Codes
import React from "react";
import { Text, View } from "react-native";
import { Header } from "react-native/Libraries/NewAppScreen";
function App(): JSX.Element {
return (
<View>
<Header />
<Text style={{
fontSize: 16,
backgroundColor: "red",
marginTop: 200,
alignSelf: "center",
textAlign: 'center',
fontFamily: "BarlowCondensed-Regular"
}}>
番号を変更
</Text>
</View>
);
}
export default App;
Screenshot
Actual behaviour
The text does not align center and the content shows incomplete. It seems that it's cut off and moves down!
Expected behaviour
The text aligns center and the content shows complete. For example:
However, if I sets lineHeight: 20 like
<Text style={{
fontSize: 16,
backgroundColor: "red",
marginTop: 200,
alignSelf: "center",
textAlign: 'center',
fontFamily: "BarlowCondensed-Regular",
lineHeight: 20, // here!
}}>
番号を変更
</Text>
Everything works well on all devices! But I think we shouldn't always set lineHeight to avoid this problem. It should be a bug on Android. Any ideas or how to fix it using a efficient way?
At last, the font file(BarlowCondensed-Regular) can be downloaded via the link: BarlowCondensed-Regular.
Any help will be appreciated.

Research direction
Start by reproducing the issue from App.tsx with the font in android/app/src/main/assets/fonts on an affected Android device such as the OPPO K9x 5G. Compare the Japanese Text rendering with and without lineHeight: the work is complete when the content is fully visible and centered without requiring lineHeight.
