Galaxy S2 thinks headphones are plugged in

Hmm interesting I would check your sound settings and try rebooting your phone, other than that, I have never heard of that.......

 

have you tried plugging them in and unplugging them again? I haven't ran across that issue. A reboot might be in order too.

I use Bluetooth ones

 

Download the app Sound About from the Play Store. Seriously.

 

Moved to the rooted section.....

 

Spray some rubbing alcohol in the port....use qtip to swab out any pocket lint....

that's why its best to get a case that has port covers like the Krakken case by Trident Cases

 

I would not advise doing that with the phone on.


Many rubbing alcohols are only 50% and most top out at 91% the rest is water. For dust, an air dusting spray can works well.

If you don't use your headset port often, a simple fix to keep it clean is to cover it with a piece of Scotch Magic tape.

 

I too like the cases that cover your exposed ports. My otter box does this well.
