H icon is flashing, but phone isn't connected to wifi or mobile network

[AC Question]

I just noticed that the H icon is active, as if it's downloading, but my wifi and mobile network connections are both switched off. Anyone know how this can happen, or why? Thanks

Are you receiving a MMS picture? It could be that.. Or just the animation is stuck. You could try a reboot as well.
