When I bought this phone it started off well, only problems I had at the beginning was the super-sensitive screen, which is still a problem, if so much as a hair touches the screen it will glitch out and think 100 fingers are tapping the screen at different times, very frustrating. Only recently have I started having problems with this phone, its been about a year and it's become UNUSABLE. The battery lasts about an hour, it takes about 6 hours to charge to full and then only get about an hour of usage before it dies again, especially if your running more than one app. The delay between my finger and the screen is unbelievable, sometimes having to wait 10 seconds+ for a response, unacceptable. My phone no matter how much I clean the storage is so slow.
Rear camera scratches very easily even with protector is worn on. Camera's lens get very scuff so that leads to muddy and unclear pictures after a while. User experience? Terrible. Not even near to genuine Android. Battery life span? Disgustingly shocking!
It's a good phone but don't expect to much, after all, it's a mid-ranger. The camera is fast but sometimes the focus is not accurate, the display has very good colors but is only 720p. The audio is below average in both loudness and quality.
The first ever phones which make me buy a cheap Chinese smart phone! This is the worst phone I have. In all of aspect you can have poor performance! Never buy it.
Also before this phone, I used Xperia Z3, but about 1 year after I used it, without a specific reason , it became broken and useless, that was why I bought this phone.
I think I will never buy Sony smartphone.
