Mr. Ajmera's Review (A business user)

Although the Karbonn K440 might be extremely portable with its small exterior but I don't think it's worth against the cramped keypad it offers and even the functionality isn't worth the struggle. With all the advanced call management features present in the Karbonn K440, it is good choice for business users like me. Bluetooth for file sharing is really not of much use to me, but this feature is really handy when it comes to hands-free calling.

Mrs. Iyer's Review (A homemaker)

It looks really small and comfortable for carrying, but I can't type without misspelling the words at least 3-4 times, that's how uncomfortable using this Karbonn K440 is. Video recording is a must on my phone, I just love recording and capturing the innocence of cake cutting or the craziness of a dinner party. I won't worry about the other features in the Karbonn K440 as the camera is so average and a strong deterrent for me. The expandable memory of the Karbonn K440 is a good option for me as against the high priced smartphones which come with high internal memory.

Ishan's Review (A geek)

As a smartphone, the screen size of the Karbonn K440 is quite decent; but too tiny when it comes to gaming or reading. Extendable memory is always a great storage backup if you have a growing collection of ebooks, games and apps.

Prachi's Review (A social butterfly)

The first thing I noticed in the Karbonn K440 was its 2.6 inches display. The screen size of the Karbonn K440 is too cramped and so I can't text that easily on this screen size. The Yes, 1.3 MP camera resolution is not that cool. You can easily opt for any other smartphone with a better camera, it might even be cheaper. I don't think this smartphone can click awesome pictures, which by the way is my favourite hobby.
