How to fix sound issues on your iPhone 4 or iPhone 4S

Having sound issues on your iPhone 4 or iPhone 4S? Here's how to fix them.

If you’ve got an iPhone 4 or iPhone 4S that’s having some issues with sound, you probably aren’t alone. Issues could range from system sounds working but your iPhone not actually ringing or system sounds not working unless plugged into the headphone jack. While sound can be caused by several issues, symptoms like this are typically fixable with a pretty simple DIY repair.

If any of the above symptoms sound like what you’re experiencing, follow along for a more detailed list of symptoms and how to correct the problem.

This week we’re doing things a little differently and instead of giving you a newrepair, we’re going to take a look at some existing mods that should fix very common sound issues pertaining to both the iPhone 4S and iPhone 4.

Disclaimer: As with any repair, neither iMore nor The Pod Drop can be held responsible for any damage you may do to your device. It’s also worth considering that opening up your device to perform any repair or modification can and will void your Apple warranty. If you don’t feel comfortable opening your device, don’t. Use extreme care and caution when performing a repair on any device.

Not comfortable with DIY repair? Leave it to the pros

If you aren’t comfortable performing a DIY repair on your own, don’t. It is possible to cause more damage or run into issues you aren’t ready for. In this case, it’s probably better to either pay the money for a replacement device from Apple or use a local or mail-in service that will handle the repair and any issues that may arise for you.

The Pod Drop has many locations in the midwest and is a rapidly growing company. You can check for a Pod Drop location near you, mail it in, or use another third party repair service. For more information on mail-in repairs or possible Pod Drop locations near you, you can visit their website.

If you are comfortable with repairing your own device, put your ninja pants on and keep reading!


Sounds issues are a common problem we see with the iPhone 4 and iPhone 4S. Some users have been experiencing quite a few simliar issues lately that can be solved quite easily using repair guides we already have readily available to you. If you’re experiencing any of the following symptom combinations, we would suggest trying the repair solutions linked below.

No system sounds

Your iPhone 4 or iPhone 4S will ring when someone calls it or you can go into Settings and get sounds to play but system sounds don’t work throughout iOS such as keyboard clicks, lock/unlock sounds, and certain system notifications.

No alert sounds

If you can go into Settings and hear system sound previews but no sound actually produces when an alert such as a phone call, text message, or email come in.

Combination of no alert and/or system sounds

If your sounds work sporadically or in any combination of the above symptoms.

How to fix sound issues

Try a DFU restore first

Before performing any kind of hardware repair, you should always try a restore first to rule out software issues. A DFU restore is the kind of restore we recommend for issues like this.

Replace the dock connector

Wait, what? You may be asking yourself why replacing the dock connector would fix sound issues. Actually, the dock connector component contains some wiring and components that delegate sound throughout your iPhone. In our experience, if you’re experiencing the sound issues like we’ve described above, 9 times out of 10 a dock connector replacement fixes the issue.

Depending on whether you have an iPhone 4 or iPhone 4S, you can check out our guides and replace the dock connector on the device on your own. It’ll cost you a lot less than a brand new iPhone and will only take about 30 minutes. The best part is, you should have sound again.

Other sound issues

If you’re experiencing no sound at all or it is heavily distorted, your issue may be the actual loud speaker itself or another component related to how sound is handled. We have many tutorials and guides for replacing other components related to sound in our DIY section that you can access via the links below.
