By the way my phone w550i is 1.3 megapixel cam not sure if cmos type but it is cid 49 db2010 R4CB020. SOmeone has made a driver that has good colors and good in dark but didnt continued it, the problem wth the driver is that its too dark. though grainless but too dark. the original one is somehow dead in colors oh my but the modified one is alive but dark too dim hope you can make a good driver cause many w550i/w600i users are being left out in modified drivers
