iPhone screen shuts off when in voicemail
I have noticed that when I am on a phone call and the screen is supposed to go blank, it fades discretely to a blank screen then comes back when I take the phone off my ear. When the screen goes blank on the voicemail screen it shuts off like someone is pulling the plug on it - its very weird.
My first 3G iPhone had a similiar problem with all calls I dialed or received. That phone was exchanged for a new one eventually as the Fido rep could not fix the issue.
Anyone have any ideas?
I have restored the phone, got the latest software, reset it etc...
