Lenovi zuk z1 which releases september 2015 has 5.5 inch hd screen with 13 mp rear camera and 8 mp front facing camera powered with 4GB of ram and snapdragon 801 chipset the pros and cons I noticed using it for 2 weeks are:
Pros:
The audio output via headohone is really really good
The cellular call quality doesnt have any issue regarding network or data
The finger print scanner also doesnt have any issue works fast and is reliable
The rear view camera is best in thia price range best colour accuracy
The front facing camera also works really good but audio pick up is low
Battery lasts for about 6.5 hours screen on time on wifi or cellular data
55GB of internal memory
Cons:
Auto brightness sensor ia too slow
Defaults apps look ugly and and are slow
Default camera app is also limited

Some timea heat a lot while using camera
