I am using Arnova's Advanced 1.5 based on 6.1 with the config file from Xiaomi Mi9 (Marian---XLib2.2s---P3XL---Test2.xml) because we share the same main sensor. I did not have time to test it properly for quality but the functionality is fine. If you want an older one you could try Tolyan's latest version based on 5.3 but you need to config it manually.
