If the password verification page does not display completely when changing the app lock to the 16-digit privacy password on the Xiaomi 17 Ultra, please refer to the following steps to troubleshoot:
1. The issue can be caused by an outdated version of the Security App. Please update the App to the latest version.
2. A temporary display adaptation glitch can affect the page layout. Please restart your phone and try again.
3. Excess cached data in the Security App can cause abnormal display. Please clear the app cache and reattempt the operation.
4. An outdated system version can affect compatibility with the 16-digit privacy password function. Please check for system updates and upgrade to the latest version.
5. If the issue persists after completing the above steps, please contact the after-sales service center for further assistance.
