Before, the software was installed on the mobile phone, and then only the software itself was uninstalled when it was uninstalled, but the residues such as signature files were not removed. When installing the software again, the signature conflict cannot be installed.

In this case, you can consider downloading a lower version to achieve the purpose of compatibility with mobile phones. Generally, the introduction of the application download place will write down the minimum requirements for the mobile phone system version before installation.
