I Phone No Sound Problem/ Issues Steps and Solutions

http://iphonenosound.com/

If you have no sound on your iPhone 3 / 3GS / 4 / 4S / 5 / 5S / 5C/ iPhone 6 and 6 Plus volume bar it is unbelievably frustrating as you most probably already know. I have been looking for cures over the web there are many out there, below you will find a list of all these including the one that worked for me. Also the list is in chronological order of what seems to be most successful. It is a process of elimination but it has to be done.

The symptoms of iPhone no sound Problem/ Issues include:
– iPhone will ring but speaker will not work for anything else.
– iPhone no sound at all for calls, apps, music etc
– iPhone no sound as stuck in headphone mode
Follow these steps and hopefully your iPhone will be back to its prior glory.

iPhone No Sound Step 1,

Loud/ Silent switch on exterior of iPhone is switched to silent mode which is orange. If so flick the other way to loud mode. This is a step that so many people miss, but it is the most simplest.

iPhone No Sound Step 2,

Restart the iPhone. Hold the power switch and home button together for 10 seconds. This will restart your iPhone, you wil not lose any media, contacts, data, etc. If there is a temporary glitch on the iPhone this will eliminate that glitch. Also if there is a glitch this may help terminate a temporary glitch

iPhone No Sound Step 3,

Reset iPhone. Go to settings> general> reset> reset all settings. Make sure to backup your iPhone to the cloud / iTunes as this will wipe your media, music and apps although photos will be left on the iPhone. This is a follow on to step 2 and another way you will be able to eliminate the glitch on the iPhone.

iPhone No Sound Step 4,

This one is a bit weird but it worked for me for a while and has worked successfully for other people. Squeeze the bottom right hand corner of the phone above where the speaker is. The left Side is a mic not a speaker so don’t worry about that side. Hold that grip for about 20 seconds. This is done as the connector may be loose and had to be repositioned correctly. Yes strange but most of these solutions are.

iPhone No Sound Step 5,

Use a tooth brush to clean the docking area where you charge your iPhone. With dirt, dust, grime and so on it may block the connectors working correctly and makes the phone think it is on a music dock. When you do this do it gently and get the bristles into there good. Also if you use rubbing alcohol, acetone or methylated spirits it will help get all the extra dirt out. As these products evaporate it will not do damage to the connectors. Do not use mineral terps when cleaning as it is oil based and will not dry!! This seems to be one of the most successful solutions.

 

iPhone No Sound Step 6,

Get your headphones and insert them into the headphone jack and then quickly pull them out. Continue this for a couple of minutes as sometimes it gets stuck in headphone mode so this normally undoes that. Also this may remove any dust or grime that may have been lodged in there.

iPhone No Sound Step 7,

Restore your iPhone on iTunes. Click on your iPhone icon when plugged into iTunes and go to restore. If you do this make sure your iPhone is backed up as YOU will loose all data, media, contacts, pics, and so on. This puts your iPhone back to factory settings. This is similar to step 3 as it is a full reset of the device, this should help eliminate any glitch that have have come out in a recent update such as iOS7 or iOS8. Also when doing this step check for updates.

iPhone No Sound Step 8,

Jailbreak your iPhone to find the file directories that are causing the fault. By doing this you are deleting the file that is making the iPhone think it is on a dock. You will still be able to use music docking station etc. If you have a jail broken iPhone or willing to do it then this will be the best option for you. Very simple video and easy to follow, to jailbreak follow my simple tutoria
