Would be good to see Samsung add a lock screen depth customisation via lockscreen edit and more features. Just feels a little stiff in regards to the smoothness when editing and customisation with wallpaper and lock screen.
WITHOUT having to have the hassle of going onto an individual app such as a Goodlock. Seeing as most Android and even Apple have a depth effect within their simple edits via lockscreen.
Considering your post focuses on Apple, the obsession isn't with me. Perhaps leave feedback with support as I suggested, this is a user forum post and support are less likely to frequent here for software feedback.
