Technical shortcomings of all generations of iPhone. Dust on iPhone camera

Six months ago, I noticed a problem in pictures taken on my iPhone. Various photos were marked with a spot in the same place in the frame. Having carefully examined the glass above the microscopic camera lens, I found a small speck of dust and removed it by tapping the body with my hand.

After some time, there was so much dust that it became physically impossible to take normal pictures. I turned to a specialized service to not only fix the problem itself, but also to find its underlying cause. As it turned out, the matter could not be limited to simply cleaning the glass. Over the past year, a lot of dirt has accumulated inside, and your situation is most likely no different from mine in better side! You just don't know about it yet.

For answers to my questions, I turned to the MacPlus.ru service. The guys were invited to their workshop to show and tell where the dust inside the case comes from and how to properly remove it. Homemade tools are not suitable for this at all. Neither cotton swabs, nor, especially, a vacuum cleaner pipe will lead to the best results. Before this, I gave my smartphone twice to “home-grown” craftsmen, and each time after that the dust appeared again, literally after a few days.

A master named Alexander began the process methodically: this is not the first time they have had a device with such a problem, not the tenth, or even the fiftieth. Not much changes from generation to generation of Apple smartphones: the iPhone was never completely sealed, and therefore the pristine purity of its internal components is only a temporary phenomenon.

We're dealing with an iPhone 5, which means the disassembly process starts with unscrewing the bolts next to the Lightning port. These microscopic screws are as easy to lose as it is difficult to find an ordinary screwdriver for them. By the way, we are dealing with the standard , and its special variety TS1. To do this you will have to purchase a special tool.

And here it goes further important point, allowing you to distinguish a real professional from a “home-grown” expert who learned on roller skates with YouTube. Under no circumstances should the display be disconnected from the main part using a suction cup. Careless use of force leads to the detachment of glass from the display module, which turns the entire “sandwich” into an unusable set of hardware. If one day after repairs you notice that streaks or tiny bubbles have appeared under the glass above the screen, you are faced with the work of an amateur.

We lift the screen module and see an extremely sad picture. I've been using my smartphone for a little over a year, but I've never placed it in dusty places, hidden it under a dusty pillow, or kept it in my jeans pocket for long periods of time. But somehow the dust has accumulated, and it’s not just a lot of it. If I were the master, I would have grinned, but, as it turned out, all this is an absolutely ordinary picture. The only difference is that someone is lucky and the dust does not get on the glass above the camera module longer.

To assess the full extent of dust pollution, motherboard iPhone 5 electromagnetic protection is removed. It also partially stopped the spread of particles. As luck would have it, the outbreak fell on the camera, and it didn’t just happen.

According to the technician, the problem could have appeared after the smartphone fell onto a hard surface. In such cases, the relative tightness of the rim around the screen could be compromised. And slowly, particle by particle, the entire upper, inner part of the case was filled with dust. So why did previous calls to other service companies not bring the desired results? It's just that the cleaning was most likely done manually.

All bolts and elements of the smartphone are placed in a tray with cells. Losing any of the spare parts is disadvantageous, first of all, for the mechanic himself: a second such spare part is not always available. God forbid you lose any of this at home, not to mention damage to some cable. And there are a lot of trains here.

Having removed all loose elements, Alexander takes a powerful air blower powered by a compressor. Without such a thing, it is almost impossible to get rid of dust in the case. By intelligently adjusting the power of the air flow, you can remove all the dirt from sensitive electronic components without damaging any of them. The process takes almost a minute. Immediately after this, the smartphone looks like new - compared to what it was before. But we're not done yet.

Since dust has probably gotten on the optics in the camera, you will have to carefully clean them too, and at the same time go over the glass inside with a cotton swab. Pay attention to the size of the flash: its power, sufficient to illuminate dark rooms as a flashlight, does not in any way correlate with the microscopic size of the module. And there is also a lot of dust on it. Time for handmade work, and very careful work at that.

After walking with a cotton swab along the inner wall of the back of the case, the master begins assembling the smartphone. The parts fit into place in the reverse order, carefully and without haste. Trembling hands are the most terrible enemy in this matter. Calmness during this process makes the difference between a barely noticeable “click” of an inserted cable and a broken pad.

The iPhone was dirty and dusty. It became clean. The whole thing took about 5 minutes. The remaining fifteen I looked at the “insides” of the device. Say what you like, but only Apple knows how to make hardware as well as the design of the case. Black motherboard, strictly arranged main chips, incredible density of components per millimeter. Alexander also agrees: other manufacturers almost always ignore everything that is not visible to the average user. It is for this attention to detail that we love the products of the Apple company.

It all started with two bolts, and it all ends with two bolts. The screws are put into place, the smartphone is turned on and the camera is checked. In principle, this is not necessary. Just look at the camera again and see the huge difference.

Some time after purchasing a smartphone, quite often a problem is discovered: in pictures taken with an iPhone, there is an inexplicable smudge in the same place in different frames. Taking a closer look at the small iPhone lens, you can recognize a speck of dust under its glass. Removing it will not be difficult; just tap the body with your finger.

After some time, there will be so much dust that taking pictures will become simply unrealistic. In this case, tapping, unfortunately, is no longer sufficient. A huge amount of microscopic dust has accumulated inside, which cannot be easily removed.

There is dust in the iPhone 5 camera - it won't be difficult to remove it

Bayon specialists want to tell smartphone owners about operating system iOS, where the dust inside their devices comes from and how to remove it from there. None of the available tools that you find at home are suitable for these purposes, and the vacuum cleaner pipe is completely out of the question.
Remember that if you decide to open the iPhone case yourself, the device will be removed from warranty. Here you will have to make a choice in favor of one of two options: solve the problem yourself or have your smartphone repaired and cleaned at a service center.

Apple products cannot be called completely sealed. Little changes in their design from model to model. Therefore, it is only a matter of time before your smartphone becomes clogged from the inside.

How to disassemble iPhone 5

First you need to unscrew the bolts. Yes, exactly those bolts that are located next to the Lightning port.

As you have already noticed, standard screwdrivers will not fit such bolts. Moreover, they are very small, so you need to be careful not to lose them. To remove the smartphone case, you need to purchase a special tool: a screwdriver with the Pentalobe standard, or rather, its special variety TS1

When detaching the display from the case, the main thing is not to overdo it. Improperly calculated force may cause the glass to detach from the display module. After this, it will be impossible to use the smartphone.

After the screen module is lifted, you will see an unpleasant picture: dust in a huge number accumulated in the body. Even if it has not yet penetrated under the glass above the camera, it is only a matter of time, know that it is still already in the body of your device.

If you remove the electromagnetic protection from the motherboard, you will see how much dust has accumulated in your iPhone. Basically, thanks to electromagnetic protection, dust does not penetrate so much into particularly important parts of the device.

The camera, unfortunately, is not a place where dust does not penetrate. Experts claim that the problem of dust appearing in the case could have been caused by the smartphone falling. As a result of the impact, the seal around the display is broken. This is the reason why the iPhone gets dirty from the inside, but you can clean it yourself.

Be careful when disassembling the smartphone; for convenience, all bolts and parts of the smartphone must be placed in some niche. Losing any part will cost you a lot. Be careful not to damage the cables, there are a lot of them in the iPhone 5.

You can clean iPhone 5 from dust using a source air flow. It is necessary to adjust the air flow so that it blows away dust, but is not too strong. In this way, dust is removed from all surfaces of the device. Not a single part is damaged. This action will take no more than a minute, and the smartphone will again acquire a presentable appearance.

However, this is not the end of cleaning your smartphone from dust. The main task is to remove dust from the camera, and we haven't done that yet.

This is where cotton swabs come in handy. Use them to clean the camera optics from dirt. You can also wipe the inside of the display with a cotton swab.

You need to reassemble the iPhone in reverse order. The main thing is not to rush and not to worry, and then everything will work out.

A short video to help:

At all Apple presentations we are told that the new iPhone is perfect, that it is better than previous models and competitors. This often turns out to be the case, but alas, there were, are, and I think there will be problems with the technical part. In this article we will look at the most common problems associated with each generation of Apple phones.

iPhone 2g - non-separable

In principle, it didn’t have any technical problems - after all, the phone was developed for 2.5 years under the strict control of Steve Jobs. But in the future, one annoying fact was revealed - the phone was practically inseparable: the metal cover was removed with great difficulty, and the battery was tightly glued, and it was impossible to remove it without damage. Less significant problems include a scratched back cover: alas, they didn’t yet know about anodizing aluminum, so after a year of wearing the phone without a case, it took on a life-worn look:

iPhone 3G/3GS - cracks on the cover

The problem with Apple's abrasive cover was solved simply - they replaced it with a polycarbonate one. Yes, now the lid has not lost over time appearance(however, scratches on the plastic are visible only if you look closely), but another problem appeared: due to the fact that Apple did not reinforce the 30-pin and 3.5 mm connectors with metal, the plastic next to it cracked very quickly, no matter how carefully the owner used them . No problems with technical side this did not lead to anything - it just spoiled the aesthetic pleasure of using the device. The strangest thing is that even a year after the release of 3G, in 3GS, the same problem remained.

iPhone 4 - "antennagate"

In my fourth Apple smartphone I decided to return to metal. Only now it was steel, and to prevent the device from becoming too heavy, the back cover was made of glass. As you might expect, this increased the fragility of the device: now almost any drop resulted in a cracked glass either on the front or back. But the main problem that surfaced even before this is “antennagate”. Its essence is that simply holding the phone in your hand could seriously reduce the signal cellular network. This arose because Apple decided to withdraw WiFi antennas and cellular network on the metal inserts on the sides, and for some reason did not insulate them with varnish:

So, when you took the smartphone in your hand, the antenna shorted to the body, and the signal could disappear altogether. The company's behavior here was extremely strange: at first Apple wrote that this was just a software glitch that would be solved by updating the software. This update actually came out, and now the network indicator showed a good signal even when there was none. Of course, it was still impossible to call, and the company still had to admit that the problem was “iron” and start distributing rubber bumpers, which, by the way, they had previously intended to sell. Another funny thing is that such bumpers were distributed only in the USA; users in other countries had to buy them with their own money.

iPhone 4s - disposable battery

One of the least problematic iPhone models: The metal inserts were insulated, eliminating the "antennagate". The glass still broke when dropped, but this was clearly not Apple's problem. But their other “jamb” came out - since by 2011 the iPhone had already become the most popular smartphone in the world, queues lined up in front of stores on the day sales began, and in the first week the number of devices sold amounted to millions. To ensure the supply of such a number of devices, Apple decided to slightly shorten the production cycle, namely, reduce the time the display was exposed to ultraviolet lamps. Why was this even necessary? The display module is a sandwich made of protective glass with the touchscreen and the screen, and between them, to fasten them, a special glue is poured, which under the influence of ultraviolet radiation becomes transparent and durable. But to properly hold the screen under the lamp you need a day, which is a very, very long time for Apple. And the reduction in display illumination time meant that the glue did not always have time to dry, and some people received an iPhone with yellow spots on the screen (or, as in the photo below, with a yellowish tint):


Yes, it’s unpleasant, but it’s easy to treat (because this problem is still relevant today) - just walk around with the phone in sunny weather for a while, and the glue will dry and become transparent.

But the second problem was much more serious: Apple decided to fight Chinese counterfeit batteries. When installing such a battery, at first everything was fine - the phone worked fully and could even live longer than on the old original battery, but when flashing the firmware, the user was almost guaranteed to receive error 29 in iTunes. Alas, the only solution to the problem was to replace the battery with the original one, flash the firmware and change the battery back. A software solution to the problem was never found, although now it has almost disappeared, because new software for 4s has not been released for a year.

iPhone Five, Peeling

In 2012, Apple finally realized that a 3.5" screen for a smartphone was cool in 2007, but 5 years later it was already too small, and introduced the iPhone 5 with a 4" display. In addition, they decided to return the aluminum case, so now the chance of breaking the glass when dropped is halved. But another problem came - the paint was peeling off on the edges, while Apple convinced that it uses the anodizing process to apply the paint. Alas, there was no solution to the problem; Apple considered peeling paint a cosmetic defect and did not replace peeling phones. Considering that iPhone sales 5 lasted only a year, the problem was quickly forgotten.

But after some time, massive complaints about the battery began to appear, mainly from the owners of the first batches - that it did not hold a charge well. Alas, the problem turned out to be widespread, and Apple even opened a program for free battery replacement.

iPhone 5S - peel-off screen

The phone turned out to be extremely good, so initially all the problems were reduced to jangling buttons and yellow spots on the display - in short, ordinary nit-picking. But after six months or a year, a more serious problem appeared - on some devices the display in the upper right corner began to peel off. The investigation showed that there is physically little space for applying glue, so perhaps all 5S are susceptible to this. On the other hand, those who rarely play on a smartphone, do not keep it in the heat and do not create other conditions for the glue to dry quickly may not have encountered this problem even now, 4 years after the release of the device.

iPhone 6/6 Plus - bendable case

In 2014, Apple decided to follow the fashionable trend of increasing display size, and released models with 4.7 and 5.5" displays. But at the same time, the company forgot that if for creating a hard For a case for a 4" smartphone, a thin aluminum "body" is quite sufficient, where the side edges, rotated 90 degrees to the bottom, are responsible for rigidity, but for a 5.5" smartphone this will not be enough, especially since the angle of inclination of the side edges is by no means the required 90 degrees. . As a result, such a “shovel” was relatively easy to bend. Yes, many users quite reasonably wrote that the smartphone should be used, and not bent, and I would agree with them, if not for the problem that emerged later: nevertheless, slight bends of the case occurred on these models all the time, which led to slight deformations of the motherboard . And as a result, after a year or two, the touch simply stopped working, and a gray stripe appeared on the screen below. It would seem, how does this relate to the bending of the body? It’s very simple - the touch chip was located exactly on the bend line, which led to the fact that after some time it lost contact with the board, which led to the inoperability of the touchscreen. To Apple's credit, they still recognized the problem, and such phones are replaced under warranty.

The second problem with the long-suffering iPhone 6 Plus is the rear camera: in some devices it could produce blurry images. Apple also acknowledges this problem and replaces the camera under warranty.

iPhone 6S/6S Plus - many small problems

The devices were both successful and unsuccessful at the same time. On the one hand, the new 7000 aluminum alloy has given back cover serious rigidity, bending the iPhone is now impossible. On the other hand, many small problems have appeared: this is a garland of backlight lamps at the top of the screen (appeared due to the fact that the display module has now become thicker due to 3D Touch), and dust under the screen at the top left (again due to 3D Touch - they play the role of bellows, and air and dust penetrate into the layers of the display through the volume rocker), and the apotheosis - two processor manufacturers: Samsung and TSMC, and battles about whose processors are better are still raging on the forums. The problem with backlighting and dust was solved in new batches, and, it would seem, somewhere from the beginning of 2016, the iPhone could be taken without fear. But no - the problem with batteries has appeared again (well, Apple has no luck with them): now it manifests itself in the fact that the iPhone 6S can simply turn off even at 20-30% charge. Apple tried to solve the problem in software, but gave up and opened a battery replacement program. The problem was so widespread that employees of authorized service centers complained that all they did all day was change problem batteries.

iPhone Seven, Whistling

On at the moment The smartphone has no serious shortcomings (although they may appear in the future - after all, the model is only a year old). There are three most discussed problems: the first is whistling of the chokes when the processor is loaded. There really is a problem, moreover, it also exists on older models (6S, for example), but there is definitely no inconvenience from it, because in order to hear the noise, you need to run some benchmark on the device and put your ear to the back of the smartphone - Agree, not the most realistic use case. The second problem is the screen tint. Apple has used displays from different manufacturers, and they could be both warmer and colder, but this was visible only with direct comparison. In the iPhone 7, Apple switched to a new color space - DCI-P3: it is wider than the usual sRGB, and “jambs” of screens from different manufacturers can already be seen without direct comparison. Well, the third problem is the scratchy cover in shiny black iPhone versions. This is not a problem of Apple, but of technology - it is impossible to create a non-scratch shiny coating on aluminum (at least for now), moreover, Apple warns about this on its website.

As a result, as you can see, technical problems of one degree or another were present on all generations of the iPhone. Is this good or bad? Rather usually: modern smartphone consists of dozens of parts that interact with each other in various ways. And find everything possible problems It’s simply unrealistic; moreover, problems that may arise a year after using the device cannot be detected at all during tests. So the only way out is to just accept it and before buying new iPhone carefully study all the technical nuances with it, so that upon purchase you can immediately check whether there is a defect or not. Well, most serious defects are still covered by warranty or replacement programs, so users of PCT devices have absolutely nothing to worry about for two years.
