I have this strange icon that appears in my notification bar (on the right hand side) every once in a while. I have only seen it when running an app in fullscreen, and then checking stuff in the notification bar. It disappears after a few seconds when quitting the full screen app.

    Have you looked at all your installed apps to see if any of them have a similar or related looking icon? Jan 7, 2015 at 12:30

    @MichaelKohne Worth noting: "in my notification bar (on the right hand side)" (emphasis mine). That almost rules out an app, as the "right hand side" usually is reserved for "system status".

  • Checking my sources, this might be a status icon signaling "Location service is ON" (see network icons on this page, right column, third-to-last row). Unfortunately, each manufacturer seems to use his own set of icons, so it's hard to say. So you might try a Google Image Search on the terms "htc notification icons" (a good load of useful results, I've just tried).
