It has been less than a week since Samsung announced the Galaxy S22 series and as expected, all three phones do support a 120Hz refresh rate, however, the displays are not as similar as you may have expected. At the time of the announcement, Samsung announced that the Galaxy S22 Ultra can go as low as 1Hz and all the way up to 120Hz when it is needed while the S22 and S22 Plus screens would go as low as 10Hz and then back up to 120Hz.

This is done to ensure that there is battery saving. Samsung has decided to change that because they have recently updated the Galaxy S22 and the plus variant's screen specs and mentioned how they can only go from 48Hz and 120Hz. If you head over to the product page, you will see how Samsung has changed this information.
