Click on any of the guides below in order to be taken to a description of that guide explaining common symptoms, diagnostics pertaining to each repair, and a link to each full guide. Now that the iPhone 4S is more than a year old, many users may want to change their battery if their charge cycles aren't what they used to be. This one doesn't need any introduction and is one of the most common DIY repairs for any clumsy iPhone user. If this sounds like a problem you're experience, we've got you covered from start to finish. A DIY repair can remedy the issue but be aware this is a ninja level repair as the components and cable you have to replace are very small.
The dock connector assembly in the iPhone 4S controls quite a few key components in your phone. While most sound in the iPhone 4S may be dictated by the loud speaker assembly or earpiece, they're not the only components that have to do with sound. The iPhone 4S is known to have sound issues where system sounds seem to work when you preview them but they don't actually ring or system sounds altogether don't work but music will play. If you're experiencing issues with cellular reception on your iPhone 4S, the cellular antenna could be defective. The vibrator assembly is a super essential function and necessary if you want to be notified you have a call or a message coming in when you can't have sound activated.
While the rear facing camera is great for capturing the memories around you, the front facing camera is a great way to communicate with relatives via FaceTime and capture self portraits.
Symptoms of a bad front facing camera typically amount to the shutter never opening no matter how many times you restore the phone or reboot it. Luckily, an earpiece replacement is on the cheap side and isn't terribly hard to perform on your own.

If you've dropped your iPhone 4S, you may have noticed that the steel frame around edges can become quite sharp.
Replacing them will require some patience but we're pretty sure your fingers will thank you. If a combination of sounds work through the loud speaker, we'd suggest looking at our other guides concerning sound instead of assuming it's the loud speaker.
If you've run into issues performing a repair on your own or have questions in general, our mod and DIY forums are a great place to start. If your iPhone 4S headphone jack or mute switch is giving you issues, a DIY repair on the cable that handles those functions can remedy the problem.
Regardless whether you're having headphone jack or mute switch issues on your iPhone 4S, this guide can walk you through how to get both functions back in working order again.

To replace the headphone jack and mute switch cable, follow the removal instructions exactly in reverse. To reassemble your iPhone 4S, you can either follow all these directions in exact reverse order or view our reassembly video guide above which will walk you through how to reassemble it from screen to turning it back on and testing it.
Once you've gotten your iPhone 4S completely reassembled and you're positive you don't have any leftover screws, you can go ahead and turn the device back on. If you've run into issues or things aren't going the way you thought, our DIY and mod forums are a great place to start. And if you're not, follow along anyways and we'll refer you to the professionals that can do the repair for you.

Use the area that the rear-facing camera was located and the bottom of the logic board to lift it straight out. This is the tricky part so make sure you're very careful while performing the following steps as the cables are very delicate. Do not attempt to completely remove it yet as it's still attached.You may choose to remove the actual power button if you'd like but it's not necessary. Again, don't completely attempt to pull up the cable as it is still attached to the midframe of your iPhone.There is a black bracket located directly above where the earpiece sat.
Don't screw the bracket screws in too tight or you'll have issues with the button not depressing.
Tap the power button several times to turn the screen on and off just to re-confirm everything is back in working order.

If any of these issues sound like something you're experiencing, make sure you check out our guide to see if it's the right one. It makes everything from photographing first steps to family events to sending videos straight to YouTube super simple and crystal clear.
If you frequently use your front facing camera and it has decided to stop working on you, we can get it up and running again. In rare instances you can also see lots of distortion or lines through the screen only when the front facing camera is open. If you aren't ready to upgrade just yet, a DIY repair for an earpiece is a realistic option for many users. If one of the volume buttons has become ridged or jagged, it could potentially be a safety issue. Music, ringtones, and text tones will most likely not play unless you have headphones plugged in. In our experience it's normally the dock connector or earpiece that are the culprit but that doesn't mean the loud speaker never decides to be unruly. If you still can't find answers to your questions, you can also email us and we'll try and answer whatever questions you may have.

Symptoms typically include audio cutting in and out when headphones are plugged in or no sound at all. It will show a complete breakdown of the device but smaller steps for each individual repair will be listed with high quality images in the actual guide below.

For a headphone jack and sensor cable replacement, you'll need to watch from around 5 minutes and 3 seconds to the end of the video. Over time, the cable wears down and causes the actual power button to become harder and harder to press. One of the cables lies underneath the bottom most cable so you'll need to disconnect the cable over it before folding it back and revealing the shorter cable underneath. Gently lift the shield out of the iPhone and set it aside.Take your spudger tool and gently pry up the dock connector cable and peel it back as shown below. You'll only need to watch from the point of replacing the logic board after you've got the front facing camera secured again.
Even after you decide to upgrade your iPhone, your old one always makes a great hand me down for a child or relative that doesn't always need the latest model. If your iPhone 4S won't register a charge or doesn't show up when plugged into your computer, the dock connector could very likely be the culprit.
If everything else on your iPhone is working perfectly, a replacement antenna will cost you a lot less than a brand new phone.
If you have absolutely no sounds through the loud speaker portion of your iPhone 4S but everything works completely normal through headphones, then odds are your loud speaker assembly has in fact went out.
The mute switch can also face issues where turning vibrate on or off results in no response or the switch itself being loose.
Take care to pay attention as to how it was laid so you know how to put it back during reassembly.Use your tweezers or a pry tool to carefully loosen the noise canceling mic from the upper frame.
