2-minute Review [Positives]
  • Well built, sleek, modern design, with a Infinity-U display
  • Eye-catching back panel with a gradient and prism-like finish
  • Large, vivid Super AMOLED, Infinity-U display with slim borders all around - everything looks colour accurate and bright
  • The Galaxy A30s runs on Samsung's new One UI, which is one of the more polished, refined takes on an Android UI, and is one of the best Android UI implementations at present, along with Oxygen OS
  • There are a number of useful features including Android Pie's Digital Wellbeing, and a whole bunch of motion gestures such as one-handed mode, Smart Stay, etc, which can be toggled on
  • Decent performance with a Exynos 7904 processor at the core (similar to Snapdragon 636) - day-to-day use is decent and complex games like PUBG are also playable at reduced graphics settings
  • Decent triple rear camera setup - primary 25MP sensor + 5MP depth sensor + 8MP ultra-wide sensor
  • The 25MP camera reproduces objects and panoramic scenes well, colours always look vivid - the edges of objects and textures lack clarity, though
  • The Primary camera can also take good macro shots - it capture more details than when in general shots, edges of objects are more distinguishable too
  • Good video quality - on par with that of other phones in this price range
  • Front camera shoots vibrant-looking portraits
  • Good Loudspeaker
  • Good call quality - it gets loud enough to make and receive calls from noisy environments
  • The 4000mAh battery is one of the Galaxy A30s's strong suits - you will easily manage to push past a full day on one charge
  • The bundled 15W fast charger is able to take the battery to about 70 percent in an hour, which is not bad at all
  • Stunning, beautiful design, that's a treat to the eyes - Vivo S1 is easily among the most well-designed smartphones to launch this year
  • There is a mesmerising dual tone finish on the metal frame, and a unique 'diamond lattice' design back, that reflects colors in the most interesting ways - this is the kind of smartphone that will definitely get you a lot of Wows from everyone around
  • It not only looks great but also feels great to hold and use thanks to the 2.5D design
  • Fast in-display fingerprint sensor
  • Dedicated Google Assistant button
  • Very good 6.38-inch AMOLED display - you will get deep blacks and punchy colors
  • Funtouch OS UI looks very similar to iOS, and is pretty feature packed, including a good gesture navigation system, and an 'Ultra Game' mode
  • Daily performance is smooth all-round with a Helio P65 processor (similar to the Helio P70, and Snapdragon 660), and most games run well too
  • Decent set of triple rear cameras - 16MP primary + 8MP ultra-wide + 2MP depth
  • The primary camera captures images with fairly good details
  • The depth camera helps with some decent portraits
  • The 32MP selfie camera is decent too, and does especially well with details (though the image softening algorithm is a bit too aggressive)
  • Outstanding battery life with a large 4500mAh battery paired with a low-power MediaTek Helio P65 SoC - you will comfortably clock 2 days of use
  • Bundled 18W fast charger
2-minute Review [Negatives]
  • The fingerprint sensor is sluggish - and cannot recognise fingerprints accurately
  • The Galaxy A30s is also a big phone to carry around, even if you have large hands
  • The resolution is only 720p which is rather low by today's standards
  • Unfortunately, there are still plenty of promotions, and ads to deal with, in the default phone setup
  • Given however, that other phones in this price range now come with much more powerful SoCs like the MediaTek Helio G90T and the Qualcomm Snapdragon 675, the A30s does lag behind the competition in terms of performance
  • The front 16-megapixel selfie camera is average - selfies are a bit soft in daylight and in low-light, selfies lack good detail, with visible grain
  • Camera struggles in low-light conditions - it captures hardly any details and underexposes the whole scene, with a lot of noise
  • Camera app does not have a slow-motion mode
  • Overall, the A30s is not quite as good as Samsung's other recent launches in the M and A series
  • It will face very stiff competition from the likes of the Redmi Note 8 Pro, which apart from being much more powerful, also takes a big lead in the camera department
  • Even if you want to stick to Samsung, the M30s will give you a slightly better camera performance, a bigger battery, and storage - so, significantly better value
  • It's on the cluttered side though, and does have some bloatware - so the experience is not as clean and simple as stock Android
  • More complex games like PUBG though are not smooth at high graphics settings - and here the phone loses out to the best performing phones of this price bracket that pack the likes of Snapdragon 675, and Snapdragon 710
  • The ultra-wide camera provides for versatility in shot framing, but the quality is average - details are low, and the overall image is muted
  • Low light performance is average too
  • Overall, the cameras are decent for the price bracket, but not really comparable to the top camera phones of this price bracket, like Redmi Note 7 Pro, Realme 3 Pro, Realme X, and even the Vivo Z1 Pro
  • Uses the old microUSB port, instead of the modern USB-C port
  • On it's own the Vivo S1 is a pretty good device, but it faces some real tough competition at the moment - the camera and the performance are not the best for the price bracket, though if your main priorities are a best-in-class design, and excellent battery life, it could still make a lot of sense
