Oppo is a major global smartphone manufacturer based in China known for its flagship as well as affordable Android smartphone lineup.

The F19 Pro from Oppo is one of the latest mid-range Android smartphones launched as a successor to the popular F17 Pro smartphone and retails in the Indian market for just Rs.21,490.

Design and Build Quality

Design is one of the strong fortes for Oppo smartphones from day one. The premium look and feel of Oppo smartphones made them stand out from the rest of the competitors.

The same is the case with the Oppo F19 Pro. The high-quality polycarbonate back with glossy back reminds us of glass-backed smartphones but with the advantage of reduced weight.

However, the glossy back is a fingerprint magnet and you might want to use this smartphone with a cover to avoid fingerprint smudges.

The fit and finish of this smartphone is well worth the asking price. Weighing at just 172g, this device is easy to carry around and use with a single hand.

At the bottom section of the frame, we have the 3.5mm audio jack. Type-C charging/data syncing port and the single speaker.

The power button and the volume rockers are on the right side of the frame, easily accessible to the fingers.

This mid-range Android device from Oppo features an in-display fingerprint scanner that is quite fast and accurate in unlocking the device.


The Oppo F19 Pro features a 6.43-inch Full HD+ Super AMOLED display with a resolution of 2400 x 1080 pixels.

Being an OLED panel, the colours are rich and vibrant with inky deep blacks and an impressive contrast ratio.

Thanks to the 409ppi pixel density, the visuals and text appear sharp and clean without any sort of pixelations whatsoever.

This is a standard 60Hz refresh rate panel but with an enhanced touch response sampling rate of 180Hz.

This OLED panel comes with a peak brightness of 800nits, ideal for effortless indoors as well as outdoor usage.

Processor and Performance

The processor inside the Oppo F19 Pro is the MediaTek Helio P95 which is an octa-core CPU that offers smooth performance with decent power consumption.

The 8GB LPDDR4X RAM onboard makes sure the apps and games run just fine without any sort of lags or stutters, even while multitasking.

Most of the modern gaming titles such as COD: Mobile and PUBG can be played at high graphics settings without any frame drops.

The 128GB UFS2.1 storage is fast enough to deliver stutter free everyday usage and you can further increase the storage capacity with the help of an SD card slot.

Oppo F19 Pro comes loaded with the ColorOS 11.1 skin running on top of the latest Android 11 OS. The new generation of ColorOS has been greatly redefined to embrace minimalism and it runs butter smooth as advertised.


The Oppo F19 Pro sports a quad-camera setup in the rear consisting of a 48MP primary shooter followed by an 8MP ultrawide, 2MP macro and a 2MP B&W lens.

The primary shooter has an aperture size of f/1.7 and supports phase detection autofocus. The pictures and videos from this camera come out clean and rich in details with close to natural colour tones.

There is a slight change in the colour tone when switched to the wide-angle shooter, but that has to be expected with budget smartphones.

The rear cameras can record 4K videos at 30fps while the front camera caps the video at 1080p/30fps.

The 16MP selfie camera works just fine, but the skin tone appears to be a little soft but nothing major that can’t be fixed with a software update in the future.

Battery Life

The Oppo F19 Pro is powered by a 4310mAh that easily lasts for a day on normal to heavy use.

Oppo has included a 30W charger inside the box that juices up the battery from 0-100% in just 1 hour 15 minutes.


If you’re after a lightweight device that has an awesome display and decent performance, then Oppo F19 Pro is the best choice for you.

Redmi Note 10 Pro Max is the latest offering from the Redmi Note series lineup succeeding the Note 9 Pro Max released last year.

Redmi Note 10 Pro Max is the first-ever Note series smartphone from Redmi to feature an AMOLED display instead of the LCD.

Design and Build Quality

The Redmi Note 10 Pro Max has a glass sandwich design similar to that of its predecessor, the Note 9 Pro Max.

The front glass is protected by Corning’s Gorilla Glass 5 but Xiaomi hasn’t mentioned any such protection to the rear glass.

The main difference in terms of design between the Note 9 Pro Max and the Note 10 Pro Max is the camera bump design. The rear quad camera setup now rests towards the left side.

The volume rockerz and the power button that doubles up as a fingerprint scanner is positioned at the right side of the frame. While the Type-C charging port is situated at the bottom, the IR blaster and the 3.5mm headphone jack flanks to the top section.

The Redmi Note 10 Pro Max features dual stereo speakers for loud and clear sound output.

By no means is the Redmi Note 10 Pro max a phone for single-handed usage. You should be careful about the phone tipping from your hands if used with a single hand.


The Redmi Note 10 Pro Max features a 6.67-inch 120Hz Full HD+ Super AMOLED display with a resolution of 2400 x 1080 pixels.

This gorgeous OLED display has a 395ppi pixel density that results in sharp and clean visuals as well as text without any pixelations whatsoever.

The front screen is protected by Corning’s Gorilla Glass 5 to minimize the chance of accidental scratches.

The colours on this panel look gorgeous. This is an HDR10 certified panel with excellent contrast ratio and brightness levels. If you are a media consumption enthusiast, you’ll love this display for sure.

The enhanced 120Hz refresh makes everything feel buttery smooth. The scrolling animations to the gaming visuals – it is a league apart when compared with the standard 60Hz displays out there.

Last but not the least, this OLED panel has a peak brightness of 1200nits, making it one of the brightest panels in this price segment.

Processor and Performance

The Redmi Note 10 Pro Max is powered by a Qualcomm Snapdragon 732G octa-core SoC clocked at 2.3GHz.

This processor coupled with the Adreno 618 GPU runs the show pretty effortlessly – be it casual usage or heavy gaming.

The 6GB RAM does a good job in keeping the apps in memory most of the time, even during multitasking.

The 128GB UFS2.2 storage offers faster data transfers and superior day to day performance. You have the provision to increase the storage further with the help of a micro SD card.

This smartphone comes with the MIUI 12 skin on top of the latest Android 11 OS.


The Redmi Note 10 Pro Max for the first time in the budget smartphone segment has brought the 108MP Samsung HM2 sensor to the market with this smartphone.

This is an f/1.9 dual pixel PDAF supported sensor that captures the photos and videos with a lot of details without compromising on the colour profile at all.

The feature-rich camera app has a host of nifty tricks that will help you fine-tune the photos and videos to match your expectations.

The rest of the cameras include the 8MP ultrawide sensor, 5MP macro and the 2MP depth sensor for bokeh mode photos.

The rear camera is capable of 4K video recording up to 30fps. Even the macro mode camera can record close up videos at 1080p resolution.

In the front, the 16MP sensor does a decent enough job to capture good looking selfies, but at times the quality is questionable mainly due to the software oversharpening.

Battery Life

The Redmi Note 10 Pro Max is powered by a 5020mAh battery and with moderate to normal use this phone will last you a day of usage.

Do note that a higher refresh rate might accelerate the battery drain but it is not drastic as we expected.

Xiaomi has bundled the 33W fast charger inside the box that will charge up the battery from 0-60% in just 30 minutes.


The Redmi Note 10 Pro Max is a feature-packed Android smartphone that checks most of the right boxes for a budget of Rs.20,000.

Average selfie camera

Realme is a Chinese smartphone manufacturer that gives a tough competition to Xiaomi in terms of providing customers with affordable feature-rich Android smartphones.

The all-new Realme X7 is a mid-range smartphone packed with a lot of useful features retailing in the Indian market for just Rs.19,999.

Design and Build Quality

Realme is no stranger to using flashy colours and accents on their budget smartphones.
The Realme X7 is one of the most flashy Android smartphones available in the Indian market as of now.

Weighing at just 176g, this smartphone is 8.1m thick and feels comfortable in the hand. You can carry this device in your pocket without even noticing it is there.

Unlike most other smartphones in the market, the Realme 7 flaunts the volume rockers on the left side of the frame and the power button on the right. The fingerprint scanner is tucked underneath the display.

Unfortunately, there is no audio jack on this smartphone but a single USB Type-C port for charging and data syncing. Realme has provided a Type-C to 3.5mm converter in the box if that’s of any use.


The Realme X7 features a 6.4-inch Full HD+ Super AMOLED display with a resolution of 1080 x 2400 pixels.

Surprisingly, this smartphone has a standard 60Hz refresh rate but comes with an enhanced 180Hz touch sampling rate for precise touch input response.

Being an AMOLED panel, the blacks appear dark and the colours seem to pop out bright and vivid. Thanks to the higher pixel density count, the visuals appear sharp and detailed without any kind of pixelation.

With a peak brightness of 600nits, this display fares excellently indoors and fairly decent under direct sunlight as well.

Processor and Performance

The Realme X7 has the brand new MediaTek Dimensity 800U SoC with 5G radio support on board.

The new Dimensity series processors from MediaTek has significantly reduced the gap between competing Snapdragon processors in terms of performance.

The 6GB LPDDR4X RAM onboard assists the processor to handle daily chores and resource-intensive tasks like a champ, without breaking any sweat.

Thanks to the 128 UFS2.1 storage, the apps load pretty snappily and the data transfer speeds are commendable as well.

You will be able to run almost all of the modern gaming titles on this smartphone without a hitch.


The Realme X7 houses a triple rear camera setup consisting of a 64MP primary camera, an 8MP ultrawide and a 2MP macro lens.

Photos clicked in daylight turn out pretty good with a good amount of details and colour accuracy. The green seems to be a bit oversaturated but it is a software issue and can be fixed with an OTA update nevertheless.

The ultrawide sensor captures a lot of subjects when compared to the primary shooter. The colours and details from this sensor are better than what we had expected.

The 16MP front shooter delivers average quality selfies with a softer skin tone.

Battery Life

Realme X7 is powered by a 4310mAh battery that will easily last for a day and a half with moderate usage.

The bundled 50W super dart charger juices up the battery from 0-50% in just 18 minutes, which is mindblowing, to be honest.


The Realme X7 is one of the best budget smartphones offering a mix of great performance and feature completeness for a budget under Rs.20,000.

  • Decent casual performance

Average processor

Vivo is a prominent Chinese smartphone manufacturer popular for its affordable lineup of Android smartphones in the Indian market.

The Vivo V20 SE is a camera-centric smartphone packed with a decently powerful chipset priced under Rs.20,000.

Design and Build Quality

Vivo has done an incredible job in terms of the design of the Vivo V20 SE. This smartphone looks premium with the glossy finish back and gradient colours.

This is a lightweight device and easy to operate with one hand. Weighing at just 171g, this device is lightweight and the slim form factor makes it easy to be carried around in the pant pockets.

The Vivo V20 SE features a 3.5mm audio jack, USB Type-C port, speaker grill and primary mic for calling at the bottom section of the middle frame.

The top section houses the secondary noise cancellation microphone along with the SIM tray with dual SIM slots and a dedicated microSD slot for memory expansion.

The power button and the volume rocker is positioned towards the right side of the middle frame.


The Vivo V20 SE features a 6.44-inch Full HD+ AMOLED U-notch display with a resolution of 1080 x 2400 pixels.

With a pixel density of 409ppi, this OLED display looks stunningly vivid and detailed. The colours pop out of the screen, thanks to the near-infinite contrast ratio offered by the OLED technology.

The display gets very bright indoors and when used outdoors, the screen is legible enough for the most part.

Except for the slightly thick bottom chin, the bezels on the top and sides are narrow, facilitating an immersive media consumption experience.

Processor and Performance

This is where the Vivo V20 SE is a huge disappointment. This device packs the yesteryear midrange Snapdragon 665 octa-core processor onboard.

While this is a perfectly capable everyday processor that can handle casual tasks such as web browsing and social networking, it isn’t that powerful enough for gaming and intense multitasking.

The 8GB RAM onboard makes sure the apps never run out of memory even when used side by side.

Regarding storage, the Vivo V20SE comes with an ample 128GB capacity with the option to further expand via the dedicated SD card slot.

Surprisingly, the Vivo V20 SE is one of the first smartphones in India to launch with the latest Android 11 out of the box.


The Vivo S20 SE has a triple rear camera setup with the primary shooter being a 48MP camera followed by the 8MP ultrawide and 2MP depth-sensing unit.

The photos captured with the 48MP sensor have a good amount of details and the colours look close to natural when compared with some other Vivo smartphones.

The 8MP ultrawide lens is perfectly usable under good lighting conditions but once the light fades, a significant amount of noise creeps into the clicks.

The camera app is fully loaded with features such as AI filters and stickers that can be used to enhance the fun element in amateur photography.

The Selfie camera was and is one of the main selling points of Vivo smartphones. The 32MP shooter on this one doesn’t let us down in terms of the quality.

Battery Life

The Vivo V20 SE is powered by a 4100mAh battery that will easily last you for a day of heavy usage without much trouble.

The bundled 33W adapter supports fast charging and juices up the battery completely from zero to a hundred per cent within an hour.


The Vivo V20 SE is a thin and lightweight Android smartphone with the latest Android 11 OS on board and decent everyday performance.

If you don’t use the phone much for gaming, the Vivo V20 SE is perfectly fine for your casual smartphone usage.

Best Budget Smartphone

  • Capable 64MP rear camera module
  • Long-lasting battery life


Intuitive OneUI 2.0


Non-Chinese smartphone


15W fast charging


Not for gaming

Samsung Galaxy F41 is the newest smartphone offering from the South Korean multinational conglomerate in the budget price segment in India.

Samsung markets this sub. Rs.15,000 smartphone as a camera-centric device targeting photography enthusiasts on a shoestring budget.

Design and Build Quality

The Samsung Galaxy F41 looks and feels almost similar to many other M series models that we had reviewed on our site in the past.

The plastic back with a glossy finish has been retained here as well to cut the cost as well as reduce the overall weight of the device.

The power button and volume rockers are located on the right side of the plastic frame. These buttons are very tactile and offer responsive feedback.

The physical fingerprint scanner is located on the rear section beside the rectangular-shaped camera module.

This scanner is very accurate and feels much faster to lock and unlock the device.

As with any other modern device, the Galaxy F41 features a USB Type C port for charging and data transfer as well as a 3.5mm headphone jack for wired audio connectivity.


Samsung is known for its quality OLED panels in the budget smartphone segment which very few other smartphone OEM dare to offer.

The Galaxy F41 features a 6.41-inch FHD+ sAMOLED display with a native resolution of 1080 x 2340 pixels.

This is a 19.5:9 aspect ratio panel with an infinity U shaped notch up top.

With an impressive pixel density of 403ppi, this OLED panel has inky deep blacks, vivid and bright colours and an excellent overall dynamic range.

This display gets quite bright at 420nits which makes it quite easier to use even outdoors under direct sunlight.

Processor and Performance

This is one area where the Galaxy F41 disappointed us.

This smartphone from Samsung still packs the older Exynos 9611 processor that we have seen in the likes of M21 and M31.

This octa-core processor works just fine for everyday usage but lags a bit when it comes to intense gaming.

We wish Samsung had gone with a newer version of an Exynos chip or even a comparable Qualcomm equivalent.

The base variant of this device comes with 6GB of RAM and 64GB of UFS 2.1 storage. This is very much enough for the lag-free experience even with multitasking. There is a dedicated SD card slot for increasing the storage further.


As we mentioned above, the Samsung Galaxy F41 features a triple rear camera setup.

The primary camera is a 64MP sensor with an aperture size of f/1.8 with PDAF support.

Assisting this sensor is the 8MP ultrawide sensor and 5MP depth sensor for wide-angle shots and portrait mode bokeh clicks.

The quality of pictures comes out detailed and sharp in favourable lighting conditions.

The colours look natural and vivid. Speaking of video, the F41 supports 4K and FHD video recording with decent frame rates.

The front camera is a 32MP shooter with HDR support for excellent quality selfie shots. Nighttime photos are a hit and miss depending upon the lighting and the choice of the lens.

Battery Life

The Samsung Galaxy F41 is powered by a 6000mAh Li-Po battery that is rated to last for a day and a half with heavy usage.

You can expect a screen on time of anywhere from 8-10 hours with this device.

Samsung has included a 15W fast charger in the box that juices up this device within 2.30 hours from zero to a hundred per cent.


If you want a capable non-Chinese smartphone with capable hardware, a gorgeous OLED display and long-lasting battery life, the F41 is worth checking out.

The camera module in the rear can take excellent quality day time photos and videos which make this smartphone further appealing to budget-conscious customers.

Realme has been closely trailing behind Redmi for a while in the smartphone market.

With the all-new Realme 7 Pro, the company has upped the ante in the budget smartphone segment with cutting edge features that were once reserved for higher-end flagship devices.

Design and Build Quality

The Realme 7 pro is characterized by a single punch-hole display and a gradient coloured polycarbonate back body with a matte finish glass design.

The phone weighs just 182 grams and feels light and durable in hand. This phone is relatively light when compared to the Redmi Note 9 pro max and the Poco X2 and has a more one-hand usage friendly design.

The fingerprint sensor this time is located on the side and doubles up as a power button.

The front display is protected with Corning Gorilla Glass 3+ for advanced scratch protection.

Realme has also given a splash-resistant coating on top of the glass to repel light water drops from sticking on the surface.

The standard set of features such as the USB type C port and the 3.5mm headphone jack is present and accounted for as well.


The display is one of the unique features of this smartphone priced under Rs.20,000.

The dual single punch-hole display looks similar to that of certain premium Samsung smartphones.

The Realme 7 Pro features a 6.4-inch full HD+ AMOLED panel with a resolution of 2400 x 1080 pixels with a pixel density of 411ppi.

The display looks very sharp and the colours turn out to be natural and vivid.

Thanks to the excellent contrast levels, you’ll get to see inky deep blacks and popping colours that will deliver you a delightful media consumption experience.

Unlike the predecessor, the Pro version has to suffice with the standard 60Hz refresh rate which is a bit of a disappointment, to be honest, but not at all a deal-breaker of any sorts.

Processor and Performance

The Realme 7 Pro is powered by a Qualcomm Snapdragon 730G chipset, which is custom-tuned for enhanced gaming performance.

The 6GB RAM and the super-fast 128GB UFS2.1 storage will help you experience the best mobile computing performance in the sub. Rs.20,000 price segment.

Speaking of the thermals, the phone gets slightly warm with extended hours of gaming, but nothing serious enough to throttle the performance.


The Realme 7 Pro comes with a quad-camera setup in the rear and dual cameras in the front.

The main 64MP camera comes with a 1/1.8 aperture sensor for better low light photography.

There is also an 8MP ultra-wide sensor followed by the 2MP macro camera and 2MP depth sensor.

The images come out clean and detailed in daylight and with respectable performance in the dark.

Talking about the video, there is electronic image stabilization to keep your footage steady and smooth.

The front 32MP camera offers excellent selfies with realistic bokeh effects. Additionally, this camera also supports EIS for videos.


The Realme 7 Pro runs on the all-new Realme UI 1.0 based on Android 10. This custom skin is much more refined than the previous Color OS which realme phones shipped with in the past.

This budget Android smartphone comes with an in-display fingerprint scanner – thanks to the AMOLED display.

This newer generation scanner is fast and accurate to unlock your device just as quick as a physical scanner would do.

Battery Life

The Realme 7 Pro is powered by a 4500mAh battery that will easily last over a day with heavy usage.

To make things better, there is the 65W super dart fast charging support with the charger available in the box.

This charger will completely juice up the battery from zero to a hundred per cent within 40 minutes flat.


The Realme 7 Pro is a fantastic value for money smartphone perfect for resource-intensive tasks such as gaming.

The gorgeous AMOLED along with the powerful processor and long-lasting battery makes it a champ in its price segment.

Design and Build Quality

With 8GB of RAM, multitasking is great and the device breaks no sweat processing two resource-intensive apps side by side.

The device comes with 128GB of inbuilt UFS 2.1 storage and comes with a dedicated slot for memory cards.

In-display Fingerprint Scanner

The Oppo F17 is perhaps one of the cheapest smartphones which come with an in-display fingerprint sensor.

Even though this technology is in the nascent stage, it works relatively well and is almost as fast as conventional fingerprint sensors.


In the rear, the Oppo F17 features a quad-camera setup consisting of a 16MP main sensor, an 8MP ultra-wide sensor, and two 2MP mono lenses for AI filters.

Numbers-wise, the 16MP sensor might sound pretty low for this price, but performance-wise the quality of pictures turned out to pleasantly good with ample details and colour accuracy.

The low light photo/video performance from this sensor can be said to be decent at best.

The front camera on this device is a 16MP sensor with an aperture size of f/2.0 and has HDR support for selfies with good dynamic range.

Both the front and the rear camera supports Full HD video recording up to 30fps.

Battery life

What makes this device stand out from the rest is the design. The phone is a stunner when it comes to looks and is sure to turn some heads in the crowd.
