I am Karan from Mumbai
The 551 fails to be recognized in KIES 1.5 or 2.0
The USB storage can be accesed,phone memory cant be accesed .
But when i switch off USB debug mode, and select KIES in phone
the USB debug gets activated and KIES doesn't recognize it.
The Samsung USB Android driver fails to install on Windows 7
Phone is fine ,touchscreen is awesome ,PC support is worse than pathetic
