phone app theme

[ZeeRush]

HI 

I did an update to lolipop for my Xperia z1 phone

After the update the phone app theme was changed and I was haooy about the new theme

Now I did a factory reset to the phone, and the android version remains lolipop 

However the phine app theme got back to the older version as it was on kit kat

Any ideas how should get the new theme back? 

Thanks in advance

That's rather odd, it should affect the app, you could reinstall the update. 

You could also, side load the app, check the XDA Forum.
