Issues.

I am using this phone for 10 days now. There are many good things which people have mentioned so time for some real things.

1. The processor although "dual-core" is very sluggish. You install a live wallpaper and the phone starts to lag.

2. Cellular signals are not very strong and they keep coming and going.

3. Phone charging is fast but discharge even faster. Currently I need to charge the phone twice a day if I am using data connection/wi-fi for around an hour.

4. The charger pin is har...

Nice phone at such a low price

Hi friends,
Purchased this phone on 22nd Oct 2012.

Read many reviews on the phone, few were good and few bad.
Let me tell u something, at this price if people compare it to Galaxy S3 or Note then they are the biggest fools (Sorry for being rude but I don't know why people compare it with phones costing above 20 or 25K).

Now coming to the phone's features. The specifications provided on the website are absolutely correct.

1. It comes with a 1.2 GHz Qualcomm Scorpion, Dual Core which is very...

Amazing phone: worth it even at double the price

I've used HTC, Nokia and Samsung phones before this and was a little afraid of committing Rs 10,000 to a budget phone brand. But my fears were completely misplaced. This is a great phone with absolutely flawless performance and finish.

I've been using it for three days now, installed a lot of apps, watched videos, played some games. If you were watching carefully, some animations may be slightly jerky compared to phones that cost 30,000 or more. But at this price, buying the A21 is a no-brai...

A fair review..you can count on it..!

Okay..I got my A21 today..I have been playing with it for sometime now..I didn't get it from Flipkart..but trust me the phone is awesome..As seen in Igyaan video..it lags during live wallpaper and trust me it must be some technical glitch because as soon as I install Nova launcher..It worked so well using live wallpaper too..
Music is nice..Not BAD AT ALL..but don't expect it to be of Beats level or something

Gaming is good..Runs temple run smoothly..and Subway surfer( most famous now a days...

Best mobile in the medium range segment

I can say that if you have the bidget of 10K that just go for this mobile eyes closed

At first it was so hard to believe. How can we get so much more at such rock bottom price. I am sure many users will think like me.

But then I saw some hardware tests on iGyan with benchmarking tools like Quadrant and NenaMark. After much deliberation. I decided to take the risk and go for this amazing device after all it only 10k which i was spending.


My brother owns a recently purchased sony xperia neo...

VFM Bought this over Micromax A110

i have hands on tried both Karbon A21 and Micromax A110.

i choose Karbon A21 over Micromax A110 because-

1)Build quality of A21 is better
2)Display of A21 is better than a110.may be it is due to a smaller screen but to tell you the truth it was at par with samsung phones worth 15K (that was a big reason i bought A21)
3)Touch for both was quite ok , still i feel A21 was much smoother.
4)Both are dual core and have quite similar configuration so there isnt much to compare on the hardware side...

its main merits are(in my view)
1.Qhd resolution with 240ppi(it is amazing on direct view with auto bright)
2.4x6, ie; 24 icons per screen menu(other's only 4x5)
3.Smooth play back of 720p HD(1280x720) videos(smooth random seeking,stretching etc. all funcntions of MX player)
4.Data on both sim are good and easy switching(auto) when data not available on one sim
5.SAR value of 0.437
6.Quadrant score of 2709(above moto atrix 4G)...

Why Karbonn A21?

Dual SIM users.... Say big "NNNNNNOOOOO" for Karbonn A21.

I have bought twice Karbonn A21 using replacement option with flipkart. Finally it fails to satisfy the Dual SIM option. Tower pulling is very poor in first slot. Most of the time others will get "cannot be reachable" response.

Apart from that....

• 1.2 GHz Dual Core Scorpion Processor - Good.
• 5 MP HD Primary Camera - Not up to the mark.
• 1.3 MP Secondary Camera - Okay.
• 4.5-inch Capacitive Touchscreen - Good in feel & fast res...
