One of my friend recently buy Sony Xperia XZs as Sony is one of trusted brand in mobiles. But when he uses it about 3 to 4 months he identifies that it has many lack of specifcation.
First of all the phone starts heating if you use it for only 30 min or if you continue to use it hangs and all you see is a black screen for sometime.
Its sound is not so good and its menu is quite hard to understand for a normal person.
Its style or looks are not so good as compared to other phones of this range it looks like a old phone if you place this phone among other phones of this range.
Its features are average as per his price. So at the last thick twice if you are going to buy this phone and according to me you should consider other options than it.
