sony z ultra 5.0 update issues

[nter]

I updated my z ultra to the 5.0 lolipop version,but it is very very buggy.
1.The wifi is turning on and off from 2 to 2 mins IT IS VERY ANNOYING **bleep**
2.The camera is very laggy comparing to 4.4
3.When you have x-reality on and a live walpaper from sony on the lock screen,when you wake up the phone the background of the lockscreen is creepy,the quality is very poor utill i unlock it,and x reality is keeping modifing the colors,it is very strange.
I want to know what can i do in this case...

Hello all, seems the issues do not have resolve...

   I am having all those existing issues of the posts,

 I have a sony xperia 3 i gave to my GF, as i upgraded.. so i do love the phone, especially the equilizer i can tweak my audio,

but after the update, clear audio and equilizer are nulled from the update,,,

 SO i urged my GF to not update and works fantastic, whilst my ultra z is dud on several aspects of why i like the phone...

 please fix this with an update, sony people, you empire of smart people can shed some light on a kind update.

 thank~
