I have this mobile phone for about one month. It seems no sleep bug is often appeared in many posts. What is it? For me, I have found no bugs for this phone. Some people in China have the "drop off" bug. It means if some one call them they cannot answer because when they are ready to answer it, the call will be cutted off suddenly sometimes. I dont know the reason. However, I think the only "bug" for me is that it is SLOW. Even when I use the "auto memory management", returning desktop costs about 1 minute sometimes. Any one can help me to solve this problem?
