What should I do if color stripes appear on the screen of my Huawei phone?

It is recommended to use the phone screenshot feature to take a screenshot of the current interface.

1.When the abnormal line moves with the picture.

1) It is recommended that you restart your mobile phone to try, if the phenomenon is still there, it may be the system, software application design, please feel free to use.

2) If you have turned on Developer Options or Developer Options, and turned on Pointer Position, the screen will display the current touch data, the screen will appear fluorescent traces where your finger is swiped, and a blue cross will appear where your finger touches the screen.

2.When the abnormal line does not move with the picture.

Color stripes, vertical lines, lines, etc. are all manifestations of the blurred screen: the cable is broken, the screen is broken, or the motherboard is broken.

If the cable is broken, the cable connecting the screen and the motherboard is burned or loosened, so it's good to change the cable.

The screen is broken, and the LCD screen is broken, this kind of no way, the most troublesome, to replace the entire screen assembly, the cost is high.

If the motherboard is broken, it is also to replace the entire motherboard, but this probability is relatively small, but it is not ruled out, the way is to replace the motherboard, and the motherboard is generally cheaper than the screen.

When there are a lot of colored vertical lines on the mobile phone screen, it is because there are too many dead pixels on the screen, which is very serious, and even leakage will cause this, this kind of screen cannot be repaired, and only one display screen can be replaced, so I judge that your Huawei mobile phone must replace the display.

Perform the following steps:

a. If there are scratches on the protective film, it may be that the protective film has been scratched with small scratches into the water vapor, and there is a phenomenon of colored line copying strips under the light, it is recommended that you tear off the protective film to eliminate the influence of the protective film.

b. If only part of the scene is visible, it is recommended to change the background pattern, which may be that the background pattern makes users mistakenly think that Bai is a line.

c. The mobile phone turns on the pointer position, and the screen will display the current touch data after the pointer position is turned on, and the screen will have a fluorescent track where the finger crosses, and the blue cross line will appear at the position where the finger touches the screen, which is normal. Set the path:

Settings > About Phone", then tap the version number 7 times in a row (if you set a lock screen password, you will need to enter the lock screen password) until the screen prompts "You are in developer mode!" Go back to Settings and click Developer Options > Pointer Position" to turn it off.

and go up: "Settings > System > About Phone", and then tap the version number 7 times in a row (if you set a lock screen password, you need to enter the lock screen password) until the screen DAO prompts "You are in developer mode!" Go back to "System" and click Developer Options > pointer position, and turn it off.

If the problem persists, it can be judged to be a faulty screen, so we recommend that you back up your data in advance and repair it at a nearby Huawei Customer Service Center.

If it's a hardware problem, in fact, there is not much you can do, and the official after-sales channel is the first choice for maintenance and replacement; However, if your mobile phone has exceeded the warranty period, or even disassembled it yourself, then you can also consider repairing it yourself.

Cable: After dismantling, check whether the mobile phone cable has fallen off and loosened, if it is determined that it has burned out, you can buy parts from a treasure to replace.

Screen: Now most of the screens use full lamination technology, and if the inner screen is damaged, the screen must be replaced, and the maintenance cost is higher.

Motherboard: This doesn't seem to be a good way except for official or professional maintenance, but ** it will generally be cheaper than changing the screen.

If it is determined that it is a software problem, Android can be flashed, Apple can be downgraded, and if the wallpaper is affected, you can change the wallpaper and restart. However, with the continuous improvement of mobile phone technology, the mobile phone screen has become less and less colored, if your mobile phone has been in service for a long time, direct replacement should be the simplest and most crude way.
