2-minute Review [Positives]
  • Slick, beautiful, eye-catching gradient finish on the back (though the back is laminated plastic and not glass)
  • Fairly slim and light for a phone with such a large display
  • Oppo F15's in-display fingerprint sensor and face unlock work very well - face unlock even works well in dimly lit places
  • Very good 6.4-inch full-HD+ AMOLED display with a dewdrop notch and Gorilla Glass 5 protection - the colours are good, so is the sharpness - videos look sharp, with punchy colours, and the viewing angles are quite wide
  • Display gets adequately bright and is legible even under sunlight
  • You can watch Netflix and Prime in crisp HD resolution as Oppo F15 comes with Widevine L1 support
  • ColorOS is fairly streamlined, and packs fast animations that help the phone feel snappy - there are of course several add-on features too, compared to what you would get in stock Android
  • Decent performance with the MediaTek Helio P70 SoC (similar to Snapdragon 660) - day-to-day operations are smooth and you can even play games like PUBG Mobile on 'Medium' graphics setting
  • Thermal performance is good too - the phone doesn't overheat when using the cameras extensively or even playing games
  • Good quad-camera setup at the rear - 48MP primary + 8MP wide-angle + 2MP depth sensor + 2MP monochrome sensor
  • The primary camera shoots oversampled 12-megapixel stills - in daylight, it captures fairly detailed landscape shots, colours are vivid, detail is good, and there's little to no noise in darker areas
  • The wide-angle camera has autofocus, so stills taken have good detail, close-ups are sharp and detailed too - and if you get really close to your subject with the wide-angle camera, you'll be able to get good macro shots
  • Portrait mode works decently well with human subjects and you can adjust the level of blur before taking the shot - edge detection is decent and image quality is good, when shooting under good light
  • 16-megapixel selfie camera manages some pretty good-looking stills in daylight - skin textures are smoothen a bit but HDR works well and colours are well represented - with good amounts of artificial light around, it manages to get pleasing enough selfies even at night
  • Video quality is decent and there is stabilisation when shooting using the primary camera
  • The mono speaker gets fairly loud
  • Battery life is pretty solid, backed by the 4000 mAh cell - will easily last a day and half with moderate use
  • The Oppo F15 charges pretty quickly too with the supplied 20W Charger, about 88 percent in an hour
  • Overall, Oppo F15 is a decent smartphone - it looks good, and it impresses particularly with its slimness, light weight, and good display
  • 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]
  • Oppo F15 is a tall phone - it's not the easiest phone to fit into a pocket
  • There is, as usual, some bloatware that comes pre-installed (but most of it can be uninstalled)
  • While the chip offers decent performance, this chip is typically expected in phones closer to the Rs. 10, 000 mark (such as the Realme 3) - the Oppo F15 feels underpowered, considering that the Realme X2 and Redmi K20 offer Qualcomm's superior Snapdragon 730 series SoCs at the same price
  • Selfie portrait mode doesn't work too well, unfortunately, whether it's day or night
  • There are few caveats here, like there's no option to shoot at the full 48-megapixel resolution - other features such as super-steady video and the ability to use Night mode for the selfie camera are also absent
  • In low light, image quality from both primary & wide-angle camera is average, details are weaker and there is visible noise in the darker regions - the ‘Night' mode helps brighten up scenes but the details don't improve much
  • No 4K video recording, which most of its competitors support
  • In low-light, video quality is noticeably worse with poor details and a persistent shimmer in the footage even with slight movement
  • Overall, camera performance could have been better, as two of its main competitors, the Realme X2 & the Redmi K20 offer better image quality
  • However, at this price, you're better off with either the Realme X2 or the Redmi K20 - both of which offer much better performance, even more premium build quality, and even more modern designs
  • 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
