I tried very hard to get Android DDMS(Debug Monitor) working. It cannot detect my new phone(Galaxy S). Moreover, my computer kept to say "SAMSUNG_ANDROID" driver missing. No surpising, the computer cannot recognise my new phone. As a result, Android DDMS(Debug Monitor) cannot connect to my new phone. I was trying to search for the "SAMSUNG_ANDROID" driver,but no lucks at all. Well, I know Samsung has a software to desktop synchronization, Kies. Maybe, it can help. After I installed it. All driver problems are resolved! I can use Android DDMS(Debug Monitor) now.
