Acer Iconia A200, Acer ring doesn't show

Hi everyone!

I'm having a problem regarding my acer ring on the device acer iconia a200 tab. The ring button doesn't show at all. Its enabled in the settings, I tried restart, uninstall and re install the update, switching off the app killer. But the ring is not there. I would show the screenshot but it also works through the ring. Any help would be appreciated.

Just for the safe side, i should tell that i disabled following apps, is there any of them linked with the ring (Ring is enabled):
Astro
Aupeo
Browser
Clear.fi
Docs to go
Facebook web
Google play books
Google play magazines
Google play movies
Google text to speech engine
Google+
Life digital clock
Media server
Movie studio
Social Jogger
Sound Hound
Talk back
Voice search
XT9 Text input
Zinio

--Update--
I just enabled the weather and clock and its back again. Looks like they are connected somehow. Please close the thread.
