Samsung Galaxy S21, One UI 4 has an annoying bug: but there is an update that solves it
The three Samsung Galaxy S21 are perhaps more interesting devices today, with the hefty Black Friday discounts and the upgrade to One UI 4 based on Android 12 cool that makes them among the first smartphones to receive the latest version of the green robot not only in the Samsung catalog but in general in the Android landscape (after the Pixels, of course).
In any case, the transition to One UI 4 also started in Italy last week starting from S21 Ultra, was not entirely painless, as often happens for major updates, those that upset numerous aspects of the operating system. Specifically, there is a bug in particular that users have promptly reported, and which appears to be particularly widespread, albeit it would especially affect Galaxy S21s with Snapdragon 888 SoCs, and therefore in Europe (where the version with Exynos 2100 is marketed) should not have the same incidence as in the USA.
