I got this silly bug on my iPhone, the overlay bell (the one that should appear onscreen when you turn the ringer switch on) appears without me touching anything. This does not happen when the ringer switch is off (i.e. no slashed bell spontaneous flashing).
I have reset the iPhone a number of times without success and I really do not want to restore the firmware just for this, but it bugs me a lot.
Any help will be appreciated. Thanks.
