Why are some app notifications disappearing from the status bar? For instance, I installed Wifi Status, which is supposed to show up on the status bar when my tablet is not connected to a hotspot. What happens is it appears for less than a second, then disappears (usually its place is taken over by the unmount sdcard symbol) when it should be on. Also, when I tap on the status bar, the long date appears for awhile, then goes off again. Are these normal? Other app notifications, such as Battery Booster and Advanced Task Killer Pro, do stay.
