On-Device Translation
One of the bigger new features in iOS 14 is a new translation app, and while Apple is far from the first to offer translation services, it differs in that its own translation app will be capable of performing all of its operations directly on your iPhone, without relying on cloud servers.
While Apple has long done this by default with things like photo processing, it’s a bit different with Translate, however, as you’ll need to go into settings and enable “On-device mode” if you don’t want your translations handled by cloud services, with Apple noting that “on-device translations may not be as accurate as online translations.”
