    Overall: ( Updated:- multiapp window open by double click home button, 2. Battery life increase by updating / installing OTA update )

    1. The only first thing i was disappointed to is camera flash is only for name, not works in dark.
    2. The battery drains "little" fast when using 3G, otherwise its very good backup.
    3. The charging of battery is slow 4. The manual in this box does not provide complete information.

    1. Performance wise is very good, speakers are also good, features wise the mobile is superb' and its look is great, the camera quality is best in daylighting.
    2. Some users say it has not GPS but actually when we using google map in this mobile, there is a option of GPS by which we can see our exact location.
    3. The others features its has dual sim, bluetooth, wifi, 3G, dual processor, GPS, FM, latest OS kitkat, Bright display, good battery backup.
    4. its has also included screen guard on it so its saves my penny.
    5. Surprisingly its has 1.3 GHz dual core processor.
    6. One very important thing is that its is the latest version of Karbonn A12 plus.

    1. Flip kart delivery is fast but packaging was quite simple.

    As I received this product today I.e 7 July 14, on my Di b'day hence the phone is in budget & the features of this phone is superb and I would recommended to others to buy this Smart phone.
