Iphone 4s power button DIY repair

Apple periodically releases new versions of the iPhone. But users, due to habits or simply lack of time, use smartphones for a long time. It is natural for a person to get used to some kind of everyday things, and it is not convenient to part with an established rhythm. This happens with fairly durable iPhones.

Despite this durability, problems still happen. Various kinds of mechanical breakdowns are simply knocked out of the adjusted operating mode. One of these problems is broken buttons or one button.

Let's take a look at troubleshooting with a specific example - this is an independent repair of the iPhone 4s power button. Let's start by trying to figure out the cause of the breakdown. The problem in question with the Power button occurs for various reasons. This, and the factory defect of the iPhone 4s components, mechanical damage, shock, wear after the expiration of the operating time of the device. Frequent appeal of users to the service center on this issue, due to the design features of the power key and the fragility of the mechanism of conjugated elements. These are spring contacts and a loop that make our power button work. The fact is that in the set of the device, namely the elements that activate it, there is a black plastic part resembling a tubercle. This element is fragile and will break if dropped or otherwise not subject to mechanical impact on the device. In this case, the fragile element of the iPhone button breaks off or crumbles. Of course, in its absence, the button will no longer function.

Before you get started with iPhone 4s, consider whether you can follow the iPhone repair guidelines carefully and accurately. When repairing this key yourself, you need to know that the cause of the breakdown is a small black plastic element resembling a tubercle. If it is missing, it must be returned to its place, securing with glue. It is located on the train. In order to keep the part original for the device and, if the cable itself is not damaged, you can replace it with similar Chinese components. You can carefully dismantle a fragile element from a cheap version of a loop to your own one. But, if there is a malfunction on the loop, you will have to change it entirely. To do this, you can use Chinese components for the iPhone, in online stores, for example: AliExpress. Or solve the problem using the services of specialists, contacting the service center. But there is another option for troubleshooting this kind.

Apple developers, as if anticipating the problems associated with the fragile Power button, added Assistive Touch to Settings. After activating this function, a sensitive key will appear on the iPhone screen, which will be a temporary solution to the problem in question. This key is also a lock button at the time of its operation. To activate this function, go to "Settings", then the item "General" and "Universal access". And there the Assistive Touch function will be available for activation. But unfortunately, this option is acceptable only for a while, until Power can be repaired using one of the described methods.

While there are many ways to solve the power button problem on their own, users should remember that it is always risky. The Internet provides a lot of useful advice on this matter, but does not give any guarantees in the future health of the smartphone. Only in the service center you will be provided with a high-quality repair of the device and will be able to replace the button without damaging the gadget.

If the lock button on your smartphone has ceased to function, further operation of the device becomes very problematic. Is it possible for the owner to cope with such a malfunction on his own, and if so, how? You will find the answers to these questions in this article, here we will look at fixing the lock button on the example of the IPhone 4.

In fact, this process will be quite complicated, at least for people who have never encountered such work. Therefore, if you are not confident in your abilities, ask for help from the masters of the LG service center. Of course, if the problems with the button have arisen due to system malfunctions, then the issue can be resolved by resetting the settings. On our blog, in the article "IPhone how to clear the cache", you will learn how to reset the device to factory settings. If this did not solve the problem, in our service center you can count on prompt repair of the lock button on the IPhone 4.

There is also a solution that will fix the button problem, at least temporarily. The iPhone is initially equipped with a very convenient function called AssistiveTouch and allows you to lock the device from the home screen. If we describe AssistiveTouch in more detail, then: a square button will appear on your screen, when you click on it, you will see options for actions. There are initially six options, volume + and -, screen lock, screen rotation, sound off. and further". The last section also contains an additional menu.

So, to activate the application, go to the following tabs: "settings" - "basic" - "universal access" - "AssistiveTouch".

All other methods involve the intervention of the service center master, I can only briefly describe what needs to be done. If you decide to replace the button yourself, then the first thing you need to do is order the spring mechanism of the button with a train, these are the components that are out of order.

When the parts are on hand, you can start disassembling the iPhone, this process is also associated with some difficulties and is not at all like smartphones from other brands.

Hello. It's time to tell you my iPhone lock button breakage history... You will laugh, but I still have an old iPhone 4S brought in by an employee from Canada. My iPhone has served for 4 years and still works flawlessly. True, there was one case when the POWER button simply stuck (stopped pressing) and I could not use the phone normally. Today I will tell you how to overcome this fairly common disease. This story is from the happy end series ... So read the article until the end.

I was not the first and will not be the last iPhone user to encounter iPhone buttons not working. In this case, there are cases of failure of both the lock (power) buttons and the volume buttons (plus or minus). It is also worth noting that the buttons break on absolutely all iPhone models.

• How to replace the iPhone screen with your own hands - instructions

What leads to their failure? It is difficult to give an unequivocal answer here ... It may be the iPhone's fall on one of these buttons, or it may be pressed hard, or it may be just a marriage or poor-quality iPhone components.

Finding myself in a situation where one of the most strategic buttons on the iPhone stopped pressing, I decided to get to the bottom of the problem and fix the lock button on my own. Well, or at least try to fix it ... More on this in the next paragraph.

Why does the lock button get stuck on some less fortunate devices? The answer lies in the bowels of the iPhone and is related to “physiology of structure”Button mechanism.
The button itself (what we see on the end of the iPhone) cannot break as it is just a piece of aluminum. But under the button there is a so-called loop with miniature spring contacts, which fail.

The picture above shows a spring-loaded contact with a small black plastic “pimple” in the center. It is this very pimp that is the cause of all the troubles.The fact is that over time (perhaps after a strong pressure or blow) this small black bump may crumble or fall off, and without it the button will no longer function.

That's the whole breakdown. Now the matter is only in the way of repair. It all depends on how much you are willing to fork out or perhaps want to make repairs yourself.

There are many instructions on the Internet about “How to fix iPhone lock button ...", but almost all of them deceive users and boil down to a temporary replacement of a button with an iOS software feature... Apparently the Cupertinians initially knew that the problem with the buttons was quite possible, and added to Settings> General> Accessibility paragraph AssistiveTouch... After activation, a square button appears on the iPhone screen, which has many functions.

One of the functions is called "Screen lock"(Found in the subcategory"Apparatus") And essentially performs the action of the iPhone lock button.

Actually, this is a temporary solution, which many are successfully using. Naturally, the physical button will still be inoperative, and in order to really fix it, read the next paragraph.

Let me remind you that the lock button stopped pressing after a small plastic bump crumbled (fell off, etc.) ... Well, you remember (see photo above). There are only two options to troubleshoot this problem:

• replace the train entirely
• repair the existing loop

You can replace the loop on which the lock button is located at the service center, or you can do it yourself. If you are straight-handed enough and have the necessary tools, you can try to save money. IFixit.com has detailed instructions with photographs for disassembling almost all Apple equipment and not only. You can buy a flat cable for your iPhone model in China on AliExpress.com (or another website), but from personal experience I can say that the part MAY come originally non-working... The fact is that on the same loop with buttons there are also other elements - sensors or switches.

Apparently, the Chinese are not very good with quality control yet ... So I bought a cable to replace the volume buttons on the employee's iPhone 4S (the “+” button did not work for him). According to the instructions from the site iFixit.com made a replacement (it took about 1 hour in time), and as a result I got a working “+” button, but not working “-“ and a headphone jack. Fortunately, I did not damage the original cable during disassembly. I had to install it back and resort to the option to repair the original loop.

Repair of the loop, or rather the spring contact of the button, consists in restoring the microscopic tubercle. What have I done? I took a sharp blade and cut a bump from the Chinese train, and then glued it with “superglue” in the right place on the original train. You must be extremely careful and precise in your movements, because the parts are really VERY tiny.

On the AliExpress website (here) I bought ten spring contacts and now use them as donors to get plastic tubercles: o)

This is how I restored the power button and volume “+” button in two different iPhone 4S. ATTENTION: If you have never repaired anything in your life before, it is better to contact a specialist.

Well, and "a photo on a horse" ... The operation was successful, the patient was satisfied ...

Repairing the lock button on iPhone 4s is not often required, despite being one of the most used buttons on the device. The reasons for the failure of the lock button are not quite standard:

• Liquid ingress
• Overheat
• Shock or other mechanical damage
• Wear over time

It is not worth delaying the replacement or even diagnostics of the lock button, because we use it not only to turn off the phone, but also, for example, to take a screenshot of the screen (simultaneously holding down with the central key), set a silent mode during a call (single press), drop the call (double tap), to go to the desktop instead of the application (single tap during notification).

Repairing the iPhone 4s power button does not mean replacing the button as such, but working with a loop, on which the spring contacts fail.

There are three types of loop faults: contact disconnection, track break, burnout. AppleService specialists will diagnose the device for free and tell you which type of iPhone 4s on / off button repair is needed in your case.

The power button can fail for several reasons. One of them is the service life and the intensity of operation. Like most mechanical devices, a button has a certain number of presses, after which it may stop working.

IPhone users can confidently say that they have purchased a really high-quality device. Smartphones almost never fail, they work clearly and correctly. But, unfortunately, even they are not immune from the occurrence of some malfunctions. Most often, iPhone breakdown occurs through the fault of the user himself. The most common cause of breakage is when the device is dropped to the floor or into water. Of course, given the cost of the phone, there is cause for concern. But still, you shouldn't lose your composure, you need to grab the phone and just take it to the service center.

After prolonged use or mechanical damage, the smartphone's power button may fail. As practice shows, this happens more often for the second reason. But, nevertheless, if you notice that the screen does not lock or the button does not immediately work, then it is better to check the device by taking it for diagnostics. Today, iphone 4s and models of other generations are repaired by many service centers. They can be found on the Internet or by contacting the store where the smartphone was purchased: there you will definitely be prompted by the warranty service.

The power button can fail for several reasons. One of them is the service life and the intensity of operation. Like most mechanical devices, a button has a certain number of presses, after which it may stop working.

Another common cause of breakage is shocks or water getting into the phone. To protect your smartphone from mechanical damage, it is recommended to use a case.

If your smartphone has fallen into the water, then you do not need to try to dry it yourself, this is unlikely to bring positive results, so take it to the service center right away. If you postpone the repair, after two or three days the contacts in the smartphone will begin to oxidize. In this case, subsequent repairs run the risk of becoming not as effective and inexpensive as with timely treatment.

Sometimes the power button may not work right away due to a poor charge. Therefore, before going to the service center, it is recommended to put the device on a long charge, for example, for a day. If the phone still does not turn on after doing this, you may need to replace the button and check the software.

In any case, whatever breakdown is detected, experts advise to undergo diagnostics. Timely checking and troubleshooting will help not only extend the life of your smartphone, but also save money on repairs and delay the need to purchase a new model.

In this case, it should be attributed to service center for the repair of cell phones, where the replacement will be carried out competently and quickly. Moreover, the repair of iPhones in Novosibirsk is carried out in many service centers. However, if there is time, desire, necessary tools and spare parts, then iPhone button replacement can be done independently.

This article provides step-by-step instructions on how to replace a broken part yourself. In this case, the loop is subject to replacement, due to which the on / off does not work. But before you get started, you should evaluate all your chances of success and read the warnings.

1. Loss of bolts;
2. Loss of small parts;
3. Loop rupture;
4. Damage to any parts;
5. Installing the wrong screws in the holes.

These are just the most common troubles that can arise during work, since in order to get to the cherished goal, you need to remove a lot of parts. So if button sinks on iPhone, and there is a desire to replace it with your own hands, then carefully study the instructions.

This photo shows the defective iPhone 4 power button.

Here you can see the difference between a good and a damaged key. As you can see in the photo, the broken one (on the right) is more immersed in the communicator body than the working one.

First you have to remove the back cover. To do this, unscrew all the bolts holding it.

Next, we move the panel. It is important to place unscrewed parts and fasteners next to each other so that they can be reassembled correctly.

After the panel is removed, proceeds to disconnect the battery. First, unscrew the battery contact, which is located at the bottom of the smartphone to the left of the battery.

Now we disconnect the motherboard from the power supply and disconnect the battery from the connector. We must not forget that there is also a contact on the back panel here, so it is important to be as careful as possible.

Then we dismantle the battery.

To get closer to iPhone 4 button, you should unscrew the bolts securing the lower cable. You won't have to shoot him.

We peel off the cable and move it aside so as not to damage it inadvertently, and also so that it does not interfere with further parsing.

Now we turn to the upper trains that stand in the way of the cherished goal. We unscrew the screws and remove the protection.

This photo shows the cables already disconnected.

Now we remove the SIM card slot. To do this, insert a special tool into the hole on the slot and press. Sim-holder should jump out at the same time.

Now we disconnect the GSM antenna.

It's time to unscrew the device's motherboard.

Please note: In this photo, the screwdriver is pointed at the moisture indicators. There is a bolt under one of them, which must also be unscrewed.

When removing the camera, you must also pay special attention not to smudge it, otherwise the quality of the pictures will deteriorate in the future.

We remove the motherboard. You need to be as careful as possible with it, since this is the main part of the iPhone. If you damage it, then telephone repair will end up with the device becoming unusable.

This photo shows the location iPhone buttons... But in order to dismantle it, you must disconnect it from the system.

To get close to the loop, we also uninstall the speaker.

The tweezers point to where the bolts holding the push rod are.

After the fasteners are removed, you need to remove the part of the loop with the key.

Then you need to remove the part with the microphone.

This is what a disconnected ribbon cable looks like.

This is what the pusher itself looks like.

The analysis is over. Now you should replace the broken part with a new one, and assemble the device in the reverse order. This picture shows all the details that should remain after all the manipulations.

Have iPhone power button replaced, and now there will be no problems while using the gadget.

After reading this instruction, you can get to work. It would seem that to replace the key does not require much effort, but the peculiarity of the iPhone's design requires a lot of actions, and it will have to be disassembled almost completely. So if iPhone button broke, it is better to contact service center for the repair of mobile phonesand we'll fix it!

Structurally, the buttons - off / blocking, volume, Home - consist of an aluminum insert, with which there is direct interaction, and a spring-loaded contact located under it with a tiny plastic pusher.

• Destruction of the plastic pusher. The button sinks into the body of the iPhone, although it can continue to work when you press the button with force.
• Damaged spring-loaded contact. The button sticks, as in the first case, but does not work even with strong presses - you will also need to replace the home button on the iPhone 4.
• Malfunction of the connecting cable that occurs when disassembling / assembling the iPhone 4. Manifestation - the volume buttons do not work.
• Breakage of the insert. Because of it, the Home button is poorly pressed, which breaks off the protruding parts of thin plastic that hold it in the exact position.

The iOS arsenal contains functionality that allows you to solve the problem of broken buttons on an iPhone. The solution is in the “Settings”: go to the “Basic” menu item and then - to the “Universal Access” section. When Assistive Touch is enabled, a virtual button appears on the screen that calls up a menu that repeats the hardware buttons on the device. The position of the button is changed by holding and dragging it. The function will allow you to lock the device without pressing the shutdown button and return to the main screen if the home button on the iPhone does not work.

To begin with, you should visually evaluate and understand why the button may not work. You need to disassemble the phone and get to the necessary part.

1. Remove the back cover by unscrewing the two screws on the bottom of the iPhone 4 and pushing it up. You will need a Torx screwdriver (aka "star").
2. To continue replacing the iPhone 4 power button by unscrewing the metal cover and disconnecting the corresponding ribbon cable, you must carefully remove the battery glued to the double-sided tape. You will need an appropriately sized standard Phillips screwdriver and a flat blade.
3. Sequentially unscrewing the screws and disconnecting the cables so as not to damage them when dismantling the modules, get to the desired module.
4. If the Home button does not work well, you will have to remove the display module from the iPhone frame to access it. To do this, after removing all the modules and the motherboard, you need to unscrew 6 screws in the side parts and 1 screw each in the corners and remove the screen, making sure that the cables coming from it are not damaged.

Attention! When assembling the phone in the reverse order, be extremely careful when tucking the cables from the screen assembly into the smartphone frame so as not to damage them by pulling the screen to the body.

If the pusher is broken, you can perform such a procedure as replacing the power button on the iPhone 4 by replacing it or by resorting to a trick - glue a piece of plastic of the same size to the contact with a small amount of superglue.

A broken spring contact or a torn iphone 4 flex cable can only be replaced with the module on which it is installed.
