although this is a water resistance mobile with 4 Gb ram with snapdragon 820 but it doesnot have usb type c. which is one of the next generation of the usb type lets hope this will come in the next series and i am sure this will not come on the upcoming note 6 too. coz as we all know that note series are almost same with the s series
 lets hope Samsung will puts usb type-c on upcoming mobile phone with giving continue the water resistance feature which is awesome feature, this will make easy for use of phone on rainy day and on taking shower....

if you are the user of Samsung s6 or note 5 or edge then this is note the mobile of you, if you think you need to update your mobile then you r totally wrong, almost all feature of the s7 is on s6  so i think you dont need any upgrade this time
