Yeah, it doesn’t.

You can also try LineageOS GSI for the time being.

Heliboard is the best opensource keyboard I have used. For dialer, I use fossify Dialer

KOreader is the best

No need for tasker, you can achieve the same thing by enabling rotation icon using systemui tuner and adb.

Lawnchair has google feed. And I think Nova has too.

Yes, I have done it multiple times but you will lose recents screen and gesture navigation. If you have root, you can get it back with lawnchair + quickswitch.

GSI are dominant now, device specific Roms are rare these days.

• You can’t revoke android.permission.INTERNET at runtime. You can only revoke at install time. Since you don’t have root you can’t revoke that permission.

No, if you have another launcher installed with quickswitch support (like Lawnchair). Then you will be fine.

Note: QuickSwitch requires root. It’s for gestures and navigation support.
