Samsung opposit to Android OS adopt new OS, known as Tizen.
and launch Z1 smartphone into market.
but it was not get much attraction into market, moreover as per my perception samsung launch z1 into market withought any serious intension.
becuase when I was use this phone, this phone is full of bugs, drawbacks, crashes into system.
it locks like that samsung did not test its working before its launching.
this z1 is not a smartphone but a uselessphone.
