The 100x Space Zoom currently supported by the Galaxy S20 Ultra sounded extremely promising on paper, but with lots of reviews calling it nothing more than a gimmick, perhaps it was high-time Samsung focused on other areas rather than marketing those large numbers. A tipster believes that while the Galaxy Note 20 Ultra won’t support 100x Space Zoom, Samsung is expected to make much-needed improvements elsewhere.

Samsung was earlier reported to skip the 100x Space Zoom feature when announcing the Galaxy Note 20 series. Now, Ice Universe has come out with a tweet stating that the maximum zoom limit on the Galaxy Note 20 Ultra is 50x rather than 100x. He gives a solid reasoning to this; Samsung wants to focus more on the experience rather than diverting its attention to those big numbers because we all know how well that played out.
