Hi all, Chris here from Australia, First post. Just wondering if anyone else has the same issues I have been having with my Iphone 4 16gig running 4.3. When I answer calls and put it on loud speaker, and then change it back to normal spaker after a while, Some times it will go straight back to loudspeaker, or mute the phone call, Its like the sensor doesn't sense that its against my ear. Now this is the fourth phone I have had exchanged, not all for this issue, but the last two have done it to me, including a brand new one direct from apple headoffice in australia. They claim that there was a software update some time ago to fix this issue and don't see why it would still be doing it. I just not sure if im going insane and picking on a silly issue with the phone lol So any help will be much appreciated.
