Why didn't K30S U update MIUI 13 to protect the privacy of the front camera?

After K30S U updated MIUI 13, the privacy protection of the front camera strengthened the function of the front camera, which not only protected privacy, but also prevented social death.

Because Xiaomi is an Internet company that needs rapid iteration, there are many cases of security and privacy vulnerabilities after the device or service goes online.

More than 90% of the vulnerabilities are discovered by technicians at an early stage, so it rarely has a huge impact on users.
