen without the curved edges of the OnePlus 7 Pro - while that makes it look perhaps less stunning, it's a more practical design from a usability point of view
  • OnePlus continues to have one of the most refined, butter-smooth, minimalistic (nearly stock), yet very useful Android skins, with some handy off-screen gestures, smart customization options, an excellent and improved 'Reading' mode, and Zen Mode to control your phone usage - the excellent software experience remains one of the primary reasons to consider a OnePlus phone
  • Breakneck speeds with the new Snapdragon 855 Plus (which is supposed to be about 15% faster than 855 with graphics), and fast UFS 3.0 storage
  • Playing graphic-intensive games is smooth, and the phone is lightning quick at launching and quitting apps, surfing the web and taking photos
  • Good, versatile, triple rear camera setup, almost identical to the OnePlus 7 Pro - the only significant difference is that the telephoto lens, while packing more pixels (12MP vs 8MP on the 7 Pro), lacks OIS, and has up only to 2x zoom (instead of 3x on the 7 Pro)
  • What that means is that picture & video quality is also very similar to the OnePlus 7 Pro - in daylight, the photos are clear, bright and vibrant with some very good HDR rendering - in low light too, the performance is more than decent, and the Night mode helps with that
  • The wide-angle camera takes bright and sharp landscape photos, and the pictures don't show much warping around the corners, as wide-angle cameras tend to do
  • The new macro mode is good too - allowing you to take pictures of objects closer and with much more in focus than before
  • Portrait shots are also great - the fallout between the foreground and background looks smooth and natural, and you can now take portrait photos with the wide-angle camera as well
  • The 16MP front camera is good too - again similar to the 16MP front camera on the OnePlus 7 Pro
  • Uses its earpiece as a speaker, which gives the OP7T an excellent stereo audio setup - it's even slightly louder than the 7 Pro - and one of the best stereo audio setups on a current smartphone
  • Good battery life with a 3800mAh battery, and a 1080p screen - you will comfortably get a day's use, even with the 90Hz display
  • Amazingly fast charging with the new Warp Charge 30T technology - it charges to 34% in 15 min, and 68% in 30 min
  • On the whole, the OnePlus 7T is an excellent, top-grade addition to OnePlus' tradition of providing top-grade flagship devices at surprisingly reasonable prices - arguably its best value device in recent times - it's again the new 'budget flagship' to beat - near perfect
  • Between this and the OnePlus 7 Pro, it will be mostly down to whether you value the curved screen and the pop-up selfie camera enough to pay the extra moolah - for most people, the OnePlus 7T will be the more sensible value choice
  • 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 camera bump at the back may be an eyesore for some (it's subjective though)
  • It's a very competent camera setup for the price, but again it's not quite up to the level of the most expensive flagships like the Galaxy S10 series, Galaxy Note 10 series, Pixel 3 series, or the iPhone 11 series
  • No included earbuds or a 3.5mm headphone adapter
  • If you want to look at even lesser expensive budget flagships though, you do have some strong options now - the two best value ones would be the Asus 6Z, and the Redmi K20 Pro - though you will be missing out on the super smooth 90Hz display and the great software experience of OxygenOS
  • 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
