Mr. Ajmera's Review (A business user)

A small device like this might neatly fit in my pockets, but that's all it can and nothing much with the cramped screen size of 2.4 inches. I more than often go for efficient devices like the as it present me with a robust call management; as I am hardly ever off my phone. Bluetooth in my smartphone is essential more for hands-free calling than file sharing.

Mrs. Iyer's Review (A homemaker)

I hate typing messages on the Karbonn K 4 with its tiny keypad as I misspell a single word more than 3 times. Video recording is fun and lets me record all beautiful memories of birthday parties and the energy and excitement of a house party. A smartphone without a good camera is really not my choice, even if the Karbonn K 4 sports other excellent features and fairly makes up. I will need to delete or transfer photos every week if I choose this Karbonn K 4 with its small storage space. I always feel the more the better when it comes to smartphone storage and I would always chose the Karbonn K 4 with expandable memory against any other smartphones that are overpriced and overloaded with confusing features.

Ishan's Review (A geek)

The 2.4 inch display may be quite decent for a smartphone but I don't like it for my reading or gaming purpose. Smartphone storage with such low capacity even for basic apps and programs is really irrelevant. If you have gaming and ebook library as huge as mine, you can never say no to an extendable memory storage.

Prachi's Review (A social butterfly)

The 2.4 inches display of the Karbonn K 4 was the first thing that grabbed my attention. I prefer texting over talking but this screen size is way too cramped to do that easily. It's not that amazing to own a smartphone with Yes, 1.3 MP camera resolution. There are cheaper options available that too with better camera resolution. I click hundreds of cool pics with my smartphone and don't think the pictures will be so cool with this phone. I don't worry charging when I can charge my phone with the laptop; I can even transfer files with this. The 4.5E-5 GB internal storage is really very less. If it can't save all my files then what good is it.
