I ran into a problem last night with the status bar that has continued into today. I was listening to Pandora last night and it stopped randomly so I checked my phone and noticed that both Apex and Nova launchers had updated automatically. At the same time I lost my status bar completely. I did a reboot and a full power down and it never came back. I had TouchWiz set as my default launcher so I cleared that thinking the updates may have caused an issue. Still no luck. So I cleared cache and reinstalled 4.3 and the status bar came back but it continues to disappear randomly and when it does I can't get it back. Anyone experiencing the same issue? Any thoughts?
Sounds like something went wonky with the systemui.apk. Have you tried uninstalling the updates to apex and nova launcher?
