Adds File Scan, version one of the scan engine that is set to replace Hypatia inside DresOS. It checks any file or every installed app by fingerprint, so nothing is ever uploaded, only a SHA-256 that comes back checked against seventy or more engines. Adds Spam Shield, which screens calls on the device before your phone rings, blocks premium rate numbers, flags callers faking your local prefix, and lets you block or unblock any number from the call log. Encryption keys are now per contact instead of one code shared with everyone, and old messages still open. The screen now turns off against your ear during calls. New messages suggest your contacts as you type, and the option to save a number is hidden once it is already saved.
