The latest Android operating systems introduce convenient features like Chat Preview, Reply Button, and Smart Replies, aiming to streamline communication. However, some users, like those on an Oppo F21s Pro running Android 14, are encountering difficulties with these functions.

While the intended functionality of these features is clear - enabling quick responses without fully opening an app - the frustration stems from their inconsistent behavior. This guide aims to shed light on this issue, help troubleshoot potential problems, and explore potential solutions.

Stepping into the specifics, your description indicates that despite enabling these features, you're not seeing them in action. To pinpoint the cause, it would be helpful to delve deeper:

* **Method of Activation:** Did you enable the features through the system settings or within specific apps? Different apps might have their own configurations.
* **App Compatibility:** Not all apps necessarily support these features. Try testing with different messaging applications to see if the issue persists.
* **Recent Changes:** Have you made any recent changes to your phone's settings or installed any new apps? Sometimes, conflicts can arise after updates or installations.
* **Fresh Installation:** As a last resort, consider restarting your device or even a factory reset, while ensuring data backup, to rule out software glitches.

Remember, providing more detailed information about the specific error messages you encounter, if any, would be invaluable in further troubleshooting. The Oppo F21s Pro community might offer insights or workarounds based on your device model too.
