Core concept

@ohos.deviceInfo (Equipment information) This module provides terminal device information query, which cannot be configured by developers. Note: This module interface returns device constant information. It is recommended that the application only calls it once and does not need to call it frequently.

Import module:

import { deviceInfo } from '@kit.BasicServicesKit';

Practical code

import { deviceInfo } from '@kit.BasicServicesKit';
