2-minute Review [Positives]
  • Sleek, classy design - the Galaxy M51 seems identical to the Galaxy A51, with a glossy polycarbonate back design - giving it a premium look
  • The front gets a new trendy look with a hole-punch display, similar to the Galaxy M31s
  • The phone feels solid in the hand - the 'glasstic back' offers better grip, and it is not as slippery as other phones with a glass back
  • The side-mounted fingerprint scanner is quick to unlock the device
  • Punchy, vivid and massive 6.7-inch FHD+ Super AMOLED display - the display is one of the best in class panels with great colour reproduction and viewing angles
  • 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 Dark 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
  • 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 M51's AMOLED display), and Always On Display option
  • Very good performance from the Snapdragon 730G - the chipset and Samsung’s OneUI optimization could take anything that you throw at it, switching across apps, moving across the UI, multitasking, and opening multiple Chrome tabs, social media is a breeze - heavy games like Call of Duty run smoothly without any lag
  • Samsung has fixed the only major drawback it had in other M-series phones with average performance, and this time the Galaxy M51 has no issue taking on the competition in performance
  • Good quad rear camera setup - 64MP main sensor + 12MP wide-angle lens + 5MP depth sensor + a 5MP macro camera - the Galaxy M51 carries the same camera setup as seen on the Galaxy M31s
  • Shots taken with the primary camera during daylight are quite satisfactory, images are detailed, especially the 64MP shots, and they showcase the good dynamic range
  • The ultra-wide sensor, like on any mid-range 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 single take is a nice addition from the more expensive S20 series, it lets you capture multiple formats at once
  • 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 M51s are good for the price bracket, even though they are not the best
  • Mammoth, out of this world 7000mAh battery delivers an incredible 2-3 days of heavy usage easily, making the Galaxy M51 the largest battery life smartphones currently available
  • Supports 25W fast charging - the phone takes around 2 hours to charge the battery completely, which is decent
  • The Galaxy M51 brings very good value as its big battery, powerful cameras, and expansive display all help make a solid argument in the device's favour - the phone's Snapdragon 730G SoC also ensures that M51 offers enough in terms of raw power to help it tackle most things you throw at it
  • Charming, fresh rear design - the Realme 7 Pro features a mirror-split design, which creates some interesting patterns when light hits it
  • The front now has a single camera which sits to the top-left of the phone and looks sleek
  • Even though it uses plastic for the frame, the Realme 7 Pro feels well-built and sturdy
  • The in-display fingerprint sensor works well, and face recognition is equally quick
  • The Realme 7 Pro is slimmer (8.7mm) and lighter (182g), compared to the Realme 6 Pro - makes it a lot more comfortable to hold and use
  • Punchy, vivid AMOLED 6.4 inches panel - it is bright, colours are rich, and thanks to this type of panel, the 7 Pro has an always-on display mode
  • Software on the Realme phones is much improved since the company switched to Realme UI, it is easy to use - it is also packed with features such as Digital Wellbeing, Focus Mode, Dark Mode, and Riding Mode among others - there are some exciting and useful features like Realme Dual-Mode Audio, which allows you to connect a Bluetooth and a wired headset at the same time to listen to music on the smartphone
  • There are still several pre-loaded apps however (though most of these can thankfully be uninstalled)
  • Excellent performance for the price - the Realme 7 Pro gets to keep the same SOC as the 6 Pro, the Snapdragon 720G is a powerful chip, so as expected, general usage and multitasking is handled superbly - gaming performance is nothing to scoff at, the phone handles heavy games like PUBG mobile with ease
  • Good quad cameras at the back - the main unit boasts a 64MP sensor, with an 8MP ultra-wide lens, a 2MP micro and a 2MP depth sensor - Realme has upgraded the main sensor with a Sony sensor instead of a Samsung sensor on the Realme 6, everything else remains the same
  • The daylight photos from the main sensor preserve the natural colour and have good exposure - it exhibits improved dynamic range, with better details compared to the Realme 6 - the new sensor is slightly better than the old one in the Realme 6
  • The ultra-wide camera captures a wider perspective but details and colours are weaker compared to the main sensor as expected
  • Portrait shots generally look good, and you get the option to adjust the background blur before shooting
  • Low light photos look cleaner too, with less grain - shots captured using Night mode look more pleasing, compared to what the Realme 6 can produce
  • The 16MP camera can take decent selfies - The selfie portrait mode is useful as it manages to correctly crop out the background, and there's also Night mode for bright selfies even in the dark
  • Video rec. is decent, you have the option to rec. up to 4K without stabilisation - there's also Ultra Steady mode which offers great stabilisation but videos look a bit soft - ultra-wide camera videos are stabilised but less detailed, the resolution is limited to 1080p
  • Overall, the cameras on the Realme 7 are a bit improved than the previous gen, which always a good thing
  • The Realme 7 Pro boasts a stereo speaker setup - the stereo effect is good, as the earpiece gets almost as loud as the bottom-firing speaker, and Dolby Atmos helps boost the volume and audio fidelity
  • Very good battery life from the 4500 mAh battery - even with medium to heavy usage, it will get you a day and half of runtime on one charge
  • 65W SuperDart Charge fast charging is best in class and takes just about 40 mins to fill up the phone
  • Realme has done a fairly good job in crafting the 7 Pro - it brings some meaningful upgrades to the Realme 6 Pro in the form of an AMOLED screen, stereo speakers, and much faster charging
2-minute Review [Negatives]
  • The Galaxy M51 feels hefty at 9.5mm thickness and 213g weight - it is difficult to use for a longer duration for calls, streaming, or even gaming
  • The back of the Galaxy M51 is a fingerprint magnet - it can also get scratched easily since it is plastic
  • The display lags with a 60 Hz display, where competing phones like OnePlus Nord offer higher 90 Hz refresh rate
  • There's still great competition at this price and the OnePlus Nord has a lot up its sleeve with a newer processor, higher refresh rate display, and a best in class software
  • Realme downgraded the display in terms of refresh rate and it's a 60 Hz display
  • The 2MP macro camera is not great, and even photos taken in broad daylight look quite poor
