Lagging issue appeared on Samsung Galaxy Note 20 Ultra after Android 12 One UI 4.0 update

Later last month, Samsung started rolling out the official Android 12-based One UI 4.0 stable update for Galaxy Note 20 series devices in several regions. However, it looks like the major Android OS upgrade has some bugs or issues that occur performance and/or animation lags.

In contrast, a Galaxy Note 20 Ultra user recently reported on the community forum that he’s facing lagging issues on the smartphone just after upgrading to the One UI version 4.0. Additionally, the user said that the performance lag happens while scrolling and shifting between apps.

Due to this issue, the Galaxy Note 20 Ultra smartphone users are quite disappointed as they are waiting for the Android 12 and One UI 4.0 update for a long time. And the arrival of this type of performance issue obviously lessens the user experience.

However, some users shared a possible way to get rid of this issue, that is as follows:

The users state that, after a major update, the OS re-indexes system files in the background, then you may experience some lag and thermal issues. Users say to calm down and see if the lag is still occurring after a few days. If so, you can do a factory reset.

On the other hand, another user commented that he has waited for over 12 hours for indexing to complete and tried a factory reset, but it didn’t work either. At this point, users have come to the conclusion that they should wait for Samsung to fix the bug with future updates.
