Samsung Galaxy M40

Samsung has added another member to its millennial centric M-series – the Galaxy M40. The new model was launched in India last week, and the big deal about it is its infinity-O’ display, which is essentially the punch-hole cutout on the screen to place the front camera without needing a notch.


Samsung Galaxy M40 has a 6.4-inch FHD Plus display with 1,080 x 2,340 pixels resolution and a pixel density of 403 ppi. The phone delivers an immersive visual experience. It has a 19.5:9 aspect ratio. The Galaxy M40 will come with an Infinity O display. It is reportedly one of the most affordable devices with Samsung’s punch hole display.


Once again the Galaxy A70 is from where the M40 draws inspiration. You will find a similar 32MP (f/1.7) sensor as a primary rear camera. The primary sensor gets the assistance of 5MP (f/2.2) depth sensor in portrait mode ( live focus in Samsung’s terminology). There is another 8MP sensor on the back that can capture ultra wide-angle shots (123-degree field of view).

Apart from these rear cameras, there is a 16MP (f/2.0) sensor for a selfie on the front of the phone.


The Samsung Galaxy M40 is powered by a Qualcomm Snapdragon 675 chip and an octa-core processor with Adreno 612 GPU that offers a smooth graphics experience. Coupled with 4GB of RAM the phone can handle most games and can easily multitask. Connectivity options included in the device are WIFI, Bluetooth, GPS, NFC, USB Type-C, and 4G. It offers an active noise cancellation with dedicated mic, and Dolby Atmos sound which enhances your gaming experience. The Samsung Galaxy M40 will run on Android 9.0 out of the box.

It has ab integrated fingerprint (rear-mounted) sensor, accelerometer, gyroscope, proximity, and compass sensors. The Galaxy M40 is packed with excellent features.


Battery life is one of the Galaxy M40’s strengths. The 3,500mAh battery lasted for a good 15 hours and 30 minutes in our HD video loop test, and with regular use, we managed to average a full day on a single charge. With heavy use, which included lots of camera and benchmark usage, we still managed to get almost 20 hours of runtime. The phone supports Qualcomm’s Quick Charge technology with the bundled 15W fast charger. We were able to get from zero to 47 percent in 30 minutes, and up to 86 percent in an hour.

Overall Verdict

This is a good looking phone with the hole punch display. They design is good minimal. This does the job of decent gaming. If looking for heavy gaming then should try the poco f1 or k20s these are a few bucks more to the budget. The camera is decent and performs good in daylight. Battery is another good thing about this device. The snapdragon helps it perform well. The another option is A50 if you’re looking for a dew drop style display there performance in both is quite similar.
