karbonn A12 star - pocket me rocket hai ---updated

( 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...

Nice Phone at this price

Frankly saying...that's more than what you can expect from a 4k phone. Nice screen resolution, descent camera, good processor speed, no lags, no hangs, superb internet browsing speed and average battery life. What more we do need?
Recommended strongly!

Worst decision I made

I am waiting for Moto X+1. But the phone I had completely died and I bought this phone for temporary use. Been using it for the past 10 days.

About Flipkart:
I got it delivered within two days. I was unhappy with the packing. I am a regular customer of Flipkart and things I bought before always came with a good packing. The packaging was not up to the "Flipkart Standard". And the seal was slightly broken in the box. Might have been used before.

About Product:

First thing I have to mention ...

Great phone for this price. Camera is fixed focus one

I ordered this phone and i got it within 3 days. Quick shipping. Value for money. The only negative side is that the 5 megapixel camera is fixed focus one and the camera quality is not so great. We can't expect all to be good for this price also. Smooth operation and works without any lag. Good effort flipkart and karbonn.

Plz remember this is a 4k phone

Buying a smartphone at this price range is always a gamble and you never know what will come up in your delivery box. I was quite prepared for this and kept my expectations low. Luckily, my piece functions just right.

- Pricing is perfect
- Comes with some pre installed apps so you can start poking around immediately.
- Charges to 50% in 1 hour and 100% in 3 hours.
- Lasts 4 hours when used very frequently with 3-4 apps

- Camera is a complete sham, 2MP being marketed as 5MP. If ...

Good smartphone at budget price

Unpacking experience was very nice. This phone works smoothly and touch screen is very nice and smooth. Sound is not too loud but is good fora normal guy. Earphone quality is not good as expected, average earphone. Camera works excellent in daylight but for indoor use, it is not satisfactory.
Overall, if you are looking for a cheap cost phone, you may buy it.
