Take Huawei P40 as an example. Under the EMUI 1 1 system, you only need to turn on the mobile phone, bring up the mobile phone keyboard, click the symbol option on the keyboard, find the special symbol after opening it, and then you can see the five-pointed star symbol, both hollow and solid, and select the click you need.
Tips for using mobile phone: Huawei P40 supports dark mode. If the user likes it, just turn on the phone, pull down to the control center page, find the dark mode button in the shortcut function and click it to open it.
