Wonderful budget phone that no other company is giving such features in that cost.
Good overall performance and never had any major issues in last 4 months..
Worst part is only the headphone supplied which did not work and unsuitable. The max sound in handsfree is very low that you dont hear anything during driving/travel etc..
If you are looking for a good feature phone with max benifit at low cost, this is the one.

I bought this phone for my father as he wanted a touch screen phone. It seems to be qite good for its price. My father is an infrequent and cautious user. So the phone is in ship shape. The camera is not very good but then its a budget phone after all. The screen is nice and responsive. It has got android jelly bean which is quite smooth.
Overall a good phone for its price.
Flipkart's service is quick and dependable as ever.

Perfect for the price range. But much better phones are out there if you're willing to spend just a bit more. The earphones are the only disappointing part. You might as well throw them away :)

Pros :
Battery backup good...
Able to see in sun light.
Flip-kart delivered in time.
Icons are sharp.
Using for 1 month- every thing works fine.

Cons:
No GPS. A-GPS- not showing exact location
Camera not Good - don't buy this mobile for camera

I brought this device in december 2013. Since then every person whoever saw this device thought it is lumia, sometime xeria.... A great hifi to those who were lucky in getting this device... Since it is now been discontinued..... It also support almost all games, tweakz & lots more...... ATLAST GREAT THANKS TO FLIPKART FOR THEIR DELIVERY WITHIN 1DAY & KARBONN TO LAUNCH SUCH A GREAT DEVICE..... those who missed this mob can get xolo a500s.... same spec as A12+.....

Karbon a12 + is a Good phone.According to cost but some features is not gud like Camera is good in daylight but at night flash is just a tourch.

Has all the features, good display, camera is also not that bad.. overall good phone at such a reasonable price. Flipkart service is just amazing.. hats off guys...

Had used the Karbonn A9+ for four months and it was doing well before it was lost... So when I ought this phone I had similar expectations... The price point was really very attractive...
Everything that a moderate user would want is available and does very well too.. other than
the camera (bad) and music (just about ok as the inbox headphones are very ordinary)...
The touch, visuals and app performance is all very satisfactory...
So depending on your priorities... this could be a very good ...

Nice product within budget price. Nice service by Flipkart. Proper way to track your product.
Oveall satisfactory and all is well.

Nice Mobile....But low quality headset....low price but performance is good...it is better than xolo a500s and samsung s duos....just 5k smart mobile....no heat...all games will be play...hd songs will play without any lag...
