Dual SIM : Am updating the dual sim feature after using it for a while. The DUAL Sim feature is a junk. Ideally if I have two sims I should be able to receive and make calls on both the numbers based on my choice. But Samsung has got it all wrong. The phone lets you set one of the SIMs as the DEFAULT (and you always need to choose one). This essentially means you can receive calls on both the sims but while making calls it uses the DEFAULT sim, even if the call came on the other SIM or the contact is stored on the other SIM. This applies to messages too. I am not sure if this is how dual sims are intended to work, even if thats how it is supposed to work, I dont think it is right, at all. The worst part is that if I have to change the DEFAULT sim, I need to restart the phone, its all crapish.
My Opinion: Reading the reviews here and at other places I blindly went in for C5212. I brought one the day before yesterday for Rs. 4, 500 /- in Bangalore. Overall opinion about the phone is that it is NOT ALL THAT GOOD.
Looks: Appears to be made of some cheap plastic, no appealing looks.
Feel: Pretty heavy for the supported features. And is big and thicker than my blackberry except for the width.
Ringer Off/Silencer: Ringer or silencer is missing. So you have to either attend or cut a call. You cannot silence the ring.
Camera: The image quality for a 1.3 MP camera is good.
Wallpapers, Themes and Ringtones : less choice
Keypad: is real hard, my thumbs are aching
FM Radio: Audio quality is ok. Most phones support wireless FM now, not sure why Samsung is still stuck with the earphone FM.
Games: Comes with two preloaded games, and not all the interesting (not addictive). You cannot play for long because the keypad is too hard.
Audio: Audio quality in handset mode is clear, while in speaker mode there is lot of noise.
Battery Life: Battery life seems to be good, I charged for only an hour on day one. It is still at 50% full.
You will find most of these features and more and better from other brands and at a better price. The only reason you should probably buy this phone is that it dual sim and it is from SAMSUNG (if you are a Korean or a fan of this company).
