1 Glitchy App Icon Placement
Another widespread bug that iOS 11.4 deals with concerns app icon placement. The bug caused certain apps on the Home screen to appear outside of the usual grid — often hovering above or even partially behind other apps. The bug persisted routine reboots and system restarts.
Users also reported being unable to delete or otherwise move the out-of-place app icon. And based on the number of people who reported it, it was fairly widespread and received quite a bit of attention. As with the other bugs on this list, iOS 11.4 does away with the problem.
