ZUI 2.0.133 ST

Nov 18, 2016
Hello guys!
When I bought my Z2 I had 2.0.069 ST ROM :) So I wrote to shop where I bought it and said them, that I had a problem with soft. So they asked me to send phone to them and they fixed everything :) And today I get the phone back. I thought that they installed the newest version of software, but now I have 2.0.133 ST ( Android 6.0.1 ZUI 2.0 for everyone by franck 076) and on the phone I found zip file ZUI_Z2plus_2.0.133_GLOBAL_frank. And now my ZUK looks like new phone from google I mean google pixel.

Somebody can tell me more about this soft and it is worth to let it on the phone?
