I obviously have a few status bar customizations going on here (Zeppelin, StatusBarCustomClock4, MuteIcon, Bolt) and they all work great -- but can anyone tell me what tweak this yellow square comes from? Sometimes I see it in red. It only just started appearing recently, and I have no idea what tweak it comes from, or what it means. My best guess at this point is that it has something to do with the temperature of the device, because the only pattern I can detect is that it happens when I am out and about and using the device a lot and it feels warm... but that could be a complete coincidence here. I just want to know what this icon comes from, what it means, and how to turn it off. I don't have any tweaks installed that deal with weather, device temperature, or anything else obvious. My Google-Fu has failed me on this one. Anyone?
