This blog is for those of you who are tired of going through all the reviews and comparisons and still thinking -' which one to pic?'. But if u still want to go through the specs ,u go to the links given at the end of this blog.
Both the ninja and s duos have a similar design ,but s duos fells better in the hand an feels solidly built . Ninja on the other hand feels plastiky and cheap. Coming to the display ,the ninja's display with the same resolution comes no close to the crisp display of galaxy s duos. The touch response of s duos feels more fluidic .Both the phones have an average readability in sunlight. The UI of ninja is stock android .S duos runs on the 'touch wiz' skin seen on other samsung devices . This makes the device slow on multitasking . Ninja has an upper hand over s duos because of its stock interface and it feels very fast. The camera of s duos performs well in well light conditions whereas the pictures taken on ninja were grainy and the colors felt washed out.In dark conditions s duos performs better because of the presence of the LED flash . The video quality on s duos is good and that of ninja is poor. When it comes to performance , ninja equipped with a dual core processor performs surprisingly fast .S duos lags on multitasking. The music quality on s duos is the best . Not only does the music sound crisp and clear ,but also the wide variety of equaliser options are a boon. The virtual 7.1 feature is a big USP of the device.Music on ninja lacks bass and the stock headphones provided are of poor quality.
