Hello, thank you for your porting first.
I'm using zenfone selfie(z00ud)
after I finished installing,
my first thing to do was to see whether the screen is flickering.
The screen's boarder flickered like an old lamp in any circumstance display...
How to create the selfie mode shortcut (can't find this activity shortcut with nova launcher)
Some versions don't have the shortcut, but Arnova's versions can be created,
on nova, you can use "sesame", it can help you find the shortcut....
Didn't see much difference on hdr+
My device is Asus ZenFone Selfie (ZD551KL) (ASUS_Z00UD)
When I flash lineage os 14 or cm 13,
the screen border always flicker(I don't know how to describe it)
But when I use stock rom it never happen.
I don't flash any zip I only flash the ori...
