Hello, I'm trying to encrypt the internal storage of my Galaxy S9 Plus, uses VZW. In settings the only option is to encrypt an SD Card. I've contacted Samsung Support, they were useless bounced me around from department to department until i got disconnected. My company uses AiWatch for corparate email on mobile devices, they recommended a Samsung phone because it has Knox, or an iPhone. In order for my device to be compliant it needs to be encrypted.
