Why no info about removed CPU frequencies?
Comparing to V8, now little cluster have only two to choose (691 and 1708 MHz), there also many removed frequencies from Big and Prime clusters.

Getting a FOD flashbang issue on V9 NewFod. Have to set the brightness manually after using the fingerprint, else the brightness just stays on max (despite it being set to whatever it was before on the slider).

Hi, I would like to know if the GPU is overcooked?


I've just seen that on CPU-Z app it's displaying "670 MHz" and

I researched online and it says that the stock setting is "587MHz"

Is there any problem to let it that way?

Thank you so much for this awesome Kernel! It's super smooth with Pixel Experience (baked-in on PX)!
