Samsung is one of the best smartphone creator company. But samsung z series is the one of thr worst series ever. main reason I hate it because of its new operating system. Which is complicated and not support or not able to access full android apps.
Tizen operating system has its own store but it does not has all the nessary apps. Tizen doesent support high level graphics that means you are not able to play high level games like Nova.
I suggest you to don’t buy such studpic smartphone with stupid Operating system.
