It depends on your device. The first requirement is for your Galaxy phone to actually still be eligible for that update.
Recently, Samsung has been the only Android phone maker to offer four years of software updates, and that promises started with the Galaxy S21 series, so even those older Galaxy S21 models are eligible for One UI 6.0.
The latest versions however will receive it earlier, so we expect the Galaxy S23 series to be the first to get the Android 14-based One UI 6.0 around October, with the Galaxy S22 and Galaxy S21 series expected to get the update by the end of the year (as per our projections, Samsung has not specified an official timeline just yet).
