I told you. I bought C6 the other day, because I went with the mentality of E72I. Therefore, I hesitate to buy C6. When I came back to watch the online reviews, there were indeed overwhelming bad reviews such as collapse, light leakage, loose back cover and unused batteries. I regretted it then. However, I have been using it for several days, and I don't think my C6 has any of the above problems. I bought the Bank of China. I bought it at the Nokia store. There is no panacea for mobile phones, so buy them if you like.
