wizwi In the next QPR2 update, Android will get local parental control functionality via pin code.
Perhaps... though I think desktop mode is most of two years late by now... and I think app cloning was widely predicted but didn't ship.
wizwi Is there a chance we will see this in Grapheneos?
If/when Google ships it as part of AOSP (meaning: if Google doesn't keep it as a feature restricted to their Pixel version of Android) it is very likely to end up in GrapheneOS.
Overall, it's much too early to say.
