- Getting the insides of the phone wet;
- Poor contact of the cable;
- Poor quality assembly;
- Factory defect.
What to do if a breakdown occurs? In order to prevent the breakdown described in the first case, you must treat the device with care. You should install special glass that will protect against unnecessary scratches. If the gadget has fallen and a dark spot has formed on the display or a blue screen has appeared on the iPhone 5s, then you should immediately run to us, since such a breakdown can lead to a complete loss of functionality of the smartphone.
After heavy humidity, not only a white, blue, yellow or black spot may form, but it is also possible that the touchscreen will turn off partially or completely. And a solution such as rebooting will not help you. Because the malfunction is associated with a short circuit when moisture gets on the wires and cables. It can only be prevented by careful handling of the iPhone 4s, namely, do not drop it in water, do not use the phone in the rain or in places where there is a risk of moisture getting on the phone.
How to fix it
Disconnection or breakage of the cable occurs due to a fall or strong shaking. The touchscreen connector may simply become disconnected or broken off, and then it can no longer be repaired. And the only option to fix the problem and restore the sensor’s operation is to remove the old cable. Apple is good in terms of build, but the iPhone 5c is not able to withstand strong impacts, especially the newest “thin” generation. In this case, it is impossible to provide first aid, since the cable is located inside the screen. The first sign of a cable disconnection or poor contact is instability in touches and display responses or a complete lack of response to touches. To avoid disconnection, you should handle your phone carefully; there are also various cases that protect your iPhone 5c.
Sometimes, in order to fix a problem cheaply, workshops use low-quality spare parts (counterfeits). A non-original display may have manufacturing defects in the form of spots on the screens. The copy differs from the original in brightness; when you receive the phone, carefully check and compare the quality of the repair with the factory assembly. Use only highly qualified repair centers.

This morning I discovered a strange bug in my phone. It doesn't affect anything, but it hurts the eyes and it's annoying. I googled, but didn't find anything useful. Then I conducted a whole bunch of experiments, wrote a question on Twitter, community ru_mac and even called Apple technical support.
This morning this light appeared on the iPhone 5s (screenshots below the cut).
At first, this only happened when launching some applications through search, and they simply launched from the desktop without this light. Then I noticed that this illuminated strip also appears when the screen is unlocked. If you turn off parallax, this flare does not exist. You turn it on and it appears.
Resetting settings doesn't do anything. Full reset The problem seemed to be solved, but after 10 minutes of use it appeared again. I flashed it through iTunes from the file cleanly and did not restore the backup. At first everything was fine, but I installed a couple of applications and it all started again.
What could it be?
As a result, technical support asked a bunch of questions, but did not give any sensible advice, except for what I had already done myself. But the “almighty” Twitter solved the problem. It turns out I'm not the only one who encountered this bug.
The answer was suggested by @wylsacom, for which many thanks to him! Maybe it will be useful to someone too.
The white bar when unlocking is a software glitch in iOS 7.1 due to any (almost) white icon in the second top row. It can be treated by changing the location of the icons.

Imagine the situation: you recently purchased absolutely new iPhone and after several days of standard use, unpleasant yellow spots and stains suddenly appeared on its screen, especially noticeable on a white or light gray background.
At the same time, no “traumatic” or curious situations happened with the device, that is, there were no reasons for disruptions in the operation of the display.
Then why do yellow spots appear and how to fix it?
Why do yellow spots appear on the iPhone screen?
It is quite difficult to establish the exact cause of the described problem, but most often the adhesive used in assembling the module is to blame for the appearance of spots on the display. Although the company itself has not commented on user complaints, a number of experiments have shown that yellowish stains appear on the surface of the screen if the reagent used to glue the glass did not have time to completely dry and evaporate before the gadget was released for sale. In this case, all such manifestations should disappear after a few days if the device is placed in a warm and dry place. Also, the problem can resolve itself within several days of active use of the device.
Alas, the long drying period is not the only drawback of the fastening substance torn out by the Americans. For example, spots on the display may appear as a result of exposing the device to extremely high or low temperatures. That is, the screen can be damaged if you drop your iPhone in a snowdrift for several hours or forget it under the sun during the most active period of the day. The glue may also turn yellow due to a sudden change in the temperature of the external space. in case of yellow spots, lasts only 2 hours.
In addition to the problems described, the answer to the question “Why on iPhone screen Are yellow spots appearing? The most common occurrence of moisture getting inside the case may be. If water seeps under the display glass, it can disrupt the color matrix, causing it to stop displaying certain colors normally. Wetness also results in permanent multi-colored (including yellow) spots and stripes on the display.
In addition to the described factors, disruption of normal image transmission is influenced by software smartphone. For example, some “non-native” programs or applications for the camera can lead to the appearance of spots on the display, but most often such spots are non-static, that is, each time they have a different shape and appear on the screen. different places. Of course, mechanical impacts on the screen area can also damage the internal color display systems, which can lead to various spots, stripes and dots throughout the display.
If you notice a white spot on the iPhone screen, this indicates problems with its operation. Image defects indicate breakdowns of internal components and components. To determine the nature of the malfunction, you need to find out the causes of the stain on the screen.
An external examination and detailed diagnostics of the smartphone will allow you to determine the functionality of the iPhone. If you are familiar with the structure of modern smartphones, you can do this yourself. If stains appeared immediately after purchasing the phone, contact the service center for warranty repairs or replacement mobile device.
Causes of image defects
If white dots, black spots or white stripes appear on the iPhone screen, this means that the smartphone has been affected by negative factors. These include:
- software glitches
- mechanical damage (dropping the phone, pressing the touch screen hard)
- moisture ingress (contact with any liquids)
- factory defects (damaged pixels, stuck together sensor and display, illiterate LED assembly)
If cracks appear on the iPhone screen after a fall, then particles of dust, sand, and moisture can get inside the case through them. This will inevitably lead to defects in the operation of the backlight, and if the cause is not eliminated in a timely manner, such important parts as the matrix, touchscreen, and display will fail.
The ingress of moisture inevitably entails oxidation of parts. Problems with the screen may not appear immediately, but over time, not only stains, but also more serious deviations will appear.
Software failures that appear as spots indicate a failure of the microcircuit responsible for controlling the screen.

There are times when iPhone, iPad or iPod users encounter one of the problems with their device screens - dead pixels. It's worth remembering that there are differences between dead, hot and stuck pixels. There is also such a thing in the world as a group of defective pixels - this is the number of defective pixels in a square, the size of which is 5x5 pixels.
Dead pixels are pixels that do not light up in active mode. On a white background they resemble a black dot. And hot pixels are those that, when actively standing, look like white dots on a black background. Stuck pixels can glow in different colors: red, yellow, blue, green. The reason for this is the on or off state of the subpixels.
Most users might think that if such a problem arose, it could be solved by sending the device for repair or exchanging the device under warranty. However, panel manufacturing technology is very complex, making it nearly impossible to produce large production runs of LCD panels without dead pixels. Even if only “clean” panels were used in production, the price of TVs would be high.
To solve this problem on Apple devices, there is a program that solves it - Bad Pixel Fixer. This program can be free and easily installed from Cydia.
You need to do the following:
- First, you need to make sure you have an Internet connection and then go to Cydia.
- Type - Bad Pixel Fixer in the search.
- Then make sure that this program from the repository is BigBoss.
- Next you need to install Bad Pixel Fixer.
- After the installation of the program is completed, you will see the “Bad Pixel” icon of this program in the menu of your device.
- Then run the program.
- Here you need to select a background - black or white. In the background, you can identify a dead pixel and find out which group it belongs to.
- Point the square at the place where you found the dead pixel.
- Set the maximum interval, and select the color of the square in accordance with the color dead pixel, then all the colors of this square and click Start.
The work will take about 40 minutes. First you need to set the square with the dead pixel color. If this doesn't work for you, set all the colors of the square. We wish you good luck!
