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.

Less RAM,Processor speed. Samsung is cheating Indian People with a phone with less features than the previous version. Applications are not running properly.

i am using this mobile for Three Days First Day it was ok Second Day i started downloading apps especially Facebook. Third day the Processing mobile is slow and i cant open any app when i Open it it response only after few minutes some time it is not responding Battery Back up is worst now I have clicked the return option waiting to return the mobile

I bought this phone for Rs 7500 from local retailer on 26th sep, 2014. My father is using S duos 2 for 7 months, so i decided to buy this phone as the performance of s duos 2 is just great. When i unpacked it getting the first shock, sensor is missing.. After switch on the mobile i got shock shock shock..... poor built quality, bad camera, poor sound. Heart broken.... Better to spend on Motorola or Nokia... Dont buy this crap....

bakvas hai ye phone.....i thinks same segment is good but this phone is very slow performance, ram is 512mb, so not good this phone....

Original product using since 2015

Worst product , Hanging always

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.
