It is really good, all customizations I liked is in here. But there is just one problem I happen to encounter, idk if you fixed it on later versions but mine (Corvus v.10 on Lenovo Z5s) the calls are not ringing. The ringing takes place only in a second then gone. I've tried calling again then there is the ringing. The ringing only lasts after the first call, I've tried it many times on how could I fix the first call ring but I can't. Please address to this problem. Thank you!
PS. I'm just new to the customizing os's, this is my first time installing one and yours is good. I like it and I'm a fan.
PPS. Hope to see your android 11 or 12 soon. :)
