My iPhone is almost always stuck in headphone mode
My iPhone 3G thinks it has headphones plugged in most of the time. If not, if often switches over within seconds of running an app or talking on the phone. When it does switch, it will even disconnect from bluetooth devices. It's been doing this for months and I'm tired of being afraid to answer the phone for fear they will hear silence. I can switch on the speakerphone to hold a conversation but that is hardly practical.
I've seen many others with this problem, but I have tried those solutions many times to no avail. Things I have tried include:
-Blowing or sucking air through the headphone jack and dock port.
-Cleaning the headphone jack with a Q-tip and alcohol
-Plugging and unplugging headphones several times
-Doing a full software restore of the iPhone
If you have this problem, try the above solutions first. Perhaps we can find more clues to what is causing this.
When it first started, it seemed to kick in after several minutes of heavy use when the phone would get hot. That seemed releated, but now it is basically all the time.
Esta é uma boa pergunta?
