The new paint job makes its debut in Taiwan and, unfortunately, thats the only location where it is available. It will land at Samsung stores and Chunghwa Telecom in the beginning of December at a price of NTD 30,900 for the 128GB model.
Buying a white Galaxy Note9 before December 31 will net you a free Fast Wireless charger (normally worth NTD 1,190).
Anyway, this is the fifth color option for the Galaxy Note9 and one it doesnt share with the Galaxy S9. Still no gradient colors, though.
