- currently Server and Android use https for communication
- Server integrates Symantec"s certificate
- Android integrates certificates of intermediate CA
due to the current problem, there is a problem with the intermediate CA, and the server applies for a certificate under the new ca and replaces it.
but this situation requires android to update the trusted ca certificate, but our android device update is out of control.
I would like to ask that there is no other way to update ca certificates except app updates
and the ca certificate also has a validity period. When the validity period expires, how does the general android update the certificate?
