I’ve had this phone for over a year and I must say it has not had any issues till date.
When I bought it I was told that it cracks or breaks easily but I must say(not so proudly) that I have dropped it more than once but its has had not a single crack yet(fingers crossed).
My only problem is that Sony seems to be the only brand for which fun accessories are not available anywhere.
I’ve seen only very basic stuff.
If anyone knows of a website that has fun, quirky phone covers for Xperia Z do let me know
