Recently my z1c's status bar starts rolling up and down itself. (you see me now, you see me not)
Although there is no issue with scrolling down the bar.
Still, it's annoying seeing it goes up and down non-stop.
Does anyone has solution for this?
I've reboot to safe mode.
It doesn't happens there.
Totally normal.
What should I do next?
This means that there's an app you've installed causing this, you can go uninstall apps one by one until you get rid of this problem, or you can wipe/reset your phone and start fresh. Your choice.
Aww man... gonna take a lot of time.. 
Anyhow, thanks a lot Quester!
No problem. If you decide to wipe, I'd suggest that you do a PC Companion phone repair, this will do a clean installation of the latest firmware and will also wipe your internal memory. You'll have to back up your data before you proceed, SD card content will not be affected.
Open PC companion -> Support zone -> Phone/tablet software update -> Repair my phone/tablet (blue link style). Follow the steps given, do not connect your phone until prompted to press volume down while plugging USB cable.
Hey, now only I see your message.
