Many users of the ChatGPT Android app are experiencing an issue where the Enter key has changed to a send button, making it difficult to compose multiline prompts. Complaints have increased, with users expressing frustration over the inability to create separate paragraphs. Discussions on platforms like Reddit indicate widespread dissatisfaction, with some users tagging OpenAI for clarification. Not all Android users are affected, suggesting the possibility of A/B testing or a keyboard-specific glitch. Users who switched from Microsoft SwiftKey to Gboard reported a resolution, while some Samsung keyboard users also faced similar issues. The recommended solution is to install Gboard and set it as the default keyboard. OpenAI has not publicly acknowledged the issue, and a fix is expected to be implemented quietly.
