If you do not want to wait for the new release .... I did as Ups2k says and that is: I took boot.img file in the jacobi zip of the 18-4 and copied it into the 27-4 zip - made twrp flash without wiping over my Rom and frontal room are ok and the video tooWell, i want to revert back to where i can use video recording even my front cam is upside down but i can't, "persist.camera.HAL3.enabled=1" disappeared on my build.prop. even if i put it, my front cam is still the same(normal/not upside down), video recording always crash. I am willing to sacrifice front cam just for video recording. Any fix for this?
