Rear Camera 4/5 4/5 Flash 4/5 Front Camera 2/5 not as per 2 MP. Touch 4/5 Loud Speaker 5/5. Voice and mic 3.5/5 Battery 4/5 (Female use) I first bought Huawei Honor Holly gift it to my Wife. Due to display issue in 3 piece i go for Karbonn Sparkle V. Price difference 2,000, with this access Rs. 2000 i bought SD card of 16GB. Two dress worth of 750. All r happy now....

Pros: 1. Clean OS. No bloatware. 1 GB RAM feels sufficient because of this. 2. Latest Android Version. I got Android 5.1 much before other flagship phones. 2. Fast. Mostly lag free. 3. Good Front Camera. Even better than my HTC One S. 4. Average Battery Life. With 2 hour screen time, I get close to 20 hours battery life. 5. Light Weight and Compact. Easy for Single Handed Usage. 6. Supports 32 GB memory card easily. Good for photos, music and offline files. 7. Dual SIM. 8. Loud Speaker is pretty loud. Makes look my LG G2 and HTC One S like a kid. Alarms are hard to miss. :) Cons: 1. Low Memory. Out of 4 GB, you get around 2.2 GB. After using it for 3 months, having installed around 15-20 apps and application cache getting accumulated, the phone ran out of space. By default, the apps gets installed on Internal memory and no option to change this. I manually moved the apps to SD card. Not all the apps can be moved to SD card. And, still, only part of the app moves to SDC card. So, this is the biggest bottleneck. 2. Average Rear Camera. Even day time photos are hit and miss. 3. Low resolution. In many apps, you have to scroll to fill even if the form has 4-5 text fields. 4. Accessories are hard to get. Even in Flipkart, Online and Offline stores, you can't get even the basic accessories easily. One consolation - Micromax A1 cases fits this phone though not perfect. 5. When Flip Cover is used, Proximity sensor does not work. I checked 2 cases and it is the same story. For the amount paid (4k), it is a good value for money phone. If the phone had 8 GB ROM, I would say the Android One series phones are best phones under 5k range.

I Purchase this phone 5 months back. This is really a Nice Phone. 1. Worth for Money. 2. Lollypop Operating System is really great. 3. Updates for the phone i.e., for operating system are really up to date. 4. Android One phones are really unique than other normal android phones. 5. What ever google releases will be updated to your phone instantly. 6. No Strucking, No Bugs, New Features, New Look 7. Decent Battery life for a day with 3G/WIFI Cons: 1. Very low internal storage - Now a days android application are large in size, you can load more apps into this phone. But loaded apps will work awesome.

Now this is a nice phone.. I bought the Lava IRIS Atom 2 and faced all kinds of problems.. The Spedtrum processor sucks... And the phone heats up like heck... But the Sparkle V maybe cause it has 1 GB Ram and a Mediatek Processor.. It breezes through multitasking.. Games.. HD Films.. Nothing is a problem....maska smooth.. No issues.. No lagging no freezing... Yes storage is an issue.. But you can always use a memory card.. And the screen quality could have been better.. But for the price it's well above its competitors... Good Going Karbonn..

Using it for almost 2 years, yet not even a penny have I spend on this Karbonn A1..As good as new..Still loving it..Can handle almost everything that a high end device can do...Even, I'm writing this review through the same one....You'll all the latest updates of Android as soon as they arrive in the market(Release)...good for Game addicts...I have played numerous games which ran flawlessly on this device...Must buy if your budget is low....

I am extremely happy for the super fast delivery of flipkart & the behavior of courier boy.& the mobile is really nice according to money.

Satisfied with what features it has for just under Rs.4000/- I have been using this phone for the last 15 months and I have never encountered a single problem... I upgraded it to 6.0.1 Marshmallow... And system updates also works smooth... When coming to battery you have to adjust a little... Battery backup is not good only 1700mAh capacity...

1 have used this mobile for more than 1 year and trust me in 4k u cannot get any better phone from this i buyed thhis phone for 5000 but still satisfied. it is upgradable to marshmallow 6.0 , has pure stock andriod, and one of the best 5mp camera in 4k.just buy it trust me u will thank me.

I've been using this for like 5 months now.I have really enjoyed using this device. I got the device with Preinstalled Kitkat. I have tried : (kitkat) 1)lollipop 2)marshmallow (I was stuck with boot animation when i tried to to root it later) 3)Cyanogen 12 (battery problems) 4)Pac-Man rom (The best custom rom) The product is awesome inside but I did not like the look(personal opinion)
