I am using Sony Xperia Z4. There is 3Gb ram in Sony Xperia Z4. It’s camera is 8.1 Mega pixel but this is not Gsm device, it will not work on any Gsm network world wide. It’s internal memory is 32 Gb.It has 1.5 Ghz Quad core processor. This mobile memory supported up to 128 Gb.Its secondary camera is 5.1 mega pixel. This mobile is very amazing according to me.
I am very happy by using this tablet and I am not facing any problem in it. It is reliable and smooth to run. Its style and design makes it more beautiful and its feature are amazing.
