How to View Trusted Root Certificates on an Android Device
Tap “Security & location”
Tap “Encryption & credentials”
Tap “Trusted credentials.” This will display a list of all trusted certs on the device.
those are all verified......not sure what you are asking. there is no way to manufacture those. they are saved on the system partition of your phone. you do not have access to alter those unless your phone is rooted.
Well... let me put it this way since I don't work with you guys lol. Which ones of all the ones installed, specifically the ones NOT FACTORY INSTALLED because there's so many jumping in with AUTHORITY can be safely removed for whatever reason. ?
