I'm sorry for the inconvenience.

If your device cannot install all the software, please check it according to the following methods:

1. Confirm the option of opening unknown source: System Settings-Security, select unknown source and check it;

2. Enter the system settings-check whether the storage space of the mobile phone is insufficient. If it is not enough, you need to uninstall the old application to release space;

3. If it is not caused by insufficient storage space, it is recommended to restart the mobile phone and try to rule out whether it is caused by temporary system abnormality;

4. Check whether the software installation package is completely downloaded or defective. It is recommended to download in a stable wifi environment and go to Lenovo Music Store (/servicestation.aspx;
