I realize sometimes when browsing with HTTPS, it shows the certificate is not valid, "This certificate is not from a trusted authority". Clicking "continue" will just pop up the same warning. That time, I start thinking the certificate store is not updated. I try to compare with Windows trusted CA which will be updated automatically.

I think the certificate must be updated in a period of time since the validity of trusted CA is about 1 to a few years.

I cannot find this thing mention in Android anywhere. Does the way it manages certificates is different? How can I make sure I get the latest update?

Many years later, this will finally be addressed. Android 14 will update the trust store via Google Play Store. Earlier versions required the device manufacturer to push an over-the-air update with new certificates, which wasn't always provided quickly or at all for older devices.
