I am using this phone for 10 days now. There are many good things which people have mentioned so time for some real things.nn1. The processor although "dual-core" is very sluggish. You install a live wallpaper and the phone starts to lag.nn2. Cellular signals are not very strong and they keep coming and going.nn3. 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.nn4. The charger pin is hard to remove and if you try to force it out, the plastic back also comes out along with it. The back does not fits completely and there is considerable gap in the sides.nn5. If you are using your apps in USB mode the touch starts to act funny(maybe only in my case). You touch somewhere and the response comes somewhere else. You try to open one app but another one opens up.nn6. The front camera although is 1.3 MP but the output is very sluggish. nn7. The rear camera is good but if you try to take a panorama shot, the image is blur and jumbled.nn8. The phone is not playing any video which is above 20 mb in size. I tried playing the videos through MX player but they just do not run.nn9. RAM is 512 mb however the phone is not running any HD game.nnSo, make a informed decision.nnThanks.

"So far so good"
27 Oct 2012 By N Shaji On flipkart.com

I have gone for this phone because of its features and its price advantage. One month back I bought Sony Xperia P for one of my family members. After spending Rs.23,000, it still gets stuck while opening the Gallery and the Maps. Every time I need to restart the phone to get the Gallery open. If the performance of a phone of Rs.23000 itself is like this, then I thought that, nothing is wrong in buying a phone with better features at lowest price. So I decided to buy Karbonn A21 for myself.nI got my Karbonn A21 through Flipkart yesterday. Let me review about the Pros and Cons of this phone by comparing with our Sony Xperia P.nPros: n• Wide Screen display of 4.5” against 4” in Xperia Pn• Slimmer than Xperia Pn• 1.2 GHz Dual core processor against 1 GHz Dual coren• Internet connection through Wifi Direct is faster than Xperia Pn• 12 Hrs continuous battery life while browsing against 5 Hrs in Xperian• Phone comes with scratch guard film fixed and one additional film in the boxn• Dual GSM sim card facility against single GSM simn• Equally good touch screen display and graphicsn• Camera quality is equally good although it is 5 MPixn• Lesser SAR value than Xperia Pn• 1.3 MP Secondary camera against 0.3 MP in Xperia Pn• Normal Sims against Micro Sim in Xperia.n• Battery can be removed, against inbuilt in Xperia PnCons:n• Weight of 130 Gms against 120 Gmsn• Back Cover looks flimsyn• Even though screen display can be compared with xperia P, touch response of A21 has a lag of fraction of seconds.n• Charger adopter slot in the phone is very tightn• No HD video callingn• 3D sweep panorama in camera not availablen• Although face detection is available, smile detection is not availablenGeneral Satisfaction level:n “ All is Well” in both these phones, Except “Price and Fame!”
