Samsung Z2 is a smart phone which support 4G networks and comes around 5, 000 but it does not work like a android means here installation is blocked due to which you cannot install any app in this phone and you can only install those apps which are available in their tizen store which are not enough in this type of generation and here whatsapp is also not updated which create a very big problems for those peoples which are connected socially so I think people have to look out on other phones .
