Samsung Galaxy M40: Design and Punch-hole display
The Samsung Galaxy M40 is company’s first affordable smartphone to offer punch-hole display. In my opinion, it’s the best design I’ve come across from Samsung in a long time. The phone fits and feels really great in hands. It is quite lightweight and I would not mind the polycarbonate body over the glass or metal, if that keeps the weight in check. I didn’t get to review the Seawater Blue color variant, but that’s an extremely good-looking phone over the Midnight Blue.
Upfront, you get a 6.3-inch full-HD+ TFT LCD Infinity-O or punch-hole display, which is nice and bright. The touch response, color reproduction and viewing angles are decent on this display. The bezels and bottom chin is fairly minimal, and doesn’t look ugly. Also, the front camera punch-hole is very tiny, and the overall design looks like a premium flagship phone.
Samsung Galaxy M40: Camera performance
At the back, the Galaxy M40 packs a triple-camera lens setup similar to Galaxy A70. It consist of a 32-megapixel primary sensor with an f/1.7 aperture, a secondary 8-megapixel ultra-wide (123 degree) angle lens with f/2.2, and a 5-megapixel f/2.2 sensor for depth. Sadly, there is no Optical Image Stabilization (OIS), but you can shoot video up to 4K at 30fps and 720p slow-mo videos at 240fps.
For the front selfie camera, the Galaxy M40 uses a 16-megapixel f/2.0 lens, which is being position on left corner of the display. It is quite tiny and doesn’t look distracting on the display. Talking about its performance, it takes good selfies and retains the natural skin-tone. The ‘Live Focus’ bokeh mode lets you set the blur intensity, but the edge detection isn’t great.
Samsung Galaxy M40: Battery performance, Fingerprint sensor and Face Unlock
In the battery department, the Samsung Galaxy M40 packs a 3,500mAh battery with USB Type-C and 15W fast charging support. During my review, the M40’s battery backup was mostly good for a day. My usage pattern can be considered as above average, but not extremely high. It included web surfing, phone calling, bit of video streaming, maps navigation and social media apps. The phone doesn’t heat much and the battery doesn’t get drained too quickly during navigation.I also found the battery charging to be reasonably good, but not that fast. It usually took about one hour 45 minutes to full charge the phone from 0 to 100.
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.
