Samsung One UI 4.0 (Android 12) Update Bugs, Issues & Issues Tracker


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

The original story (published November 23, 2021) follows:

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

The first phones to receive the update include the Galaxy S21, Galaxy S21+, and Galaxy S21 Ultra. As expected, the latest version brings several new features focusing on personalization, privacy, and tighter integration with other Samsung products.

What is surprising is that this time the release of One UI 4.0 does not coincide with the launch of a new flagship phone. Nevertheless, 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 compared to last year, which is a very good sign. Samsung has also confirmed that it will soon bring One UI 4.0 to the latest generation of Galaxy S and Note devices as well as Galaxy Z, A series and tablets.

However, not all features may be available on all devices running One UI 4.0 due to hardware limitations. Despite this, One UI 4.0 is a significant upgrade over its predecessor as it carries over several new features such as Theme Engine from Android 12.

That said, if you want to know which devices will get One UI 4.0, be 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 future releases. That being said, we will be keeping track of all the bugs and issues that eventually appear on One UI 4.0.

We hope Samsung recognizes and fixes these issues so that users can enjoy One UI 4.0 as intended.
