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
  • Decent looks and build quality - with a a unibody polycarbonate design, and glossy finish on the back panel - quite similar to the M30 - the only major visual difference is that the triple camera setup gets a wider, rectangular module to house the LED flash and "48 megapixel" branding
  • The plastic body keeps the phone feeling relatively lightweight at 188 grams, which is mighty impressive for a phone packing a big 6000mAh battery
  • It also feels great to hold with a seamless curved panel that meets the display up front
  • Modern, Infinity-U front - bezels around the screen are slim, except for a slightly thick chin - you still get around 90 per cent screen-to-body ratio, which is great
  • Fingerprint sensor at the back is easy to reach
  • Gorgeous, 6.4-inch FHD+ (2340x1080) Super AMOLED Infinity-U display with excellent viewing angles, and brightness levels - easily one of the best displays in the price bracket
  • It also comes with "Widevine L1" certification, which helps stream content in crisp HD resolution
  • Blacks are deep on the AMOLED display, which looks good with Night mode enabled
  • Samsung's OneUI is today one of the more clean, refined Android UIs that's especially well optimized for large displays like this
  • One UI also brings in other useful stuff, like a System-wide Night mode (which turns the background completely black, and looks great on the M30s' AMOLED display), and Always On Display option
  • Good, strong performance with the Exynos 9611 at the core (similar to Snapdragon 665) - everyday performance to high-end gaming - everything is handled smoothly
  • Decent rear camera setup - 48MP main sensor + 8MP wide-angle lens + 5MP depth sensor
  • With the primary lens, you get bright and attractive photos in daylight conditions with vibrant colours and good contrast - dynamic range is also wide and noise is controlled
  • Switching to the wide-angle lens will offer a new perspective, letting you click a wider area at close range to the subject (it is best used in daylight, however, as wide-angle captures look grainy and noise indoors or in low light)
  • The dedicated Night mode can be used with the main camera - it comes in handy in low-light conditions, extending the shutter time to allow more light into the frame - making for some decent low-light photos
  • Live Focus does a decent job at separating the subject from the background, and giving good bokeh shots
  • The 16MP selfie camera too does a decent job when it comes to capturing selfies outdoors under bright light (though it starts to struggle indoors and in low light, offering softer selfies with a lot of grain)
  • Overall, the cameras on the M30s are decent for the price bracket, even though they are not the best (that title is shared by Xiaomi and Realme phones)
  • Monster 6000mAh battery delivers an incredible 2-3 days of usage easily, making for one of the largest battery life smartphones currently available
  • Supports 15W fast charging
  • With the M-series performing well for Samsung, M30s is well-set to add to that success, delivering a good all-round package with one key differentiator - an incredible battery life - if that is one of your primary concerns in a phone, then the M30s is a no-brainer (if on the other hand you want the best camera or best performance for your buck, you can look at Xiaomi or Realme phones in this price bracket)
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
  • The power button and volumes are quite flush with the frame which means they lack that tactile, clicky feel
  • Lacks the premium finish of some of its competitors
  • Focusing is slow at times
  • Overall low light camera performance still feels lacking
