Oppo weather forecast shows why it is gray.

The brand's mobile phone weather forecast is grayed out for the following reasons:

1. Version problem: The weather forecast application may not have a color interface, so you can try to upgrade to the latest version.

2. Theme Settings: If black-and-white themes or other similar themes are enabled, the weather forecast application may be displayed in black-and-white or grayscale mode instead of color mode, so you can try to change the theme settings.

3. Device compatibility: Some mobile phone models may not support the color weather forecast interface, which is related to the hardware specifications and software compatibility of the device.
