Q: My iPhone has stuck up in headphones mode

This article might help to troubleshoot speaker problems on the iPhone:

If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker - Apple Support

This worked for me thanks to r850723
1) have someone call you, 2) turn on to speaker mode, 3)turn off the speaker, 4) plug in your headphone, 5) un-plug headphone. This should work!

I had the same problem and contacted Apple Support via Chat. A helpful guy took me through a process to force a software download via iTunes. It cleared a dodgy bug in my software and fixed the problem.

This absolutely fixed my problem after following all the other advice and nothing worked!!! Thank you

Hi,

I too faced same issue recently and somehow able to resolve it. Please try below steps : -

1) Clean your headphone jack(small round hole beside of charger point) with earbud. Insert earbud and try to revolve in circular direction 8-10 time. Hopefully it will work. If not follow 2 step.

2)Take one needle and try to clean connector(golden ball) inside headphone jack(This works for me)

Basically this happens due to dust or carbon or when headphone jack connector(golden ball) stucks.

Hope my answer will help you to resolve your issue.

Thanks
