1. Browser history is cleared: If you choose to clear the history when using the browser, or use the cleaning software to clear the phone cache, the browser startup history will also be cleared.

2. Browser settings: Sometimes browser settings may affect the display of startup records. You can try to find relevant options in the browser settings, such as "History" and "Privacy Settings" to see if any relevant settings are disabled or turned off.

3. Browser version problem: If your browser version is too old or there are some problems, the startup record may not be displayed normally. You can try to update your browser or replace it with another browser.
