[Update: Jan. 27] Samsung One UI 4.0 (Android 12) update bugs, issues, & problems tracker

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

Original story (published on November 23, 2021) follows:

A few days ago, Samsung announced the official launch date for its upcoming Android 12 based skin named One UI 4.0. Unsurprisingly, it is available on the Galaxy S21 series.

The first phones that received the update include the Galaxy S21, Galaxy S21+, and the Galaxy S21 Ultra. As one would expect, the latest version brings in several new features that focus on customization, privacy, and tighter integration with other Samsung products.

What comes as a surprise is that this time the release of One UI 4.0 does not coincide with the launch of a new flagship phone. Nonetheless, the company is already rolling out the stable version of One UI 4.0 to some devices.

Looking at the current state of things, we can see that Samsung is a month ahead if we compare them to last year, which is a really good sign. Samsung has also confirmed that it will soon bring One UI 4.0 on the last generation of Galaxy S and Note devices as well as to the Galaxy Z, A series, and tablets.

However, not all features might be available on every device running One UI 4.0 due to hardware limitations. Despite that, One UI 4.0 is a significant upgrade compared to its predecessor since it picks up several new features such as Theme Engine from Android 12.

Having said that, if you are interested in looking at which devices will be getting One UI 4.0, make sure to check out our dedicated One UI 4.0 update tracker.

But, as is the case with every new software update, some bugs and issues will need to be fixed in the upcoming versions. With that being said, we will be keeping track of all bugs and issues that eventually surface on One UI 4.0.

We hope Samsung will acknowledge and resolve these issues so users can experience One UI 4.0 the way it is intended to be.
