Why can't Apple's mobile phone download healthy Gansu?

Apple phones can't download Healthy Gansu for the following reasons:

1, the phone is out of memory. When the memory of the mobile phone is insufficient, it will affect the normal installation of the software. If you are prompted that the phone memory is insufficient during the installation process, it is recommended to uninstall the unused phone APP and clean up the phone memory.

2. The download source is unknown. Sometimes the APP that may be downloaded can't be searched in the application market that comes with the mobile phone, so we have to download and install it from other channels. During the installation process, you will be prompted to prohibit the installation of software from unknown sources.

3. The application installation package is damaged. Sometimes the software can't be installed, and the mobile phone will prompt "the application is damaged". This may be because there is a problem in downloading or parsing the installation package, so you can choose to download the installation package again.

4. The mobile phone system version does not match. Sometimes you will be prompted when downloading and installing the software because the system version is too low to use.
