Hello op. Nope I didn't flash any custom kernel. The issue is with snap camera and arnova build 6.2 v1.7( the only I could test). The Open camera app works just fine and the GCam from this thread worked:Did you flash any custom kernel? use tr cam
There is one more new bug:
The Swype gesture on AOSP keyboard don't work. I use opengapps nano. It installs Swype libraries but it no Swype typing. I found a solution by replacing it with older Android 9.0 version from apkmirror of LatinIME by Lineage OS.
Overall solid ROM op. Has few hicups in animation here and there but its the hardware limit of the device I guess. Thankyou for such a clean AOSP experience.
