Samsung Galaxy Quattro, GT-i8552; pre-July 2014, rooted
I have already modified stock Jelly Bean 4.1.2, rooted, deodexed, debloated 82 system apps, has busybox, init.d support
B) Recently, I have been trying to change background colours of status bar, expanded status bar, notification panel, settings, pop-up panels, horizontal dividers etc. I referred to many XDA topics and threads. I could successfully modify background colours at many places.
But even after modifications / changes in different XMLs, 9.PNGs and PNGs, I could not change background colour as under:
1) background colour of the top area of expanded status bar (where clock and date appear)
2) background colour of brightness controller / bar on expanded status bar
3) background colour of area where "Ongoing" and "Notifications" text appears on expanded status bar
Please see the screenshot with arrows pointing to those areas.
