Voice quality during the call is very poor. Sounds Robotic and its really hard to understand the caller. May be due to on display earpiece. Very bad experience. Moreover one cannot replace or return the item. Amazon is not letting to do so.

Camera is very poor , the color is quite artifical , its better to buy samsung A-50 , now i am not able to return the phone also because of the phone poor performance.3 gb ram is used by system , so only 3gb remains for you.

Phone looks good in camera, touch, performance, battery performance is poor with 3500mah and on screen speaker vibrates a lot and bad voice clarity... Music with Dolby Atmos it's great.

Poor battery backup. With minimal WhatsApp and calls battery drained out in 7 to 8 hours.On call extra bass is noticed and the backside case I can feel that

I got this phone as a gift. I like the overall design of the phone and it feels like a premium phone.But when I use the camera on this device, I see flickering of the screen and it is extremely evident even in the video playback. This is ridiculous when you are marketing this device with one of the USP being a great camera.Now, I understand that some devices may be faulty. But the return experience should be seamless for the users. When I called Amazon, I've been told that someone will need to come inspect the phone and then decide if they will replace it. I find that very annoying again. Why should I wait for a replacement when something is evidently wrong with the phone? Can I just not send a video of using it to prove its faulty?User experience is not what I imagined it to be. Unlke in USA, the service here is lacking by Amazon!

Don't buy this phone only design is good, othr than that not upto the mark, camera also not good

I was quite a excited to buy this mobile, unfortunately this one has battery and performance issue. Worst thing is battery it drains so quickly.. 100\\% of charge doesn't come even for half day. Very disappointed..

The in call speakers is waste...call audio clarity is very poor, felt vibrations during call in ears...very uncomfortable to make calls....making calls is the basic functionality of phones and Samsung M40 has messed it up big time...looks like I have wasted my money

Look wise Its gorgeous from back,but display not up to the mark , there are few pros but lots of cons ..Using this device from 3 days now ..Cons ..1.Display not upto the mark*If you notice there is lite visble vignating spot around the punch hole edge ,2. SD675 disappoint me moreAlthough performance wise its decent no lags but in terms of gaming (PUBG) it perfrom horrible , in defult setting there is visible lags lots of frame drops , even lags are visible in most lowest setting , its horrible experience , even my Sd660 perform more better than this with HDR ,3. Both cameras are lacks detailing , specially in moderate and low light conditions,4. 3500 mah its topically generic 3450 mah , taking around 1.5 hour and more to charge , backup also fair (15-16 hours apporx ) with dual volte standby , gaming and other using5. No headphobe jack Pros ..1. Gorgeous looking from back ( sea water blue )2.wide angle camera lens

All looked fine but I finally found speaker is problem.Speaker has some big zz noise.I will check whether repair is possible at Samsung service.If not I have to replace or return...
