How to switch back to headphone mode on 4s
Recently, many users have reported that their mobile phones suddenly entered "4s headphone mode", resulting in the failure of external sound to play normally. This issue has been a hot topic in online discussions in the past 10 days, especially among iOS users and some Android users who have encountered similar situations. This article will explain in detail how to solve this problem and provide structured data to help users operate quickly.
What is 4s headphone mode?
"4S headphone mode" usually means that the mobile phone mistakenly recognizes that headphones are plugged in, causing the audio output to be forced to switch to the headphone channel. Even if the headphones are not connected, the external amplifier cannot work properly. This problem may be caused by a system bug, a dirty headphone jack, or a software conflict.

How to switch back to normal mode?
Here are several ways to solve the "4s headphone mode" problem, applicable to most phone models:
Method 1: Restart your phone
The easiest solution is to restart the device. Long press the power button and select "Restart" or "Shut down and then restart". The system may automatically fix the audio output problem.
Method 2: Clean the headphone jack
If there is dust or liquid residue in the headphone jack, it may cause false recognition. Use a cotton swab or blower to gently clean the interface to make sure there is no debris blocking it.
Method 3: Check audio settings
Enter the phone settings, find the "Sound" or "Audio Output" option, and confirm that the output device is "Speaker" and not "Headphones". Some Android models also need to turn off the "headphone mode" switch.
Method 4: Update system or reset settings
If the problem is caused by a system bug, try updating to the latest version. If the problem persists, you can back up your data and reset all settings (not factory reset).
