Affected version

0.28.1

Steps to reproduce the bug

  1. Add multiple languages to Android System (for example English (US) as primary and Japanese as secondary)
  2. Open NewPipe and see some UI texts are in mixed languages

Expected behavior

It should show UI Elements in the primary language set in Android System

Actual behavior

UI Elements are shown in mixed language

(Mainly English and a bit of Japanese, but sometimes almost every UI element is in Japanese, it's random)

This bug occurs with other apps but it can be resolved by adding another variation of English as secondary language and putting Japanese as third (example: 1. English (US) 2. English (UK) 3. Japanese)

Research direction
Investigate the Android system's locale resolution when multiple languages are set. Check NewPipe's res/ directory for string resources and any custom locale handling code. Reproduce the issue with different language orders. Look into how the app loads localized strings, possibly in the Application class or Activity. Consider if the issue is related to resource qualifiers like lang+region vs lang. Test with English (US) primary and Japanese secondary, and try swapping orders. Suggested files: res/values/strings.xml, res/values ja/strings.xml, and any locale related code in the app.
