Topjohnwu, the developer shared how difficult it was to make the MagiskHide flawless on Android 10 due to Google’s slew of under-the-hood changes. He has reworked the Magisk base to work in accordance with the changes made by Google in system-as-root. So, starting from the Magisk 19.4 Magisk will follow how Google has designed system-as-root: mounting system actually to / (root). Plausibly making the MagiskHide to function atleast in A/B devices.

Unfortunately, the MagiskHide for A-Only devies on Android 10 is still a mystery. The dev hasn’t yet figured out how to make it possible despite Android 10’s biggest challenging aspect –  the 2-Stage-Init” system-as-root implementation. Well, we hope the dev to come up with a solution asap. Till then, the A-Only device owners have to adopt the Magisk in Recovery method for rooting.
