I brought the sony ericsson C510 mobile on 7th july 09, at the time of buying they actually compared the Sony Ericsson K810i with the sony Ericsson C510 they said it is updated version of K810i all the features are really good even the camera quality but when i brought the mobile after hearing from them i started using it for a day and then i took photo during dark surprisingly the picture i got is so pathetic that I am not able to see any image in that even after turing flash light ON. And when i approached the customer centre regarding this they say the camera quality in the night is not good in all the C510 phones so we cannot do anything then i asked them xchange phone or else give me a option to choose different model they are not at all ready to do any thing..
