I want to share something about my experience with sony xperia Z2.
It is the worst mobile I have seen in my life.One of my friend purchased sony xperia z2 brand new because I suggest him to buy sony brand mobile cz it is called "water proof mobile". One day his mobile fell into the water and after that display of mobile is not working but the most imported thing that concern person of sony service centre is asking we can not do any thing. We cant help you for the same.
They are not replacing his mobile. So friends my suggestion to you please never purchase sony mobile in your life .I dont want you to suffer like my friend.Now the choice is yours.
