The good is long overdue. Almost a year ago, they discovered in the APK of the Google app that two new features were yet to come: homework mode and offline translation. Education mode finally arrived in August and is now starting to activate translation without internet connection.
The translator built into Google Lens now works the same as the Google translator: it can be used without an internet connection, as long as you have language pack downloaded before
Offline translation in Lens
Over time, Google Lens has become much more than an application for searching for objects with the camera on the Internet, but has become a comprehensive tool. The same helps you in the tasks that serve as a bridge between the mobile and the PC, identify the breed of a dog or serve to translate texts. Of course, as long as you have an internet connection.
Although Google Translator has been integrating offline translation for many years, it was not present in Google Lens until now when the download language packs. The system works the same as in Google Translate: you download a language pack of just under 100MB and you can then translate between the languages you downloaded, without having to be logged in.
This new feature was spotted in Google Lens in March 2020, although so far when it finally started showing to users it hasn’t. To download a language pack in Google Lens, you must tap on the bar where the languages are indicated
The novelty is that while previously there was simply a list of languages to choose from, now there is a download button next to each language. You must download the package of the two languages you are going to translate between to be able to do the translation without an Internet connection.
