Made some progress with AUX now all 3 lens are supported, 60 fps video recording modes now work, 30 fps works fine just a bit laggy in Viewfinder (EIS might work I am not sure since I don't own the device). To switch to wide lens just press the camera switch button (the same button you use to switch to front camera) twice (once for selfie cam and once to get to ultra wide). Link in 1st post
I followed above mentioned video to adjust setting of the gcam. Settings are good, but i wasnt happy with overall result as it seems there was a little bit noise on pictures taken indoor and contrast was high, especially on photos with human faces on it.
So I adjusted mentioned settings a little bit, and results now are slightly better. At least from my point of view
I'll post my config here, you are free to test it and more than welcome for any suggestion or change of settings.
Gcam used is 7.2 Urnyx05 v1.8
Pixel AWB in HDR+ Enhanced is set on IMX586 for low light/indoor photos, and set on Off for daylight/outdoor photos.
