This is a very good phone. I have been using this phone from last 3 years. According to performance this phone is very good in all the aspects lookwise this look like xperia z1.we can see phone fully covered with flaps which help phone waterproof and dustproof
It has camera of 20mega pixels. Talking about camera its great even in darkness
Screen it has bravia screen which is pretty good it has better quality
Coming to performance its beast doesnt hang as other phones does even after three years
Sound is not upto to the mark with headphones its ok
Battery for a heavy user is 4-5 hours with internet for a normal users it may last for one day
Bottom line is its good and keep ups it caption best of sony got better
