What is

android:paddingLeft="6.0dip"

?

It shouldn't be here :)

I looked inside stock, vanir and other status_bar.xml posted in this forum by other members, but there isn't this padding starting from left side of the status bar to center like the clock

I think it could be the problem :)

It should looks like this:
