[Update: Feb. 17] Samsung Galaxy A Series One UI 4.0 (Android 12) update status: Here's what we know

New updates are being added at the bottom of this story…

Original story (published on September 04, 2021) follows:

Samsung has been overly quite about its Android 12-based One UI 4.0 update which is currently in the beta testing phase.

While the One UI 4.0 beta is being tested for the Galaxy S21 series devices, the OEM has a vast portfolio of Android 12 eligible devices.

Among them, several devices from the Galaxy A Series which are also part of Samsung’s three Android OS updates program.

This means that some of these devices will get OS updates till Android 14 whereas some new entries may get the same till Android 15. It is, however, unclear which newer entries in the series are eligible for three Android OS updates.

Apart from that, a bunch of Galaxy A Series devices are indeed in line to get the upcoming One UI 4.0 (Android 12) update. So, here’s a list of devices from the series that we believe will get the upcoming OS update:

– Samsung Galaxy A71
– Samsung Galaxy A51
– Samsung Galaxy A90 5G
– Samsung Galaxy A11
– Samsung Galaxy A21

– Samsung Galaxy A21s
– Samsung Galaxy A31
– Samsung Galaxy A32 5G
– Samsung Galaxy A02s
– Samsung Galaxy A02

– Samsung Galaxy A01
– Samsung Galaxy A12
– Samsung Galaxy A42 5G
– Samsung Galaxy A41
– Samsung Galaxy A72

– Samsung Galaxy A52
– Samsung Galaxy A52 5G
– Samsung Galaxy A51 5G
– Samsung Galaxy A71 5G

Since Samsung has not yet shared any timeline or feature details for One UI 4.0, it is unclear what the OS update will bring for the Galaxy A Series devices.

However, considering how the OEM has been doing on the software front, the upcoming Android 12-based custom skin is expected to bring many improvements and features.

To recall, reports indicated that Sound Assistant support for DeX on eligible tablets might be added with One UI 4.0 along with redesigned apps, new animations, and much more.

Thus it is safe to assume that the upcoming OS update from Samsung might bring major changes to the eligible Galaxy A Series devices as well.

However, all this is still based on speculation until the OEM shares more details regarding the One UI 4.0 (Android 12) update.

Also, Samsung will first focus on updating its flagship devices to One UI 4.0 (Android 12) before moving on to other eligible devices.
