First thing that you want to try before assuming it's a hardware problem is to hard reset your phone. You can do this by holding the Power and Home button for 10-15 seconds, or until the screen goes black and the Apple logo shows up again.
Second, try to plug in a pair of headphones into the headphone jack and remove it after. Sometimes, the headphone jack may appear to be ""stuck"" because it still thinks there are headphones in the phone.
If these troubleshooting tips did not work, then I am afraid it may be a broken headphone jack. Unfortunately, since the headphone jack is tied to the lightning cable flex cable, you have to replace the whole flex cable. iFixit has the part available on their website if you look up the product code IF124-010-1 in the search bar, but I recommend eBay/Amazon because it is significantly less expensive."
The speaker in the iPhone was fine. I had to replace the lightening cable, microphone flex cable. I did test the replacement speaker, but the sound was really distorted. So I kept the original apple phone.
I would recommend getting a genuine apple part, but thats difficult to source. Even the parts on this website aren't genuine parts.
"I recently change iPhone 5s battery after watching video on YouTube for 3 days.
It went well and after fixing the new battery and closing the screen i found the phone sound lost.
I opened the screen to look inside and found the touch ID protector was no fully inserted. So i reinsert until hearing a click sound. Found out it was the main culprit for the no sound .
Putting back the screen do testing and use the phone awhile and getting no sound again. So once again have to take off tge screen and secured the plat in place. Then i realize there was a little dust on next to the home button and wipe it off. Test the sound and it was working again. Shut the screen on. And been using my 5s for 2 days with out complain."
I replaced my iPhone 6 Plus battery. Everything is working perfectly. I noticed this morning my phone is now stuck in headphone mode. It still rings when receiving a phone call and it auto puts on speaker and I can still talk on speaker. I just have no sound and no text sound notification. Should I replace the whole lightening cable and head jack part? Or is there something I may have hit that caused it? Please help!
