Installing a certificate

Maybe if you have an organisation-managed headset using Meta Managed Services?

I just want to note that many if not all of Metas build in apps use certificate pinning.

I found this stackoverflow answer helpful. This assumes your device is in developer mode. Connect to it via adb and run this command to start the traditional android settings app.

./adb shell am start -n com.android.settings/.Settings\$NetworkDashboardActivity

Then scroll down to security and privacy.

At the bottom of this menu there is "More Security Privacy"

Then there is an entry called Encryption and credentials

under this menu there is an option to add certificates from your local storage.

I have not attempted the last step myself but i hope that that works for you.
