The blue screen on the iPhone 5S is not news. Many owners experience this issue on their Apple gadgets. It is noteworthy that the previous generation of phones (iPhone 4, 4S) worked properly, and very rarely this happened to him. But 5, 5s, 6 and 6 Plus have become problematic gadgets. It was they who came from the risk zone.
Symptoms
Symptoms of this breakdown can be completely different, but the result is always the same - a non-working display. Most often, an apple burns on the iPhone 5S, then a blue screen, after which the device does not respond to pressing. In this state, it cannot be used in any way: either reset the settings or reflash.
Causes
There is no definite reason why something like this happens. This malfunction may be due to improper operation of the phone, its crash, failure of any part, incorrect replacement of a spare part in a service center, etc. Often, a blue screen appears on the iPhone 5S as a result of an attempt to repair it on its own. Users unknowingly open the lid, and under it is a thin ribbon cable. If you cut it off or break the contact, it could very well lead to a similar result - a blue screen on the iPhone 5S and a reboot.
Users say that the screen may or may not work. This suggests that the contacts can be interconnected (the screen works) and disconnected (the screen does not work), 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 removed after 5-10 minutes. Under the influence of temperature, the contacts can connect in some way, but this is not for a long period of time.
What to do?
Like any other technique, iPhones also break, and if this happens, you need to contact a service center. Although this is commonplace, often service centers are indispensable. But you can also try to fix the gadget manually. So, let's say you saw a blue screen on the iPhone 5S. What to do and how to solve this problem? The very first and obvious step is to try resetting your account login. This rarely helps, but you need to try. This is done by connecting the gadget to a computer and using iTunes.
Will flashing help?
Most likely, the miracle will not happen, and the problem cannot be fixed. Therefore, the following is a flashing of the device. A small percentage of iPhones came to life precisely after a flashing. But you need to understand that the firmware solves 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 will again make itself felt even if the firmware helps.
The next way is to check if the upper loop is fixed correctly. Often in it lies the cause of the problem. This loop is located in the area of the front front camera and proximity sensor. Of course, for this you will have to untwist the device, but there is nothing complicated about it. Only a special small star screwdriver is needed.
Usually the problem is precisely in the loop: it could move as a result of the fall of the phone. Also, when replacing the display in the service center, they could confuse and interchange the mounting bolts (they are of different sizes). As a result, the loop contacts do not fit snugly on the phone’s motherboard, which may cause a blue screen.
Having removed the cover, these bolts can be easily interchanged, then the cable will be pressed firmly by the contacts to the board, and the problem will be solved. But this is already hardware repair, and if you don’t have any experience in disassembling phones at all, or if you don’t understand what a cable is and what it is for, then it’s better not to try to repair your smartphone yourself.
Hard case
The problem may not be in the loop at all. As a result of overheating, a fall of the phone or careless work with a soldering iron, the microscopic channels on the motherboard could be damaged. It is impossible to diagnose it 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 not always figure out and repair the device.
If you are not lucky, and the problem was not in the loop, then you yourself can not do anything. Carry the phone in for repair and after restoration try to sell it. Often after such a repair, they try to “fuse” the phone. After all, the restored iPhone 5S after the "screen of death" almost always breaks down again. Not immediately, of course, but over time.
How to avoid such a breakdown?
Tips will be commonplace, but effective. It’s a mistake to think that Apple’s technique is perfect. Yes, the production process is technological, and the company really makes reliable equipment, but even it can break. A phone falling onto a concrete slab, asphalt or stones - all this is detrimental to any modern smartphone. What can we say about getting water inside or dropping the device into a puddle.
So you should handle the phone very carefully, given its high cost and lack of protection against water and dust. This iPhone 7 and 7 Plus can be dropped into water (and even to a shallow depth), because they are not afraid of it thanks to the protection of IP67 (or IP68). By the way, the iPhone 7 and 7 Plus do not have such a problem with the screen, which is worth paying attention to.
Finally: even if you encounter a blue screen on the iPhone 5S, do not get upset. There are no phones that never break. And the problem of the blue display itself is uncritical: it is almost always possible to bring the phone back to life, except in very sad cases when the blue display is not the only and, possibly, not the most serious problem.
The above methods help in some cases, but not always. But in the service center they will probably be able to solve the problem, however, for the money. But if the phone is under warranty, then you don’t have to worry at all.
