yeah, i have the same issue in miui 12 but it is fine in miui 10 and 9. Not sure it's a issue in react-native or miui.
My rn version is 0.59.9.

The phone number and the word 'message' disappeared.

currently ,we hook Text render to make it work correctly.
`
const originTextRender = Text.render;

Text.render = function render(props, ref) {

    return originTextRender.apply(this, [{ ...props,  style: [isMiUi12() ? {fontFamily:''} : null, props.style] }, ref]);  

};

`

This is caused by the default FontFamily of MIUI 12: "小米兰亭 PRO". It's a variable opentype Font, look like react-native doesn't support it.

It did work to set a default property - {fontFamily: ''} in style property of Text

What is your code to detect MIUI12 in isMiUi12?

the code likes below

import {  Platform, NativeModules } from 'react-native';

function isMiUi12() {
    if(Platform.OS === 'android' && NativeModules.PlatformConstants){
        const fingerprint = NativeModules.PlatformConstants.Fingerprint && NativeModules.PlatformConstants.Fingerprint.toLowerCase();

        // MiUi12 fingerprint:Xiaomi/cmi/cmi:10/QKQ1.191117.002/V12.0.1.0.QJACNXM:user/release-keys
        if(fingerprint && fingerprint.startsWith('xiaomi') && fingerprint.indexOf('v12')!==-1){
            return true;
        }
    }

    return false;
}

any update ?

MIUI 12.0.5 , same here

This looks more like a MIUI 12 issue to me.

We had the same problem, but when we changed the system's font weight to another value (in Settings - Display - Text size & font weight), the issue disappeared. When we changed it back to the original value, the rendering remained perfect.
