Honestly the xperia Z is awesome and highly durable. I have dropped it soooo many times and not once did it break! The camera is actually very good( both front and back) I’m wondering if the people complaining about it are really using the xperia Z. I upgraded it to lollipop 8 months ago n it works just fine! No dragging! The only draw back is the heating, but it hasn’t affected my phone in any way. I will definitely upgrade to a Z4 or something
