[Xperia Play Q&A, Help & Troubleshooting] S34Qu4K3:
Confirmed! Icons like wifi icon, battery or signal are handled like a group, separately from clock. Handled by status_bar.xml :D

I think that I found the proper values :)

Left icons was changed also :P It seems that there are in the same group

status_bar.xml

Now we have to find where the "system icons" (data, signal, wifi, etc) are handled :) I think that there are another two groups beacause the space between wifi for example and data :P. One group phone status like wifi an another signal+battery
