Lookwise and Operation wise superb phone.. Operates smoothly with sanpdragon.. Display is awesome specially with lighting around front camera... holding in hand gives super premium feeling.. I didn't like the camera quality at all.. bokeh effect pathetic even in full day light... low light photgraphy at night not upto the mark... Except camera outstanding phone...After 7 days of use... Notification a big problem. You can't even turn off.. I get some useless notification 3-4 times in a day and there is no option to turn off.. Can Samsung Justify why you don't give option to turn off???

Lousy product and lousy after sales service by Amazon. Pls don't buy, just bought a new mobile m40 and the sim slot is jammed and doesn't open. On calling Amazon I was enlightened that the guy attending to my call is the final authority and that I can't put me.on to anybody higher up.( this is on record). He suggested that they merely sell products and any defect is not their responsibility. He offered a solution that a technician will visit me 5 days later check the device and then draw up a story, post that they may replace the product. And beware there is no refund. Such pathetic service, they are taking us for a royal ride. He went on to say that they only promote products and give two hoots of what quality that product is off. So anybody who bought this..your problemo, you have been conned.

20k waste one of the worst mobile. They gave lots of adds for this mobile. After bought samsung cheated with fake features. Not worth for 20k. My money lnly wasted. If i seen this mobile in showroom i never bought this only.

Camera quality very worst and pathetic.Battery life average only and draining fastDisplay quality looks like 5k smartphoneLow sound effectsVibration in screen during calls and it is not clearTotally disappointed with M40 and want to throw back in dustbin.

Waste mobile camera is not clear picture

I have purchased this product in the first sale but the mobile is Not a good one camera performance is average and it's too sleepri. The screen sound technology is not so good. I have purchased the product after watching so many review from youtube but they may be paid reviews. Disappointed with the phone.

Display is awesome, punch hole camera gives premium look. Back looks cool. Overall good product. Value for money. 😘

The voice clarity is not being reproduced well and even in slightly noisy environment its difficult to converse without asking the person on other side to repeat a few times.Battery doesn't last even a day

Very poor battery.

Don’t purchase it’s was of money
