Samsung starts testing One UI 6.1.1 for Galaxy Z Fold 6 and Flip 6

The S24 series ships with One UI 6.1 out of the box. Other compatible phones will get the update soon, around March or April. There are many reports of leaked firmware numbers of internal testing builds of One UI 6.1 for the S23 series. Meanwhile, other devices are getting the February security update on One UI 6. However, Samsung is also developing the One UI 6.1.1 security update.

One UI 6.1.1 is particularly aimed at Samsung phones with larger screens. It might not be a major feature update, but phones like the Z Fold 5 and Z Flip 5 might get it later with minor tweaks. The 1.1 version of this update is out internally for some Samsung foldable phones and tablets.

Samsung is developing One UI 6.1.1 for their next generation of foldable phones. We expect the Z Fold 6 and Z Flip 6 to ship with One UI 6.1.1 out of the box. These phones will carry mostly iterative improvements, like a potentially larger battery for the Flip. We expect an S-Pen in the Fold, a better main sensor, and performance improvements.

According to a post from Tarun Vats on X, Samsung is developing a version of One UI 6.1 for the upcoming Z Fold 6 and Z Fold 6. The model numbers for these two match here, too. F956 for the Z Fold 6 and F741 for the Z Flip 6.

Update firmware numbers

  • Z Fold 6: F956USQU0AXB3
  • Z Flip 6: F741USQU0AXB3

starts testing One UI 6.1.1

This is apparently early test firmware for both of these phones. It’s on the server, and we expect the Fold 5 series to get the One UI 6.1.1 soon. There’s no information on when the S23 and S24 series will receive this update.

Samsung will mostly announce the Z Fold 6 and Z Flip 6 at the Galaxy Unpacked event in July 2024. It will mostly have this One UI 6.1.1 version out of the box. If Samsung announces the Galaxy Tab S10 series at this event, they’ll have this version. The existing Tab S8 and Tab S9 series will eventually get the update.
