Stuck on Headphone Mode

If your iPhone is still stuck on headphones mode after turning off - after making sure that headphones aren’t plugged into your iPhone and/or tried a hard reset, putting your headphones in, and taking them out again- there’s a great chance that there’s a hardware problem with your iPhone. 

At this point, this problem is being caused by one of two possibilities:

📱 The headphone jack is damaged, either physically or with liquid.
A very common reason for iPhones getting stuck in headphones mode is water damage. The headphone jack is one of the only openings on the outside of the iPhone, and that makes it particularly susceptible to water damage. 
Another very common reason why iPhones get stuck on headphone mode: The headphone jack gets pulled away from the logic board.

📱 Debris stuck inside the headphone jack is fooling your iPhone into thinking that headphones are plugged in.
Poking around in your iPhones headphone jack can damage it, but most people agreed it was worth the risk because they really had nothing to lose. Since repairing your iPhone to iCenter or apple stores can be very expensive and to make matters worse, debris stuck inside your iPhone’s headphone jack isn’t covered under warranty, better yet think what will be your next move after knowing you have this situation.
