i have an htc sensation xe (rooted) with ics 4.03 installed. the notification icon disappeared over night as well. i had to uncheck and re-check the “show notification icon” to put it back on.
We are looking at it, but thanks for the report. I’m actually glad it happens on rooted devices as well

Hi everyone,
I think I found the issue with the disappearing notification icon. It’s a bug in ICS, not in AMS 
We’ll try to fix it so hopefully the icon won’t cause any troubles anymore. Also note that even when the icon disappears on ICS, the application using the icon is still running the same way as it is with the icon displayed, so no functionality broken or denied in that case.
Filip
That’s good news, as it has just started happening again on my Nexus 4.0.2. But not on a regular basis, just occasionally after coming out of a period of inactivity.
Filip, mine disappears also. But I confirm that the application was running in background.
Yes, that’s my experience as well

Hi folks
Is any chance to make notification icon a little bit smaller ? Currently on my HTC Sensation it looks like this:

Similar size to the icon of 3G WatchDog would look better IMHO
There are some plans about adjusting the icon, might take some time to put them in motion though, so no promises when that will be.
Filip
I don’t have setting option to remove the icon notification bar.
Possibly because you have tagged along on a topic that is over 5 years old.
Lots have changed, not only in the avast mobile security, but also the Android OS version, not to mention Google changing the rules in relation to notification icons.
