The Samsung Galaxy M40 is the latest smartphone in Samsung’s Galaxy M lineup of smartphones that launched in India earlier this year. It’s the most powerful device in the series yet, thanks to the Snapdragon 675 under the hood, and it also comes with features like an Infinity-O display, and 32 MP triple rear camera. But it also lacks the monstrous battery from the Galaxy M20 and M30 and a traditional 3.5 mm headphone jack.

With the launch of this smartphone, Samsung completes it’s set of new phones ranging from 8k to 20k, which has always been its strategy. Samsung has introduced the Infinity O display for the first time in this price segment- an immersive 6.3″ FHD+ display that extends from edge to edge. It is powered by the Snapdragon 675 processor along with 6GB of RAM and comes with Android Pie out of the box.

Galaxy M40 brings a new triple camera, punch-hole front camera and a new way to allow audio through the display. M40 may feel like a small phone but it isn’t, it is quietly elegant, it is frighteningly slippery, though it’ll survive a drop just fine.

I got the chance to use this device for a while now and here are my first impression on Samsung Galaxy M40.

Quick Review

Samsung Galaxy M40 is a well-balanced phone. It offers respectable power, good rear cameras, and a nice display but there are certain elements that leave a big question mark on its price. Look wise and operation wise it is a smooth phone and it operates smoothly with snapdragon. The thing that bothers me the most is its sound quality, it could have been better. Apart from these few shortcomings, it is still quite a good phone at its price.

Here is a list of pros and cons which will help you better understand whether you should buy it or not:


  • Good display
  • Lightweight
  • Punchole front design is good
  • Internal memory is good
  • Infinity O display is just amazing
  • Triple camera setup with main 32 mp camera
  • Full HD+ resolution 1080×2340 ~409ppi }– Wide vine L1 certified, runs Amazon Prime videos in true HD
  • The rear camera is quite good


  • Sound quality should have been better
  • No 3.5 mm audio jack
  • Front camera not that effective

Design and Display

7.9 mm sleek body and premium dual tone finish

Samsung Galaxy M40 Design

The Samsung Galaxy M40 is the company’s first affordable smartphone to offer a punch-hole display. In my opinion, it’s the nicest looking phone I’ve come across from Samsung in a long time. The design is good and sleek and the phone feels light too but I really miss the 3.5 mm audio Jack.

The M40 comes packed in a polycarbonate body. Nevertheless, the back has a completely different gradient design where the curved sides have a slightly lighter in weight shade of blue, and the flat part is in deep blue. The handset’s Seawater Blue hue is to die for. The corners and the Samsung logo in the center has a Galaxy A50 like rainbow reflection, which looks beautiful.

The back of the phone is a fingerprint magnet, so you’ll have to wipe it down occasionally to keep it smudge free.  The fingerprint sensor positioned at the back of the phone works really well.

The rear panel is smooth to touch. The triple camera array on the back resides in a module on the top right corner with an underline silver ring over the middle sensor. Also, the punch Hole notch for me it looks better than regular notches, wallpapers are there to hide the notch.

Coming to the Display, it has 6.3” size, with 91.8% screen to body ratio, very thin bezels on top and sides. PLS LCD display is Samsung’s proprietary technology but I wish it had AMOLED, but PLS LCD offers better viewing angles and higher max brightness. Full HD+ resolution 1080×2340 ~409ppi wide vine L1 certified, it means you can run content from Netflix, Amazon Prime videos in true HD.


Triple Rear Camera – 32MP/F1.7 Primary Camera | 5MP/F2.2 Live Focus | 8MP/123 degree Ultra-Wide Lens

Samsung Galaxy M40 Camera

The Samsung Galaxy M40 features a triple-camera on the back, which looks much better compared to its early counterparts. It has a 32MP primary shooter with an f/1.7 aperture along with an 8MP ultra-wide camera with a 123-degree field-of-view and a 5MP sensor for depth mapping. For selfies, there’s a 16MP front camera drilled in the punch-hole.

As more and more manufacturers are including a 48MP sensors in affordable prices, I have to say it is kinda shocking to see Samsung opting for a 32MP sensor. But pixel count isn’t everything. Photos I took with the device during the day had ample details, great dynamic range, and fantastic colors.

With 8MP, f/2.2, 12mm Ultrawide Camera you are able to cover a wide area around 123-degree field of view. Photography enthusiasts can play with the wide-angle to get creative and capture unconventional shots. With 5MP depth sensor camera edge detection was good in portrait shots. Your control over the background blur of the image and daylight portraits look good. Selfies were very good in daylight. The beautify mode is good. But this is the same as pictures taken from A50 which has a 25MP camera.

Samsung’s scene recognition algorithm powers the camera. Which means it optimizes the pictures after judging a picture. A quite old feature, but makes photography somewhat easier for newbies.

Battery life

3500 mAh Battery with 15W Type C Fast Charger

Samsung Galaxy M40 Battery

Samsung has outfitted the Galaxy M40 with a 3500mAh battery which also supports fast charging via the 15W adapter provided in-the-box.

With 3500 mAh Li-Po battery, you will get 1 day of battery life with normal usage. Can get 5 hours of on-screen time on heavy usage with videos, gaming and mobile data with sync which is very good. Battery optimization is very good. It just took 36 minutes to charge from 0% to 50%, but 50% to 100% might take a bit longer.

The handset is competent enough to handle everyday tasks with ease and can even play the most intensive games from the Play Store at medium to high settings. For example, PUBG Mobile which defaults to high settings on the phone and plays smoothly, though you will get better frame rates if you lower the graphics preset to HD.

The M40 smoothly runs through the day, but on heavy usage like playing video games or something you might need to recharge it again before the day ends.


M40 is powered by Snapdragon 675 chipset, it has 6GB of RAM and 128GB internal storage

Samsung Galaxy M40 Performance

In the battery department, the Samsung Galaxy M40 packs a 3,500mAh battery with USB Type-C and 15W fast charging support. Battery backup is mostly good for a day if there is heavy usage involved like playing video games you might need to recharge it before going to sleep at night. Very good Battery optimization, but still can be improved. Expecting updates to further enhance.

For regular users, the M40 will not disappoint if your usage revolves around apps like Facebook, Twitter, Instagram, WhatsApp, YouTube, and a bit of gaming. But if you are a serious gamer then you should look for a better option as there are better phones available in the same price range.

The M40 comes with the Samsung Experience 9.5 UI based on Android 9, and I have liked the UI experience on the previous M-series phones as well and this phone is no different.  

For security, Samsung provides a physical fingerprint scanner and face unlock feature on the Galaxy M40. I found the fingerprint scanner to be quite snappy. The face recognition is also quite fast, but still opens with eyes-closed, which needs to be fixed for all Samsung smartphones.

My main issue with this phone is it’s sound quality. It’s not bad or anything but I expected a much better experience given the price of this phone.

Verdict: Should you buy it?

In my opinion, Samsung Galaxy M40 is one of the finest smartphones in this price range of Rs 19,990. There’s arguably nothing apart from the punch-hole design, SD675 and the 32MP primary camera that makes the M40 a ‘better’ smartphone than the M30. It brings a lot of innovative features to the affordable segment, including its Screen Sound casting technology and its punch hole display. The phone is a delight for mobile gaming users and it offers the latest software experience out-of-the-box. It has its shortcomings like there is no headphone jack which is kinda disappointing. But which phone doesn’t have its week points. However, if you’re a sucker for the Samsung brand name, then there’s no better affordable phone for you than the M40 in the market right now.
