I thought that successors were upgraded models. Turns out I was wrong. RAM has been reduced to 512 MB (Duos 2 had 717 MB) and the processor is just 1 GHz (Duos 2 had 1.2 GHz). Add Samsung bloatware to the plate and you have a phone that a tortoise can outrun. Only advantage is the KitKat OS but I have seen people change the launcher to Nova irrespective of the TouchWiz version available because they just cannot stand the cartoony offerings of Samsung. I wont say any more. You decide for yourself... ;)

Pros Compared to Duos 2 : 1 >> Much Compact and feels better in hand. 2 >> Improved Touch. 3 >> Camera to is better. 4 >> Latest Android Kitkat 4.4.2 OS. Cons : 1 >> Reduced Processor from 1.2 GHz to 1 Ghz. 2 >> Reduced RAM. From 712 MB to 512 MB. 3 >> Removed Proximity Sensor. Buy it if you missed buying Samsung galaxy Duos 2. Else there are much better Options from Micromax and Xolo in Same Range.

Don't ever buy this phone If you want your phone to be very fast and do your work on every single touch, then this phone is not made for you. If you want to waste your time and sit back and relax after every touch, then yes it is the best choice, GO FOR IT!!!! SAMSUNG has brought a new technology named TOUCHWIZ which helps your phone to become very slow. Choice is yours.

I was recently using the micromax bolt A65.There were more cons then pros in that phone.No doubt that it has various 3 sensors but what's the use if the phone lags??? The camera quality was also not good and the internal memory and its operating version the 2.3.5 gingerbread...A shit! I was fed up of that phone and exchanged it for a brand new SAMSUNG GALAXY S DUOS 3.I did not buy duos 3 from flipkart.I am pretty satisfied by this phone.Various pros such as 5 mp autofocus camera with a flash,the front facing vga camera,operating system Kitkat 4.4.2 are great.The phone is pretty fast and looks good with a white colour.Feels good in the hands.Do not worry about not having a proximity sensor....the phone will lock itself so good that u will not feel the need of having a proximity sensor.I recommend this phone to everyone.

I used the phone... For 3 years great product from flipkart...it was a great experience and i always love to buy products from flipkart..

Samsung Galaxy s duos 3 is best compatible price value phone. I can use 2 year nothing any problem no require any service and battery is good and this is 3g phone.but today markets price is very high compared me buying time. Samsung mobile is best forever.

The most amazing feature of this phone is that it runs on android 4.4.2 kitkat means you can run all the apps. The touch response of this phone is also very good. Also it has 4 gb of internal space and 512 mb ram. I have enjoyed a good speed internet on this phone and also played some games without any lag. The back camera is too good with the flash and the front one being 0.3mp is also good. The overall performance is good but when we compare this to S duos 2 we find that the processor and ram has been decreased. Its not a bad phone so I'll suggest you to go for it .

Very nice mobile past 4 yr above I'm use this mobile. I love it... It's very nice .... My child use this mobile ruff and tuff useage. No any damage.. Good I'm very happy to say.

Phone is pretty good and quality built. The specifications are pretty ok for minimum usage (just a few apps and not gaming or any other heavy usage). Happy with the phone and flipkart services.

Amazing Android with awesome Camera=Full Value of Money!! No need to waste time to check gimmick such if it has Dual Core or not, or it has which RAM, It is a nice and easy phone for daily quick life style. Thanks Samsung ! Thanks Flipkart !
