Yep, but 0 bars is actually used to indicate that you DO have a signal under normal circumstances, which is why is so confusing. When the phone is working normally, in my house the signal switches between 'No signal', 0 bars and 1 bar. Both of the latter icons indicate that I have signal. It was only when this problem occurred, that the cellular network was not functioning at all. It was not that I had no signal, but that the modem or something wasn't functioning at all and it displayed the 0 bar icon rather than something representing an error. Edit: Just retested it to see if this had changed recently. The 'No signal' has been swapped for the 0 bars icon as you've suggested, but it's also still used for a weak signal too. So, there is actually no way to distinguish between low signal and no signal. The call button and send sms button disable when there is no signal, so I just observed that as I went out of signal, and the buttons became disabled, there was no change to the network indicator. > (Various people have suggested I shorten other cellular error cases, > "SIM error" and "No service", to just icons too. I've maintained that > an icon alone wouldn't be obvious enough.) I think an icon only is fine, especially if you highlight it by giving it a red colour. Additional details about the error can easily be displayed when the indicator is pulled down.
