Why does the blue screen turn on on iPhone? What to do with the Blue Screen of Death on iPhone? Iphone 5s lights up blue screen and reboots

Some iPhone 5S owners have complained online that a blue screen suddenly appears on their device, and then the smartphone reboots without warning. In addition, the so-called “blue screen of death” or BSOD (Blue Screen Of Death) appears for some, even if no one is touching the phone at that moment. Most likely, the cause of the “blue screen of death” on the iPhone 5s is the new hardware (64-bit processor architecture) rather than some defective parts.

After studying this problem, I decided to collect everything possible methods its treatments, ranging from the simplest to the less pleasant.

1. If the iPhone 5S showed you a blue screen and began to constantly reboot with a blue screen, then you need to turn it off and reboot manually.
Treatment: simultaneously press and hold the On button for about 10 seconds. And Home button(which has a fingerprint sensor). This reboot can be repeated several times until the iPhone boots up. For example, I pressed these buttons right during the blue screen and everything was ok.

2. For many, the screen of death appears only when working with certain applications, both standard (Keynote, Pages and Numbers) and those purchased from the AppStore (various games and programs).
This suggests that, unfortunately, these applications are not fully optimized to work with the new processor.
Treatment: It is enough to wait for the update of both iOS itself and the individual applications with which the problem occurs, and for the developers to hurry up, report the problem in the comments to the application in the AppStore.

3. Sometimes, the iPhone may reboot after several unsuccessful fingerprint entry methods.
Treatment: Try disabling fingerprint unlocking and leaving only entering the password, or disable the locking function altogether. Restart your smartphone. If this method helps, then it’s worth installing latest firmware(it's always better to install the latest update via the cloud or iTunes help), most likely Apple will release the necessary fix in one of the updates, if they haven’t already.

4. Some users find it helpful to disable the Find My iPhone function, which itself sometimes appears background performs manipulations to determine the location, which causes a blue screen.
Treatment: Go to Settings - iCloud - Find My iPhone and turn off this feature. Restart your iPhone.

I hope one of these methods will help you, but what helped me was that I simply stopped running several applications, when launched, the iPhone 5S kept rebooting.

Blue screen on iPhone 5S is not new. Many owners encounter this problem on their Apple gadgets. It is noteworthy that the previous generation of phones (iPhone 4, 4S) worked properly, and this happened to them extremely rarely. But 5, 5s, 6 and 6 Plus have become problematic gadgets. They are the ones who are in the risk zone.

Symptoms

The symptoms of this breakdown can be completely different, but the result is always the same - a non-working display. Most often, on the iPhone 5S, the apple lights up, then the blue screen, after which the device does not respond to presses. In this state, it cannot be used in any way: neither reset the settings nor reflash it.

Causes

There is no specific reason why something like this happens. This malfunction may be associated with improper operation of the phone, its fall, failure of any part, incorrect replacement of a spare part in a service center, etc. Often on the iPhone 5S, a blue screen appears as a result of an attempt at self-repair. Users unknowingly open the cover, and under it there is a thin cable. If you break it or break contact, this may well lead to a similar result - a blue screen on the iPhone 5S and a reboot.

Users state that the screen may or may not work. This suggests that the contacts can be connected to each other (the screen is working) and disconnected (the screen is not working), for example, in any position of the device or at a certain temperature. Often, if you put the device in the freezer, the restored iPhone 5S can be taken out after 5-10 minutes. Under the influence of temperature, the contacts can connect in some way, but this does not last for a long period of time.

What to do?

Like any other equipment, iPhones also break down, and if this happens, you need to contact service center. Although this is trivial, it is often impossible to do without service centers. But you can also try to fix the gadget manually. So, let's say you see a blue screen on your iPhone 5S. What to do and how to solve this problem? The very first and obvious action is to try to reset the login to your account. It rarely helps, but you have to try. This is done by connecting the gadget to the computer and using iTunes.

Will reflashing help?

Most likely, a miracle will not happen, and the problem will not be eliminated. Therefore, flashing the device is shown below. A small percentage of iPhones came to life precisely after flashing. But you need to understand that the firmware decides software problems, and the blue screen is most likely related to the hardware. Therefore, it is possible that after flashing the blue screen on the iPhone 5S it will make itself felt again even if the firmware helps.

The next method is to check whether the top cable is secured correctly. Often this is where the cause of the problem lies. This cable is located in the front area front camera and proximity sensor. Of course, for this you will have to spin up the device, but there is nothing difficult about it. All you need is a special small star screwdriver.

Usually the problem is in the cable: it could come off as a result of the phone falling. Also, when replacing the display, the service center may have mixed up and swapped the mounting bolts (they are different sizes). As a result, the contacts of the cable do not fit tightly to the motherboard phone, which may cause a blue screen.

After removing the cover, these bolts can be easily swapped, then the cable will be pressed tightly with the contacts to the board, and the problem will be solved. But this is already a hardware repair, and if you have no experience at all in disassembling phones, or you do not understand what a cable is and what it is needed for, then it is better not to try to repair a smartphone yourself.

Hard case

The problem may not be in the cable at all. As a result of overheating, dropping the phone, or careless use of a soldering iron, the microscopic channels on the motherboard could be damaged. It is impossible to diagnose this yourself without knowledge and special equipment, so only a specialist should do this. He will be able to identify problematic channels and restore their conductivity. But even he can’t always figure it out and repair the device.

If you are unlucky and the problem is not in the cable, then you will not be able to do anything on your own. Take the phone to be repaired and after repair, try to sell it. Often after such repairs they try to “fuse” the phone. After all, a restored iPhone 5S after the “screen of death” almost always breaks again. Not immediately, of course, but over time.

How to avoid such a breakdown?

The advice will be banal, but effective. It is a mistake to believe that Apple technology is perfect. Yes, the production process is technologically advanced, and the company really makes reliable equipment, but even it can break. Dropping your phone on a concrete slab, asphalt or stones is all detrimental to anyone modern smartphone. What can we say about water getting inside or the device falling into a puddle?

So you should handle the phone very carefully, given its high cost and lack of protection from water and dust. This iPhone 7 and 7 Plus can be dropped into water (and then to a shallow depth), because it is not dangerous for them thanks to IP67 (or IP68) protection. By the way, the iPhone 7 and 7 Plus do not have this problem with the screen, which is worth paying attention to.

Finally: even if you encounter a blue screen on your iPhone 5S, you shouldn’t be upset. There are no phones that never break. And the problem of the blue display itself is not critical: it is almost always possible to bring the phone back to life, with the exception of very sad cases when the blue display is not the only and, perhaps, not the most serious problem.

The above methods help in some cases, but not always. But the service center will probably be able to solve the problem, albeit for money. But if the phone is under warranty, then you don’t have to worry at all.

This article is devoted to the problem on the iPhone 5S or 6, when after an unqualified repair (usually replacing the display or battery), the device stops booting.

Symptoms:

- at turning on iPhone an apple appears and everything stops there, the device just hangs on the apple, nothing happens
- when you turn on the iPhone, an apple appears, after a while the device reboots and so on endlessly
- when you turn on the iPhone, an apple appears, then the screen turns blue, the device reboots, and so on in a circle

If your iPhone behaves this way, and it started after replacing the screen or battery (the most common) or other spare part, then, with a high degree of probability, the malfunction is caused by improper assembly. The fact is that the cover that presses the display cables is screwed onto 4 screws (iPhone 5S) or 5 screws (iPhone 6) (see Photo 1), and these screws have different lengths (the short ones are circled).

If you screw a long screw into the place where there should be a short one, it will cut into the printed circuit board and damage the traces (see Photo 2). Depending on the force applied, the depth of the screw into the board and the degree of damage may vary.

The solution is very delicate work, where the broken tracks are restored using a very thin conductor (see Photo 3). I apologize for the quality of the photo. But the general meaning is clear.

Please note that it is not always possible to restore a printed circuit board after such damage. Printed circuit boards are multi-layered. If you twisted it “from the heart” and the screw cut very deeply, then restoration may be impossible.

It so happened that the leading iPhone model Apple's 5s brought with it not only a powerful, cutting-edge processor, a fingerprint scanner and an improved camera, but also some glitches.

Dozens of topics on the official Apple resource and other Internet resources about the iPhone5S are devoted to unexpected reboots. Many owners of this top model noted that the problem appears the very first time after purchasing a smartphone.

The symptoms of this failure are as follows:

first the appearance of a blue screen;
rebooting the smartphone without prior warning. Often a blue screen of death (BSOD) appears on a non-working phone.

Apparently, the blue screen of death on the iPhone 5s is not very critical and dangerous, and this is most likely due to the new hardware (64-bit processor architecture), and not to a hardware failure.

It is worth noting that “blue screens of death” also happened on previous generations of iPhone, but then their causes were purely hardware problems of iOS devices. iPhone owners 5s suffering from the blue screen of death, for now we can only wait for a solution to fix the problem from Apple and mobile developers.

Possible reasons

There are several reasons why the Blue Screen of Death appears.

Let's take a closer look at them:

Errors that cause BSOD are mostly software in nature. In general, according to unconfirmed information, software The iPhone 5S crashes twice as often as the operating system of earlier models. Although there is no need to worry too much, since we are talking about a few cases out of a thousand.

Solution

The appearance of the blue screen of death and its subsequent reboot are not the most pleasant symptoms in the operation of this top-end smartphone. There is no need to contact a service center for help, since it is not at all difficult to get rid of such problems yourself.

Let's describe the most effective steps to fix the BSOD problem:

reboot the phone. To implement this, press the Power and Home buttons for 10 seconds. The smartphone will turn off. This reboot can be repeated until mobile devices will not load;
turning off the smartphone for 5-10 minutes and then turning it on;
Turn off apps like Keynote, Numbers, and Pages from syncing with iCloud. It has been noticed that the iPhone crashes when switching from one program to another, which indicates certain problems with multitasking;
when new version iOS install the update, or update it yourself software, the operation of which led to the occurrence of BSOD. This treatment is relevant in a situation where applications are not fully optimized with the new processor;
The problem caused by unsuccessful fingerprint input is solved by disabling the corresponding input and restarting the iPhone. In a situation where normal operation resumes, you need to install the latest firmware version (cloud or from iTunes), since there is a high probability that Apple will release the required fix in one of the updates;
It often helps to disable the iPhone search function, which periodically performs certain actions in the background to determine the location, which is the reason occurrence of BSOD. To disable this function, you need to go to “Settings - iCloud - Find iPhone” and move the slider, after which you should reboot the device.

One of the described methods will almost certainly solve the problem of the blue screen of death appearing on your iPhone 5s and will allow you to continue to enjoy the unsurpassed advantages of this gadget.

Thus, the “blue screen of death” BSOD on the iPhone 5s, as on other Apple devices, is only a temporary problem that will soon be eliminated by updating the operating system as a whole, its set standard programs, as well as numerous third-party applications.
