Both the Smartphones are having same Java Operating system.
Both Phones are having 2MP Camera with 1600X1200 resolution with video recording of resolution 176X 144 @ 15FPS with no flash.
Now in this case Nokia C3 has got proper application installing and downloading feature with the help of Nokia Ovi Apps in which we can add applications to Micro SD card and download many apps easily but in Samsung Chat 335, they have their own app downloading site but has very less and worst applications, also they get downloaded to our internal memory and that too in "Games and more" folder where it cannot be renamed.
Here, Samsung Chat 335 wins the race with an internal storage of 60MB whereas Nokia C3 has got only 50 MB internal storage.
When I held both the phones I was experiencing Nokia C3 quite heavy. Samsung chat 335 was much lighter. By measuring both the gadgets weights, Nokia C3's weight was 114g and Samsung Ch@t 335 weighed 95g.
Well Samsung has been much concentrating in its design so as to make it much comfortable for using.It has also got a plastic texture at back so that it gets in the grip of the hand easily and also it will not get scratched very easily.Samsung Ch@t 335 has also got specially designed buttons which makes the user very comfortable to type.
While in Nokia C3 its design is not worth appreciating .It has got a simple plastic back cover with a glossy shine and its structure is not made nicely because of which after using for 2-3 months it gets filled with scratches. Buttons are little fluffed up but then also it cannot compete with the QWERTY buttons of Samsung Ch@t 335.
Both of the Phone models have got excellent connectivity with the WiFi but in case of GPRS Samsung Chat 335 is slower because it has got Class 10 GPRS While C3 has got class 32 GPRS. Well another thing which is most important is that YouTube does not run well in Chat 335 but C3 it runs good with the help of WiFi runs smoothly. But yes, on updating the OS of samsung Ch@t 335 via Kies it can also run videos from YouTube's website very easily.
Both of the phone models are having Li-ion battery but battery backup power is more in C3, that is
Chat 335 has got 1000mAh while C3 has got 1320mAh Power.
Nokia C3 Completely Wins this case because you have the accessibility to download and use themes as much as you like but in Samsung Ch@t 335 you can use only that type of themes which are provided by default.
If you are confused in deciding which phone to buy then according to me, if you are mostly interested in applications then you should buy C3 else, if you need a phone which is comfortable in typing,requires less maintenance and with a better nicer design then go for Samsung Ch@t 335.
