Description
Description
If the phone has the RTL (Hebrew) language installed, then the Text component behaves incomprehensibly. The child element moves to the left. This bug does not occur on all devices. In the emulator, Galaxy Tab S6, web or in expo go, everything is displayed well. I noticed this bug on the Galaxy A9. If you change the system language to LTR, then everything is fine and the shift disappears.
React components should be able to be placed anywhere in the application. In my case, I wanted to place a View in a Link from @react-navigation/native and noticed this bug. But this only applies to View component
my code:
import React from 'react';
import {SafeAreaView, Text, View} from 'react-native';
function App(): React.JSX.Element {
return (
<SafeAreaView>
<View
style={{
backgroundColor: 'black',
paddingVertical: 10,
paddingHorizontal: 50,
}}>
<Text style={{backgroundColor: 'red', paddingVertical: 5}}>
<View
style={{
backgroundColor: 'yellow',
paddingVertical: 5,
width: '100%',
}}>
<Text style={{backgroundColor: 'green'}}>
{'\u05E9\u05DC\u05D5\u05DD'}
</Text>
</View>
</Text>
</View>
</SafeAreaView>
);
}
export default App;
Steps to reproduce
- Set language on mobile device Hebrew
- Install app to device
- Look at the block offset

This is what I got as a result:
Expected behavior: the child element must fit within the Text horizontally.

Research direction
Start with the linked reproducer and the provided nested Text/View example on an Android device using Hebrew RTL, especially the Galaxy A9 case. Compare the child View placement with LTR and other environments, then trace the Android Text layout behavior; done means the child remains within the Text horizontally under the reported RTL conditions.
