1, restart the phone: Sometimes, restarting the phone can solve the problem of signature conflict. After the restart, the mobile phone system will be re-certified to solve the installation problem caused by signature conflict.
2. Clear the application cache: enter the settings menu of the mobile phone, find the application management (also called application management or application and notification), select the related application, and click Clear the cache. This will clear the application's cached data and resolve the signature conflict.
3. Reinstall the application: uninstall the related application, download and reinstall it. Pay attention to check the signature information of the application during the installation process to ensure that it is consistent with the signature authentication of the mobile phone system. The application's signature does not match the system, which will lead to signature conflict.
