Hi,
Suddently i lost the folder of /system/etc/device_features/ of my redmi 4 prime, please help me upload the copy of markw.xml I relly need it for add manual mode on stock camera
You can added persist.camera.HAL3.enabled=1 in your build.prop file to enable camera2 API, so you will be able to use manual camera(focus, exposure, raw photos) (not in stock camera tho)
It works fine in my redmi 4 prada
