Sony Xperia Z1s Android 5.0.2 Lollipop is live

After factory reset, lag problems are gone. Battery consumption still is a problem, though it is less of a problem than before the reset.
 
So, what's the jury on the Lollipop update? I'm thinking about updating to Lollipop, but I've seen a lot of complaints about it. Is it worth it? Does it make the camera any worse?
 
Does it make the camera any worse?

Sony camera is still not the best I was hoping it would improve magically.
I still can't change lockscreen images to anything other than the default ones which bugs me.

YMMV
