Small Design Tweaks
Though not necessarily “features,” Apple made a variety of small design and UI changes in iOS 12.2. That includes a new Apple TV Remote icon, a new Screen Mirroring icon, a new Airplay icon, a new Apple News header, and a new Apple News icon. There may also be a new misleading “5G E” icon for AT&T users, but the telecom firm has faced some flack for it.
Update: iOS 12.2 was officially released to public on 3/25. Please see details here.
