Samsung's One UI 4.0 upgrade beta program is now officially released in full operation, and users shouldn't have to wait a long time for a completed version of the software to hit the streets.

Furthermore ,the Samsung One UI 4.0 released date will be coming sooner.

One UI 3.5 will define the vast majority of design modifications, additions, and features that One UI 4.0 will deliver.

However, enthusiast speculated it will likely include a larger number of new features.
