#196851 - Markdown editor doubling words on GitHub Android

This is a known bug in the GitHub Android app markdown editor. When you press Enter (or the return key on your keyboard), the last word of the current line gets duplicated on the new line.

Workarounds

1. Use the web editor instead: Open github.com in your mobile browser and edit there. The web-based markdown editor does not have this issue.

2. Disable autocorrect/predictive text: In your Android keyboard settings, turn off predictive text and autocorrect. This bug is triggered by the interaction between the GitHub markdown editor and Android input method editors (IMEs).

3. Use a third-party git client: Apps like Pocket Git or MGit let you edit files without hitting this bug.

4. Type in a separate editor first: Compose your markdown in a notes app, then paste it into GitHub.

Reporting the bug

If you have not already, please report this through the official channel:

• Open the GitHub Android app > Settings > Report a Bug
• Or file an issue at github.com/github/android/issues

Include your Android version, device model, keyboard app (Gboard, Samsung Keyboard, etc.), and GitHub app version. This information helps reproduce the bug.

The bug appears to be in the markdown editor text input handling — specifically how the app processes IME composition events when the Enter key is pressed. It is most noticeable with CJK keyboards and predictive text enabled.
