2-minute Review [Positives]
  • Stylish, impressive dual-color 3D gradient design, and good built quality
  • The curved back panel gradually meets the side to provide an easy-to-hold experience
  • Decent, large 6.5-inch IPS LCD screen with HD+ (720×1600 pixels) resolution, an 82.5 percent screen-to-body ratio, and a water-drop notch
  • Decent color reproduction and brightness
  • Widevine L1 certification for HD video playback on Netflix and Amazon Prime Video
  • ColorOS is a fairly refined, sophisticated custom Android skin, with a number of useful add-on features
  • Solid performance with a Snapdragon 665 powering the internals - both day-to-day stuff, and gaming is smooth
  • Decent overall camera performance for the price bracket
  • The device comes with a quad-camera setup - a 48-megapixel primary sensor + 8-megapixel ultra-wide lens + two 2MP cameras for "artistic portrait effects"
  • You get good results in ideal lighting conditions across the board - the 48-megapixel primary sensor captures good images with decent texture, colors, and detail - the camera can capture impressive images in an ideal or sometimes challenging situation with good amount of dynamic range
  • The camera manages to take okay images in low light, but things improve dramatically with the dedicated “Night” mode
  • With the portrait mode, the A9 2020 does a decent job in background separation (though the 2 additional cameras for "artistic portrait effects" don't seem to add much value)
  • Decent 16-megapixel front camera sensor for selfies
  • Offers a good stereo audio effect with its bottom and top firing speakers
  • Very good battery life with a large 5000mAh battery - you will comfortably get 2 days of use
  • Support for reverse charging - you can use the device as a power bank to charge another smartphone
  • 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
  • Good 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 good 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]
  • A bit bulky
  • Like all glossy rear panels, the rear does easily attract fingerprints and smudges
  • The panel is quite glossy so you may find it difficult to read content under direct sunlight
  • Like most custom Android skins, it's not quite as simple, and clutter-free as stock Android
  • It's definitely not category-leading performance though, many competitors provide faster processors
  • Overall, while the camera setup is good for the price bracket, again it's not category leading
  • No fast charging support (the included 10W charger inside the box with charges the device from 0 to 100 percent in about 2 hours and 25 minutes)
  • On it's own the Oppo A9 2020 is a pretty decent mid-range phone with 2 key highlights - a stylish design and a very good battery life - but its cameras and performance are nothing special, which puts it behind a lot of the competition in this hotly contested price category
  • 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
