Sony Xperia Z1 having 2.2 ghr quad core processor, 5 inch Full HD screen with 441 ppi, 2 gb ram, 16 gb internal memory.
Phone comes with 20.5 megapixel camera. Also I got lollipop update now. The phone is looking completely different after update.
Phone doesnt lag in daily usage. Gaming experience is awesome. You can play almost every game on this.
The only corn is display quality. Display is above average.
I suggest if you are game lover and you doesnt care about display quality you go for it.
