Vietnamese language missing

In the “QField Settings” page - “General” tab, you can specify the language you want to use in QField.

Vietnamese is missing, and we would like to get it there for a local project. Is anybody aware of a list of steps/conditions that need to be taken/fulfilled?

Is it a question of adding the option somewhere in the code of QField? Or does the language need a minimum translation % on the Transifex platform?

We’re very grateful for any knowledge or experience that can be shared.

Thanks a lot in advance, QField Community!

(there was this very similar issue from 2025: QField 2.x Czech UI language missing - Ask the Community - QField community, but no relevant information was added)

@Ward , the minimum percentage translated is 50% (QField/scripts/ci/pull_translations.sh at baa933385187dfe9d78dd9b73cea21a61cba4a1a · opengisch/QField · GitHub).

As we speak, the Vietnamese language has 19.1% translated. If you know people who can help to get up pass threshold, that’d be fantastic.

@Mathieu_Pellerin , thank you for taking the time to answer! That 50% is a clear goal :slight_smile: It should be possible indeed to reach that percentage. Quick follow-up question. Are there, apart from translating itself, any other steps we will need to take? And imagine the translations reach the treshold, how long would it take before we would see the Vietnamese lanuage present in the app? Is it something that takes days/weeks/months? Thank you for everything!

Once the threshold reaches 50%, it’ll automatically be added into QField itself and included in the next version.

Hi Mathieu. I have a follow-up question. Together with my Vietnamese colleagues we translated a first batch of strings, and it looks like we have surpassed the 50% threshold (https://app.transifex.com/opengisch/qfield-for-qgis/language/vi/). Since a few weeks, there’s a vietnamese ts-file present in the project too ( QField/i18n/qfield_vi.ts at master · opengisch/QField · GitHub ).

After updating QField to the latest version, however, I don’t see Vietnamese available yet in the languages dropdown-menu. Do changes like this maybe only become available with major updates? Or is there anything else I miss?

Thanks a lot in advance for your help.
