2-minute Review [Positives]
  • Decent looks and build quality - very similar to the Samsung Galaxy M31, with a a unibody polycarbonate design, and glossy finish on the back panel - the only major difference is the camera module which houses a triple rear camera
  • The plastic body keeps the phone feeling relatively lightweight at 188 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 and work very well
  • 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 M21's 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
  • Decent triple rear camera setup - a 48MP primary snapper, an 8MP ultra-wide lens and a 5MP depth sensor
  • In broad daylight, you'll get consistent, crispy shots with decent dynamic range and sharpness levels are respectable with the primary lens
  • 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)
  • Live Focus shots are quite good 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 M21 does a good job of separating the subject from the background
  • The 20MP selfie camera is quite good and takes detailed selfies (though, in low light, the quality goes down a notch and results are grainy)
  • Monster 6000 mAh 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
  • If you're someone who consumes a lot of content on their phone, the Galaxy M21 is a good phone for you, it has great AMOLED display, outstanding battery backup that will last you for days
  • Gorgeous design, with some eye-catching color combinations for the (plastic) back panel
  • Very good build quality and finish
  • Fast fingerprint sensor, and face unlock
  • Good 6.3inch IPS panel, with a small dewdrop notch, and minimal bezels - it's sharp, decently bright, has high contrast, and accurate colors
  • Media playback is handled well, and videos are rendered with punchy colours
  • ColorOS 6 UI has a new, cleaner look, and is quite feature packed, including plenty of motion and screen gestures
  • Thankfully, unlike, its main competitor, the Redmi Note 7 Pro, there are no spammy ads in the UI
  • Class leading performance (especially in terms of GPU) with a Snapdragon 710 at the core - everything from daily use to complex games like PUBG is a breeze
  • The phone also doesn't heat too much even after prolonged gaming sessions
  • Excellent camera package - mostly on par with the leading camera phone of this price bracket, the Redmi Note 7 Pro
  • Packs the 16-megapixel Sony IMX519 sensor with an f/1.7 aperture - this is the same sensor used in some premium phones such as the OnePlus 6T - there's also a secondary 5-megapixel depth sensor for the phone's Portrait mode
  • In daylight, the the Realme 3 Pro captures very good details in landscape shots
  • Macros are sharp and well detailed too
  • The phone's AI scene recognition is quick to recognise most common objects such as flowers
  • Night photography is pretty decent too - and the the phone's Nightscape mode comes in handy here - it takes a second or two longer than usual to capture your shot, but the end result is a sharper image with much better detail
  • The depth sensor does a very good job with edge detection, and even in low light, you can get a very pleasing bokeh effect
  • Good 25-megapixel selfie camera too - selfies from the Realme 3 Pro pack a lot of detail and noise is kept in check - colors are excellent as well
  • Selfie portraits are quite good too, even though they don't get the benefit of a dedicated depth sensing camera - subject separation is very competent, there are no clipped ears and blur is natural-looking as well
  • Good video recording performance too - with good overall footage quality, and nice color reproduction
  • The single speaker gets loud enough for media playback
  • Excellent battery life - the combination of a large 4045mAh battery pack, an efficient processor, and Realme's optimizations means that this an easy 2-days battery life phone, even beating out (slightly) the excellent Redmi Note 7 Pro in battery life tests
  • Super fast VOOC fast charging using the bundled charger is again class-leading - it can top up the battery from zero all the way to 90 percent in about an hour
  • Overall, the Realme 3 Pro is absolutely great bang-for-the-buck, and is pretty neck-to-neck with the other top phone in this price bracket - the Redmi Note 7 Pro - while the Redmi Note 7 has a more premium glass build, and the modern USB Type-C port, the Realme 3 Pro has an edge in terms of a bundled fast charger, a slightly better processor, and cleaner (ad-free) software
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 M21'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 9 Pro and the Realme 6 are much better options that will handle gaming better than the Galaxy M21
  • Photos taken in low-light are average - focusing gets worse in low light and the extreme noise-correction makes images look like water paintings
  • Overall, the cameras on the M21 are decent, but there are better cameras available in this price bracket, including the Galaxy M31, which is just a tad bit pricier
  • Samsung Galaxy M11 falls behind in fast charging as competitors are offering close to 30W fast charging, the 15W on M21 feels low
  • Having said that, the Redmi Note 9 Pro and the Realme 6 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 Realme 6 or the Redmi Note 8 Pro that are probably the best phones for gaming in this segment
  • Realme continues to pre-install quite a few third-party apps such as a Webnovel, NewsPoint, ShareChat, etc (though most of them can be uninstalled)
  • Video stabilization at 1080p could have been better though
  • Uses the old microUSB port, instead of the modern USB Type-C port
