Inconsistency: Card numbers are not shown in groups (while in the other BW apps they are in groups of four)

[pamperer562580892423]

Steps To Reproduce

1. Go to an existing Card item with a Card number - or create a new Card item with a Card number.
2. Open the "View item" view for that Card.
3. Toggle visibility of the Card number.

Expected Result

Card numbers are grouped - like in the browser extension, in the desktop app and in the web vault.

Actual Result

Card numbers are not grouped. An inconsistency, as they are grouped in the other BW apps.

Screenshots or Videos

Android mobile app (2025.4.0) - the numbers are NOT grouped:

 

Browser extension (2025.4.0) - the numbers ARE grouped:

 

(Windows) Desktop app (2025.3.0) - the numbers ARE grouped:

 

Web vault (2025.4.1) - the numbers ARE grouped:

Additional Context

I just used eight "groups" of four numbers for visualization. - Of course, that is longer as a normal card number. I found it interesting though, that the "grouping" stops also in the other three BW apps after the fourth group. I'm not sure, if there are (or ever will be) longer card numbers than now, so I'm not sure if the grouping for more than four groups of four numbers should also be adapted in all BW apps?!?

Issue Tracking Info

• I understand that work is tracked outside of Github. A PR will be linked to this issue should one be opened to address it, but Bitwarden doesn't use fields like "assigned", "milestone", or "project" to track progress.

Only, that the same issue seems to also be the case for the iOS mobile app - see this post: https://community.bitwarden.com/t/credit-number-not-in-groups-of-4-digits/84823/8
