It may be that the micro-switch of the earphone hole is invalid, or that the earphone hole is wet with water, or there is a foreign body that causes the earphone mode.
Try the following methods:
1. Restart the phone or quickly plug and unplug the headset several times until the headset mode is released.
2. Use a cotton swab dipped in alcohol to rotate and wipe the earphone plug and mobile phone jack (the plug or jack may be oxidized).
3. Connect the headset to the interface, turn on the ipod to listen to music, then press Pause, press home button to return, turn off the iphone (without using other third-party software), pull out the headset, and then turn it on.
4. If you don't try several times successfully and it still doesn't work, press and hold power home for hard restart. Then, when a white apple appears, unplug the earphone to release the earphone mode.
The iPhone only vibrates, but what should I do if there is no sound?
The settings on the iPhone are as follows:
Settings-Sound
The contents in the sound settings are as follows:
Ringing mode vibration
Silent mode vibration
Ringing and reminding sound are also the loudest.
But the phone still doesn't ring.
After many attempts, it turns out that here, you just need to adjust the "mute button", and then try calling someone else's phone.
What should I do if the speaker of Apple's mobile phone has no sound and the earphone is plugged in?
Apple's 4s,16G, speakers have no sound, and listening to music, watching videos and playing games have no sound. But there is a sound after plugging in headphones. There is a sound when the mobile phone answers the phone, so it can vibrate when the message comes. And sometimes it's good and sometimes it's not good. When it's not good, it doesn't respond by adjusting the volume on the side of the phone, that is, under normal circumstances. Expand
First, determine your hardware problem. If your mobile phone has not been dropped or flooded, it is probably a software problem. Especially if you escape from prison, you may have installed some "dirty" software, which will cause the receiver to fail or the speaker to fail because it is not properly tested or has bugs that conflict with the system, which is very common in Android system.
How to fix it:
First, you can try to delete the extra software on your mobile phone. General problems can be solved. Of course, delete the postscript and restart the phone. If it still doesn't work, try to refresh the system. Under normal circumstances, software problems can be solved. Judging from your problem, it should be a software problem.
