As you all know Gcam is not working on miui 10 builds. For now, we know "fix for it " i tried it on xiaomi.eu 10 stable build and it is working.
1. Download build pro editor from google play
2. Open build prop editor click on three dots in right up corner press + New - Name : persist.camera.HAL3.enabled and in Value field enter number 1 and click save.
3. in prop editor go to search and type persist.camera find this line - persist.camera.dxo=1 and delete it. Restart the phone. Now boot to twrp and flash camera fix for gcam and boot again.
4. Install Gcam you think will be good ( I tied it with OP6-1.2.1-Gcam and Gcam 5.1.018 by SerJo87)
