Chosen Solution

Hello everyone, My iPhone 6s Plus has stucked in headphone mode. I did already clean the headphone hole by using a cotton bud and a hair dryer. Moreover, it was already reset all setting. Unfortunately, the problem cannot be solved. I can hear the sound during adjusting the ringtone. I think there is no problem from water because the water indicator in the sim card slot remains white. Are there other ways to solve this problem? Should I change the lightening port and a headphone jack? Thank you very much !!!UPDATED 10/02/2019!!! The phone can show the volume scale when I unplugged the charging port from the motherboard. I heard also the sound from the ear speaker.

!!!UPDATED 15/02/2019!!! I changed the charging port last night. It does not look as nice as the original one, but it works. I spent about 3 and half hours to fix it. Thank you very much for the help.

You should change the charge port assembly and that will solve your headphone mode issue. Most likely you have dirt or mositure in the port and the sensor believes there is headphones stuck inside the port. First thing to try is to unplug the charge port, if it’s not in headphone mode, replace the charge port …. Change it completely and your issue will will be resolved.
