Are u blindly believing youtubers? Please don't. #samsung gives #OneUi"Core" in M30s & not a single Youtuber ever mentioned it.
One ui "Core" is a stripped down version of "One Ui", many mainstream samsung app won't support on it.
actually speaking, there will be goodlock available in the future even to m30s. As u c, m20, m30, etc even has one ui core, but supports goodlock including all of its plugins. So, v can conclude that goodlock supports even on one ui core wait for Android 10 update with One UI 2.0 Core on M30s
Samsung M series is based on one ui core ,so all the models like m30s and m31 are based on core version .But in the core version samsung has removed some features like knox and other features that's why they sell m series at cheap rates to other series.
