Well I was very excited when sony announced this handset as it was going ti be the 1st p g one with the 4k display but do we really need it.can we see the difference comparing it to be 2k displays when I saw it personally for me the answer was no.
It does show a bit of sharpness in the gallery if u have very good quality images otherwise the phone runs in 1080p all t b e time apart from gallery & media playback.there are not much of 4k content as well as of now but quodous to sony for experimenting the same also the dual front facing speaker could have been more loud. Expecting a better product.Sony.
