What do you do when your phone’s screen suddenly turns black and white. There are many ways to quickly fix this situation that you can do at home without having to take it to a repair shop!

Causes of phone screen turning black and white

Multiple running background apps

When there are too many apps running simultaneously, the phone’s operating system and hardware components such as RAM and processor have to handle multiple tasks at the same time, leading to overload.

Once the system is overloaded, the phone may experience issues such as lagging screen, slow response, or even the screen turning black and white.

Phone overheating

If your phone gets too hot, it can cause the screen to turn black and white. When you use your phone to play games or use multiple apps at the same time, it consumes a lot of resources and operates continuously, causing the phone’s temperature to rise.

Startup failure

If the phone screen turns black and white immediately after startup, it may be due to a system failure. In some cases, the smartphone’s operating system may encounter issues when loading the necessary components to display complete colors on the screen, resulting in only black and white display.

Using the phone while charging

Using the phone while charging can cause the phone to turn black and white because the current becomes unstable, and there is also the potential for battery damage and explosions.

Enabling black and white mode

On some mobile phones, there is a mode called “Black and White mode” or “Negative color mode” in the display settings. When this mode is enabled, the screen will display images and colors in inverted form, making everything on the screen appear black and white.

Faulty LCD screen

This is also a reason why the phone screen turns black and white. This is a hardware failure.

Dropped phone

Avoid dropping or hitting the phone as it increases the risk of screen damage or the screen turning black and white.

Faulty color sensor on the screen

The color sensor on Oppo phones is responsible for recognizing and adjusting color parameters on the screen. If the color sensor on the Oppo phone is damaged, it can cause the phone’s screen to turn black and white or display colors inaccurately.

How to fix phone screen turning black and white

If your phone unfortunately turns black and white, is the solution complex? In fact, you can apply the following solutions before taking it to a repair shop:

Turn off power-saving mode

Turning off power-saving mode is also one of the ways to fix phone screen turning black and white. Power-saving mode often limits the operation of apps and features on the phone to save power. This can cause some limitations in screen display and operation.

To turn off power-saving mode on your phone, you can follow these steps (the steps may vary depending on the operating system version and user interface):

Step 1: Open the Settings app on your phone.

Step 2: Find and select the Battery or Power section. Find the option for Power-saving mode or Battery saver and turn it off by selecting the off option or sliding the status button to the off position.

Restart the phone

Restarting the device is a common and simple solution to fix the phone’s black and white screen issue. By turning off and restarting, the phone will perform the process of restarting the operating system and apps, which can solve the problem you are experiencing and restore the screen to normal operation.

Turn off black and white mode

You can easily turn off black and white mode on your phone by selecting “Accessibility and control options” and pressing “Relax”. If after performing this operation the phone is still in black and white screen mode, swipe the screen to open the status bar. Tap on the menu icon, accurately determine the location to tap on the Gray Scale icon. Turn off this mode when the icon is bright.

Clear cache

Clearing the cache of apps is a way to free up memory space and can help improve the performance of apps on the phone. Below are the steps to clear the app cache on your phone:

Step 1: Open the “Settings” app on your phone.
Step 2: Find and select the “Apps” or “App Management” section. In this section, you will see a list of apps installed on your phone. Find and select the apps you want to clear the cache for.
Step 3: Select “Clear cache” or select “Clear app cache” depending on the phone model. Repeat the process for other apps you want to clear the cache for.

Uninstall unnecessary apps

Uninstalling unnecessary apps is a good way to free up storage space and improve the performance of your phone. Using too many apps will slow down the phone, consume storage space, and make it prone to damage and lag.

Factory reset

This is an effective solution to fix issues related to black and white phone screens or other issues. However, the process of factory resetting the phone will restore the device to its default state and delete all data, settings, and apps on the phone. Therefore, it is essential to back up important data before performing this action.

Update to the latest version

If the phone screen turns black and white is difficult to resolve, you need to update your phone to the latest version. Go to “Settings”, select “System update” to fix the screen issue.

Take it to a repair shop

If after trying the above solutions, the phone screen still turns black and white, you should take the phone to a repair center or shop. Trusted centers will have professional technicians with the knowledge and skills to handle complex technical issues on your phone.
