I don't have enough time so I can only try it with Dirty Flash,
The latest builds(AOSiP-10-Official-potter-20200618.zip) are very smooth. very fine.
(also I already tried the 20200611 build too, and it worked fine)
After Flash, swipe operation of the fingerprint sensor did not work,
but I was able to cope by turning off the On-screen navigation bar in setting menu "OwlsNest>Navigation".
The number of rows/columns of the QS tile has returned to the default,
but I have set it again with OwlsNest to deal with it.
About FMRadio.
The situation of FMRadio has not changed, but I noticed one thing.
When I plugged in my headphones or headset and started FMRadio app,
The microphone device was enabled and it was picking up the sound properly,
I heard it through the headphones and headset.
There's no such thing as "so what" ...
