According to your description, due to the possibility of compatibility of third-party software, the incoming call cannot be unlocked normally. I suggest you uninstall the snack table first, and then observe the use to see if the situation has improved.

If necessary, you can also try to search and download from Lenovo Music Store to replace other third-party desktops (such as go desktops).

Go desktop download address: /appstore/html/search.html? skey = go % E6 % a 1% 8C % E9 % 9D % A2
