First, The Dashain offer provided by Samsung Electronic - instant cashback offer - makes this device even more affordable to the customers. The original price tag for the 6/128 GB variant was set at Rs. 36,190/- but a recent price drop of Rs. 6200 make this device available at just Rs. 29,990/- in the market of Nepal.

 Display and Design

Galaxy M40 is the first Samsung mid-range phone to adopt Infinity O display with a cut-out selfie camera on a display. The display of the phone resembles the look of Galaxy S10. The FHD+ (2340x1080 pixels) display covers 91.8% of the front body providing a stunning look. The 6.3-inch FHD+  display has 409 PPI, which means letters and picture looks sharp and even when looked deeply on the screen no individual pixel could be visualized.

The display technology uses TFT  panel and for daily media consumption and gaming the screen provide great visual effect but the display panel is not as good as AMOLED display which is capable to provide vibrant color with deep black and bright whites. The difference can be noticed only when phones with TFT panel and AMOLED panel are placed side by side. 

The front screen is protected by Gorilla Glass 3 pannel which does prevent scratch and crack in the display but is not good as the latest Gorilla Glass 6. The back of the phone is made up of plastic but the glossy design similar to traditional Galaxy S3 back resembles a glass body which also drags lots of fingerprints.

Hardware and Performance

This is also a first mid-range M series which features Snapdragon SoC. The Qualcomm Snapdragon 675 11 nm processor. Inside there is an Octa-core processor in which Samsung Electronics had incorporated two high performing 2.0 GHz cores with six power efficient 1.7 GHz cores, which are capable enough to process normal daily media consumption activity as well as internet surfing. More to it, users can play casual and mediocre graphics-intensive games without any issues on the device. But keep in mind that playing graphics-intensive games can sometimes drop the frame rate as well as playing for longer sessions will heat the device, which is not at the uncomfortable range.

Adreno 612 graphic processing unit (GPU) is used in the device for handling graphic intensive tasks on the phone. Paired with  6 GB RAM, customers can play popular games like PUBG, Clash Royale, Asphalt 9, etc. at medium graphics quality. Moreover, if you love to put lots of files, application music, and video 128GB storage options will be adequate. But it is great that users can expand the storage option utilizing space of SIM 2 slot. The device can support a MicroSD card up to1 TB storage capacity. Compare to what we are paying, this kind of hardware choice is excellent for the price point but the mediocre performance can not compete with the performance of the high-end flagship phones.

About the other aspect of the phone, the company removed a 3.5 mm headphone jack from this phone so customers either have to use wireless Bluetooth headphones or use USB type C compactable headphones. Another major point is that there is no front-facing earpiece. While the user makes a call, the new industrial vibrating screens allow the screen to make sound using “screen sound “ technology. So, the sound or audio will be directly come out from the screen and users do not have to rely on a specific part of the device (earpiece), and can hear the sound during phone calls at every part of the screen which produces clear and decent sound. 

Camera and Photo Quality 

At the left top corner of the screen, the front-facing 16 MP selfie camera is embedded. The photo quality is good. The photo captured looks nice and natural without making any distortion or imbalance at the saturation level. Additionally, the portrait feature can capture a photo with a nice blur background but can sometimes miss the proper edge detection.

At the back of the phone, the Vertical triple-lens camera system is present with an LED flashlight right below the camera. The primary sensor of 32 MP f/1.7 sensors can produce a decent photo. The photo quality looks good, with adequate details and color saturation. We can not expect the quality to be as good as the flagship phone but among other mid-range smartphones, Galaxy M40 can produce better overall quality photos. 

Among the triple-lens setup there reside 8 MP ultrawide cameras. The main feature of this lens is that the user can incorporate a large field of view in the photo. The greater field of view provides more content even when the object is closer to the device. The photo captured using the ultra-wide-angle lens is also good But the dynamic range of the shots sometimes lacks the details of the images. The quality of the image captured with this lens is not as good as of its primary lens. Furthermore,  5 MP depth sensors embedded in camera housing can provide a decent blur effect on the shot. It seems natural and can produce a nice portrait image. The night shot even in low light condition looks nice in the photo if we capture still object. But moving objects can produce blur shots with lots of grains and noise. 

Finally, for capturing the video, the main primary camera can be used which can capture moving objects 4K video at 30 frames per second. But for better quality and stabilization I would recommend capturing shots in 1080p at 60 fps. There is no OIS or EIS technology incorporated to stabilize the shot so only software optimization is done to prevent shake while capturing video. Even though the video quality is great and decent, stable shot can only be taken using a stand or a stable hand.

Software Interface and other features

The Galaxy M40 comes with Android 9.0 (pie), which is the latest interface of the android operating system. Moreover, on top of Android 9.0, Samsung Electronics has incorporated its skin called One UI. The main advantage users will have from the One UI is that it will provide a better experience of the Android system. Most of the text and placement of the content had been a shift toward the downside of the phone which provides ease to the users while using the tall devices. Moreover, those who prefer to use devices one-handedly, the interface provided by Samsung had made it comfortable to use as the controls, menus, and tabs which usually reside at the top of the phone had been a shift toward the bottom end which makes it easy accessibility.  

About the security, Samsung uses a fingerprint sensor at the back of the screen for unlocking the device. Which is quick and accurate. It would be great if Samsung had used an in-display fingerprint sensor but still features like having navigation gestures to control the notification panel, capturing photos using a camera app, and scrolling features that make it worth to have a faster and responsive fingerprint sensor at the back of the phone. Additionally, the face unlocks feature is available to quickly unlock the device. It is reliable and pretty fast but is not as secure as a fingerprint. Moreover, at low or no light condition this feature does not work. But during the day-time, I personally prefer to use the face unlock feature.

The non-removable 3500 mAh capacity battery is embedded inside the Galaxy M40. Compare to the size of the phone and the battery capacity used by its competitors, its battery seems slightly smaller. But Samsung claims that the battery optimization feature and efficient power management technology will allow the phone to be used for all-day. The average screen on time is about five hours while setting a medium brightness level. Which might vary with users to users based on usage patterns. 

Galaxy M40 provides 15 W fast chargers with the box, which is reasonably faster than the previous generation smartphones of Samsung. The device can be fully charged in about 96 minutes of charging time. For heavy users who spend lots of time playing games and watching a video in a smartphone, frequent charging of the device might be required.  


In a nutshell, Galaxy M40 is one of the best mid-range smartphones you can find in the market which has better value for the money. With an attractive design, better performing hardware, triple rear camera and Price tag of Rs. 29,990/- A large number of users had been attracted to it. But we can not assure you that this is the perfect smartphone for you to buy. Some of the compromisations Samsung Electronics made while making this model are the use of TFT panel for display which is of good quality but not as good as AMOLED panel. Similarly, 3500 mAh battery capacity is slightly inadequate compared to the recent trends. Besides that, the removal of a 3.5 mm headphone jack shifted users to use either wireless headphones or use Type-C connector. But personally I loved using this phone and recommend other customers to have it too.

Furthermore, If you are looking for an alternative device, then Redmi Note 7 Pro, Mi A3, Galaxy A50, Pocophone F1, Oppo A5(2020), and Huawei Y9 Prime are some smartphones with similar specifications and prices. You can also check the Samsung smartphone prices in Nepal and Samsung Dashain Offer
