What s the deal with the fact that the phone always flashes so hard in low light?

It may be that there is a problem with the light sensor that senses the outside world, or there may be a problem with the screen cable.

I think there is a point to explain: you go to change the inner screen of the mobile phone, the maintenance point should be replaced with a new screen in good condition instead of a screen without reflective paper, the reflective paper is damaged by the maintenance personnel, not by your owner, so the maintenance personnel should bear this responsibility, it stands to reason that you should re-replace a good new screen, as for the screen with less reflective paper, the maintenance staff will find a way to solve it, and it has nothing to do with your customers.

Besides, the screen has a horizontal bar scrolling from top to bottom,It depends on whether this phenomenon is obvious,If it is obvious,You can see it at a glance,It may be a problem with the screen itself (the screen itself is a problem here,It has nothing to do with reflective paper),If the phenomenon is not obvious,Only from a small angle can be seen,There may be no problem with reflective paper。

Other than that, the chances of the motherboard causing this phenomenon are slim. (The early kind of black and white screen can see this situation from a small angle, which is determined by the display characteristics of the screen itself, I think yours must be an LCD color screen). On the whole,I think you still have to find someone at the maintenance point,If he says it's not a problem with reflective paper,Then let him find out the cause of this phenomenon,After all, there was no such phenomenon before the screen was broken,Only after changing the screen。

In short, it's a problem that only occurs when the screen is replaced, and it's not that the repairman broke it, first let him find out the reason. I think the problem is with the screen.

Screen light leakage is caused by the screen and backplane bezel packaging is not tight, fault or aging caused by the screen edge of the light, and the LCD panel appears local whitening on a solid color background.

The effects of light leakage on mobile phones are as follows:

1. Affect the visual effect when watching the movie.

2. When the mobile phone screen is displayed in full black, the part that leaks light is displayed white.

It is understood that there are several types of light leakage, including compression light leakage, BL light leakage, etc.

Compression leakage is colored, not a white one. It usually appears on the upper and lower sides, and rarely on both sides. The oppression leakage is either caused by the screw lock being too tight or the screen frame is too tight, and we can't fix it.

Whether there are bright spots, dark spots, and black dots on the screen. It's all specified.

BL leaks are white. BL light leakage is generally patted vigorously by hand will have a noticeable effect.

In fact, the screen light leakage is caused by the fact that the LCD panel does not fit closely with its frame, and the light emitted by the backlight is transmitted to produce light leakage, which is a common problem for all devices using liquid crystal display technology, and it is almost inevitable. Therefore, no manufacturer will replace it. Another case is the system.

If there is a malfunction, you restart the phone, if it still can't solve the problem, you can only understand the detection through after-sales.

What's wrong with the phone flashing white all the time? It may be that your phone has set that sensing community or the lights are flashing all the time, time, screen display time, standby time.

Summary. This situation may be caused by voltage fluctuations caused by damage or aging of the mobile phone battery, and there may be a problem with the hardware of the mobile phone, so it is recommended to go to the mobile phone repair shop in time to check and replace it.

I'm still a little confused, can you be more detailed?

1.It may be that the mobile phone battery is insufficient: when the mobile phone is low on power, the mobile phone screen will flicker due to insufficient system power supply; 2.

It may be that the internal temperature of the phone is too high: when the internal temperature of the mobile phone is too high, the circuit board of the mobile phone will have thermal sensitivity problems, which will cause the screen to flicker; 3.It may be that the contact at the interface of the mobile phone is poor:

When the interface of the device is not in good contact, voltage fluctuations may occur, which will cause the mobile phone screen to flicker; 4.It may be that the phone screen is malfunctioning: when the phone screen is malfunctioning, the screen will flicker due to damage to the internal circuit of the screen.

Summary. 1: Disable the screen update. Android or above, then you can try: Settings - > Developer Options (or Developer Options), and uncheck the "Display screen update" checkbox.

1: Disable the screen update. Android or above, then you can try: Settings - > Developer Options (or Developer Options), and uncheck the "Display screen update" checkbox.

Solution 2: Adjust the screen brightness setting settings -> display -> automatic brightness adjustment, turn off this function and try it. Workaround 3:

If that doesn't work, try a factory reset. If it's still not good, then it's a hardware problem, and you can only take it to a repair shop or after-sales point to deal with it.

Give it a try. Good.

The hardware problem is that.

It's right next to the motherboard.

Is there a problem with the motherboard cables?

No. Is it the motherboard hardware, virtual soldering?

If you have a mobile phone, you only have one piece of hardware.

Is there a problem with the motherboard?

Right. Is it a virtual weld if you fall?

What does virtual soldering mean.

To put it simply, it's a motherboard problem.

Reason: Hello, if the Android phone screen keeps flashing, in fact, this is a common phone screen failure. Some are due to settings, and some are due to issues with the quality of the screen. Workaround:

1: Disable the screen update.

If the phone system is Android or above, then you can try: Settings -> Developer Options, which will "Show Screen More."

New" is unchecked.

2: Adjust the screen brightness settings.

Settings -> Display -> Auto Brightness Adjustment, turn off this function to try. 3: If these two methods still don't work, try a factory reset.

If the above methods still don't work, then it is recommended to go to the mobile phone after-sales service or find a professional mobile phone repairer to check it to see if it is a hardware problem.

Because you are not replacing the original screen, the screen of the mobile phone is damaged again due to quality problems or some other factors after installation.

If you don't check this situation, no one will know the problem at once. If it's time to test, don't be afraid to spend money, who let the phone go wrong? No problem, I won't check it out.

If you just say that, people don't see the machine, just like a doctor can't see a patient and can't see it, so he can prescribe you a prescription casually? If someone says that you just need to replace a part if it is broken, can you replace it yourself? Do you have to find a professional?

What you can't solve by yourself should be done by others, so you can do it for others. Earning money is all about enjoyment. Spending money is on services.

The same is true of the areas you are familiar with, and others can't solve anything without spending money.

It may be that the internal motherboard is broken, so you can change the motherboard and buy a motherboard yourself.

The phone is flashing the screen, but what is the matter if the screen is not flashing in the dark.

Kiss. 1. Before cleaning the induction hole and the mobile phone has a flickering screen failure, if the screen of the mobile phone has been pasted with a film, then it is almost certain that the mobile phone film causes the first mountain fault of the mobile phone to have a flickering screen. You must know that the mobile phone itself is equipped with an infrared sensing device, when answering **, the mobile phone is close to the ear, and the screen of the mobile phone will automatically go off, which is the role of the infrared sensor.

If the phone membrane interferes with the function of the sensor, then the phone will have a splash screen. When encountering this kind of problem, the easiest and most direct way is to remove the phone film, and the phone will return to normal. 2. In addition to the problem of infrared sensor hole, there is another common situation of uninstalling software, that is, the splash screen caused by software conflicts.

If some unknown software is installed before the mobile phone has such a failure, these software may conflict with the mobile phone's system and protection software, and it will also cause the mobile phone to have a flickering screen. Taking Android phones as an example, because there are more permissions for software, some software violates the rules to access sensitive functions, which will be recognized by the protection software, or conflict with other software, which will cause the screen of the mobile phone to switch frequently. In this case, turn off the phone first, then turn it on, uninstall the software you just installed, and the phone will return to normal.

3. Disassembly and repairIf the mobile phone has been injured or in a state of high-frequency vibration before the flickering screen problem, then the cause of the mobile phone flickering screen may be caused by problems with the front panel and backplane wiring of the mobile phone. If the phone's outer glass and touchscreen aren't shattered, it's almost certain that there's something wrong with the bottom two screens, most commonly loose cables. In this case, the individual is unable to repair, the easiest way is to find after-sales help to detect, and then disassemble the machine for maintenance.

Digression: In addition to the above three faults, the mobile phone settings automatically identify brightness, voltage instability, and strong magnetic interference, and the mobile phone screen will also appear flickering, but this flickering screen is not obvious, but it is intermittent, and it can be restored to normal by changing the use environment.
