What's going on with Huawei phones turning into black and white screens.

1. It may be that the analog color space switch is turned on;

2. If there is a bug in the mobile phone system, it is recommended to update the system or shut down and restart;

3. The mobile phone is installed with third-party software similar to the theme of the mobile phone or the adjustment of the screen brightness, it is recommended to uninstall it.

1. Please press and hold the power button and the home button at the same time, and when it lasts until the 10th second, please release the switch button immediately, and continue to hold the home button. 2. At this time, iTunes will automatically start and prompt for recovery mode, then you can hold down the shift key on the keyboard, click "Restore", and select the corresponding firmware for recovery. 3. Find out the results.

Then select the downgraded firmware, which one you want to downgrade. 4. Select one key to flash the machine, enter DFU mode, and wait for the downgrade to be successful. Flashing Risk:

When it comes to risk, there is a certain amount of risk with all flashes, and the key is whether you can minimize or even remove the risk. First of all, it is certain that the normal flashing operation will not damage the hardware of the phone. Secondly, flashing can solve some inexplicable problems of the mobile phone, upgrade the hardware driver of the mobile phone (just like upgrading the BIOS of the computer), and add countless DIY functions to the mobile phone.

However, improper flashing methods may bring unnecessary troubles, such as failure to turn on, crash at startup, function failure and other consequences.

You have the e-book mode turned on, just switch back to it in the status bar.

Maybe you set it yourself, or maybe you turned on the power saving mode. Or it's a problem with your phone's theme.
