Well I am using xperia z1 from 1 year and I found it very great and its because I am a biggest fan of Sony Brand. in this phone you will find almost every feature that everyone wants. sony xperia Z1 is the first phone in Z series this was the great accomplishment of Sony it has a big display with the amazing graphics quality and sony is a top brand for amazing displays because it has a bravia engine that makes it very real.
I have been using this from long time and I didn’t find any problem not even a single lag and the camera is really impressive you can click pictures with a great quality thats what people want. the performance of this phone is also good it works fast even faster sometimes. and the other thing I like about sony is the sound quality wow it has a perfect dolby sound what I am telling you here is you can listen to every beat in the music thats really ground breaking.
The design and style is very good I like this phone I suggest everyone to go for this because it has a awesome battery backup.
