guys be careful, don't buy a phone from China, i had one , it is a nightmare, because overtime you like to dial a number the phone hooks up with China Yellow pages and give you suggestions and and and , i now bought one on my way back ( quick stop in Dubai ) in the mall, perfect , because the 4RAM and 64GByte is not available in Switzerland or Germany ....yes the China version has been with 128GByte but , you can't have everything in life .
and the fact that you place a 200GByte SD Card in the phone makes is perfect.
