Hey @FlawlessSpa!
Our sincere apologies for the delays on this. It took us some time to get you a response as we had to reach out to LG directly as well as our product team.
On the LG end, here's what they mentioned:
- All Android devices(LG electronics and other all OEM) contain Root CAs by AOSP(Android Open Source Project).
- AOSP refers to a Mozzilla CA certificate store when OS released.
- OEM cannot add/delete/modify those CAs because Google restricts those lists.
To simplify things, all Android phones and tablets (not just LG ones) contain certificate authorities (CAs) that the manufacturers of the devices (such as LG) cannot modify or delete. These ones are installed on your tablet and cannot be changed.
To go a little further, our product management team mentions that the preloaded trusted certificates on Android devices are part of the system root store. These are used to determine if a certificate issued by a particular Certificate Authority (CA) is trusted. They are only managed by Google. If and when there are any "user" specific trusted certificates needed they can be installed however LG does not install any in the tablet.
I hope this sheds some light! Let us know if you have other questions
