2-minute Review [Positives]
  • Decent looks and build quality - very similar to the Samsung Galaxy M30s, with a a unibody polycarbonate design, and glossy finish on the back panel - the only major difference is the camera module which now packs a fourth camera
  • The plastic body keeps the phone feeling relatively lightweight at 191 grams, which is mighty impressive for a phone packing a big 6000 mAh 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+ Super AMOLED 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 optimised for large displays like this
  • One UI also brings in other useful stuff, like a System-wide Dark mode (which turns the background completely black, and looks great on the M30s' AMOLED display), and Always On Display option
  • Decent performance with the Exynos 9611 at the core (similar to Snapdragon 665) - the device is fairly quick to load up apps - multitasking is a breeze
  • Good quad rear camera setup - 64MP main sensor, a 8MP wide-angle lens, a 5MP depth sensor and a 5MP macro camera
  • Shots taken with the primary camera during daylight are quite satisfactory, images are detailed, especially the 64MP shots, and they showcase good dynamic range
  • The ultra-wide sensor, like on any budget phone, is a good addition - it takes social media-worthy images in great lighting conditions (in low-light, the quality dips and pictures look grainy and noisy, wide-angle shots also have barrel distortion at the edges)
  • Photos taken in low-light looks good - switching to Night mode helps reduce grain in the output and further improves image quality
  • Live Focus shots are quite impeccable and the camera app does give you the option to set the level of blur before taking a shot - edge detection is very good and the Galaxy M31 does a good job of separating the subject from the background
  • The macro camera takes decent shots outdoors (though, the quality dips when indoors and the output is restricted to 5MP in resolution)
  • The 32MP selfie camera is quite good and takes detailed selfies (though, in low light, the quality goes down a notch and results are grainy)
  • Overall, the cameras on the M30s are good for the price bracket, even though they are not the best (that title crowned to the POCO X2)
  • 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
  • Samsung has seen success with the Galaxy M30s, so it didn't want to fix what isn't broken, they upgraded the RAM, put in a fourth rear camera, and preloaded Android 10 - if you don't care for benchmark scores and just want a device that covers the basics and has great AMOLED display, has great battery backup and has a versatile set of cameras, the Galaxy M31 will do just fine
  • Catchy, elegant 'Sunrise' rear design, similar to the Realme 5i - the back panel produces a sun-ray like pattern when light hits it which looks stunning
  • Trendy, tear-drop notch front design - the bezels on the sides are impressively thin for smartphones at this price
  • The matte finished back with lines and patterns almost completely eliminates the chances of getting fingerprints or smudges - it also adds a lot of grip and gives the phone a very solid, sturdy feel
  • The 20:9 aspect ratio makes the smartphone tall and slim, so it's relatively comfortable to hold and use
  • Face recognition is quick to unlock the smartphone in different lighting conditions
  • Large, 6.5 inch IPS display with HD+ resolution - the colors are vibrant with a decent amount of sharpness
  • Sunlight legibility is also good - the display gets bright enough for comfortable outdoor use
  • The Realme C3 comes with Realme UI based on Android 10 which is much more streamlined and clean compared to previous realme phones - it still packs a lot of useful features like Dark mode, Focus mode, Game Space and Personal Information Protection
  • Excellent performance for the price - the MediaTek Helio G70 throws the competition out of the park and scores even higher at benchmarks than the much pricier Galaxy A51 and the Oppo F15 - there's no noticeable lag in regular use and PUBG Mobile on the Realme C3 defaulted to High presets and ran fairly smooth
  • Decent dual camera setup for the price - a 12MP primary shooter + a 2MP depth sensor
  • In daylight, the Realme C3 is quick to lock focus and does a fair job of metering light, photos look good and the quality is better than what some of the other smartphones at this price point can produce
  • There's also a decent Macro mode which lets you get very close to the subject (focusing at close distance could be an issue though)
  • Decent portrait mode, with good edge detection (though, the quality could have been better)
  • Decent video recording quality, with a option to shoot slow motion videos
  • Impressive battery life with a big 5000 mAh battery - it lasts for two full days on a single charge with moderate usage
  • The Realme C3 is an easy smartphone to recommend and a solid update to the Realme C2 - it packs a powerful SoC, battery life is excellent, offers a large screen for media consumption and camera performance is acceptable for the price
2-minute Review [Negatives]
  • The power button and volumes are quite flush with the frame which means they lack that tactile, clicky feel
  • Design feels a bit dated and underwhelming, there is no spark in Galaxy M31's design as we see in other brand's phones like Xiaomi and Realme
  • However, this is an old chipset and heavy gaming isn't best on this phone - the Redmi Note 8 Pro, the POCO X2 and the Realme XT are much better options that will handle gaming better than the Galaxy M31
  • Samsung Galaxy M31 falls behind in fast charging as competitors are offering close to 30W fast charging, the 15W on M31 feels low
  • Having said that, the Redmi Note 8 Pro and the Realme X2 will still offer you more bang for your buck overall and when it comes to intensive tasks like gaming, you’ll be better off choosing the POCO X2 or the Redmi Note 8 Pro that are probably the best phones for gaming in this segment
  • A bit heavy, at 195g
  • There is no Widevine L1 certification which means that you cannot enjoy HD content on Netflix and Amazon Prime
  • There's still some bloatware that comes pre-installed
  • Low light photos are average, as expected, they lack detail and aren't very sharp
  • Selfies are average too with inaccurate colour tone and low sharpness and details
  • Still offers the old MicroUSB, while the competition has started offering USB Type-C in the budget segment
  • Charging is on the slower side with the 10W charger - it takes over 3 hours to charge the smartphone completely
