First of all, Thank You Flipkart for delivering the product such a short time ('cause I could hardly wait to get my hands on this device). Coming to the handset, lets tell you guys about the pros first.
Pros: 1. Excellent ergonomics and very lightweight.
2. Super Amoled Display with 301ppi resolution.
3. Pretty Good Camera for this price (low light pictures are not so shabby like other devices in this price range).
4. CAME WITH ANDROID 4.4.4 KIT-KAT PRE-INSTALLED...

Its been just a month I have bought this mobile from Flipkart. Apart form the recent 'lollypop' upgrade, this mobile gives almost all you wish for at such an affordable price. RAM (1.5GB), processor (1.4 GHz), storage (16 internal, expandable upto 64GB) & camera (front 2Mpx & rear 8Mpx) makes it any time an above average mobile phone. The body to screen ratio is apt., just the way I wanted.
I am pretty happy with this handset!!
Let me tell you all, I was't a Samsung fan at all, but now its ...

Samsung Galaxy S3 Neo Dual (GT-I9300I) is an excellent device for low budget smartphone lovers. For those who prefer super AMO LED display ,great processing speed in a less than 5 inch screen size, More interenal storage(16GB) Details cut short, this is an outstanding choice for its monetary value.

Very nice phone, i am giving my view after use of almost 1 month, Everything is ok in this phone, It has good battery back up, back camera quality is good, but front camera is disappointing, in feature it shown 2 mega pixel but it seems VGA. Sound quality is good. Thanks flipkart for fast services.

i purchased just 15 days back the cmera is good ,the processor and Ram is good it is light weight and slim the storage capacity is also good it is a value for money product

I Would Like to give 5 ***** Star to flipkart- Original Product, Fast Delivery 24x7 help for customer. and I would like to give 4 **** Star for samsung Galaxy SIII Neo- Very nice Phone Look very good, Performance is very fast, Video quality so good (excellent) but Sound Quality is not good. and Battery is average. And over all is so good.

Super phone for 12.5K fabulous camera and battery back up is awesome people who is writing that it has a problem for heating up and battery back up I must say its crap, must say go for this blindly and buy it from Flipkart itself super delivery experience.

Its been about a week since I received this goody.
Delivery was prompt, as I opted for Rs.90 extra In-a-Day delivery. However, I feel, it would have been delivered by the same time even without paying extra for the faster delivery. (As WS Retail is a flipkart advantage seller).

So far, all features are working fine. Some insight:
1) No heating problem as such. Though I am not a gaming enthusiast, the handset goes without complain with moderate calling/texting/mailing and mobile data, bluetoo...

I have samsung galaxy s4 and bought Samsung S3 Neo for my wife. She is using this phone from last 15 days.Let me tell you one thing there is no difference in between s4 and s3 neo looking wise.Beside this 1.5 gb ram is more than enough to play heavy games. Camera quality is good but if i campare it with s4 then obviously thumbs up for S4.
Now let me talk about battery life...S3 neo battery backup is far more than s4. I have never seen a smart phone which can stay away from his lovely charger ...

Good Product but little costly!

high performance Touch screen with very good clarity. works best even when battery is very low. must buy if u r looking for something that works and suits you best.
