Well this mod is made to remove that.
So lets get to the guide straight away.
This has been made on my device running XXBMD4 i have not tested this on any other version so install on your own risk.
This is based on the STOCK XXBDM4
I am not responsible if anything happens to your device after installing this.
This is similar to what has been implemented in cosmic ROM but i have not stolen it from there.
Go to http://d-h.st/WWx and download the SystemUI.apk
Transfer the file to your S duos.
Using and file manger (i prefer root browser) move the file to /system
Edit the permissions to rw-r--r-- (as shown below)
After the permissions have been changed move the file to /system/app
Enjoy and hit thanks if i helped you
Special thanks to
@abhi922 (for helping me with apkmultitool)
PS in the photos i am using an xposed mod called tinted status bar. But this mod works even without the module.
