I justed tested this exact code in the RNTester example and I could not reproduce on Android API 30. Please include details of the Android API on which you experience this issue and the rn version.

I have been testing on the latest react-native master. Thanks

Since this does repro in Expo, is the problem that Expo is lagging behind on Android SDK maybe?

[luanccp]

Any news here? Facing the same error.

It is also appear on Android version 10 (real device Samsung A7). React native version 0.64.2

Previously, the TextInput shows: "This is a tex...". But now, the placeholder has multiple lines, which break the App's UI
