Karbonn A21 Review


There are many companies around today that try to fight it out for making the best phone for the lowest possible price. It is not hard to accept the fact that yeah it does somewhere miss out on quality but believe me they all are really powerful and amazing phone with decent qualities. Karbonn is one such company that are making such phones happen and doing wonders with them. Karbonn A 21 is a thing of good hardware for a lesser amount of price. It was up ahead with the Micromax A110 Canvas 2 when it released and it did pretty well.

Karbonn A21 has a very simple design. The phone has the most basics of shape, curved around the corners and flat out on the back. It is a little, just a little curved on the back to give you a good hold on the phone. The matte finish on the back is a good touch to the phone, it does not make you feel like you are holding something on the lower end price tag side but the front is a little too weird to not make you feel that. The front of the phone has this cheap looking plastic that goes around the edge and the screen (switched off, not the display) does not look good at all with an old television like screen colour. It comes in two colours- Pearl White and Black. You can choose this phone over Micromax’s A110 Canvas 2 for one reason and one reason only, the size i.e. if you prefer a smaller phone.


The display on the Karbonn A21 is no great. It is a 4.7 inch TFT capacitive touchscreen display. Karbonn A21 has a display with a lower resolution of 480×800 pixels with a very less pixel density of 201ppi. If it does make you feel better, in looks the display on this phone is much better than what you would find on the budget Samsung phones. Karbonn A21’s display is quiet decent. The colours are really off. When you look at it, it does not give you click in the head locking your eyes on the device and keep it locked for you to cherish what you have. In simple words, not at all a very good display but “quiet decent”. Karbonn should have gone for atleast certain software tweaks that could have hid the pixilation on the simple UI at the least.


Karbonn A 21 has a 5MP primary camera and a 1.3 MP secondary camera. The primary camera is quiet decent for a camera that you have on a smartphone for the sole purpose of uploading over social networks. It cannot capture image in great detail, not at all. But for overall capture of things that need to be there, it does not do that bad a job. You cannot use it as a camera you would take all over your vacations but it is good enough for shots such as “just happened to be there” the right place at the right time sorts. We wish it would have a better sensor to get in more light at atleast the saturation levels right. The primary camera does come with a LED flash and can autofocus on objects. It can also detect faces.


Karbonn A21 comes with Android v4.0 Ice Cream Sandwich mobile operating system. It is not upgradable to Android v4.1 or Android v4.2 Jelly Bean. Android v4.0 Ice Cream Sandwich was a pretty major jump from Android v2.3 Gingerbread. The Android v4.0 Ice Cream Sandwich is more user friendly, it gives you more with the APIs as a developer. It gives you better quality of apps as a general user and overall it is just so amazing to have. The Google Play store is so full of applications you can go and explore. Thanks to Google many of the applications are available for free on the Google Play store whereas same apps would cost you on iOS and Windows Phone 8’s applications store.


Performance is THE comparison point, it gives a phone their make it or break it situation. Karbonn A21 has a Dual Core 1.2 GHz processor and a 512MB RAM enough to give the smart phone juice to run good number of applications without any problems. The lag in the phone would increase with the amount of memory you put in through the microSD (duh). Overall it responses in a decent time and does not cause much trouble during entertainment.

Memory and Data

Karbonn A21 comes with 4GB of internal memory which can be expanded to up to maximum of 32GB. It has a Bluetooth v2.1 and a microUSB to facilitate data in the phone or for pairing devices for different purposes. You have both the support of 2G and 3G networks on this smart phone by Karbonn.

Final Thoughts

Why exactly you should buy this phone? Well it has a decent “size” of display and has a good amount of power. It does lack over quality over things you would really consider like the usual overall built. But for the money, all that is worth having. You getting pretty decent quality, not top obviously but quiet decent for the features this phone has and the specification build up.

Karbon A21 is available for Rs. 7499
