What if I can't install the updated software on my Android phone?

The application downloaded by Android phone cannot be installed. The treatment method is as follows:

First, it may be caused by a file error during the download process, so it is recommended to download and install again;

Second, if it still can't be installed, please check whether the mobile phone space is sufficient;

Third, check whether "unknown source" is turned on;

4. Other software has minimum requirements for system version. Please check whether the mobile phone system supports it.
