Front Facing Camera not detected, even by third party apps

[BuBu Shofronea]

I just installed CM13 Official SNAPSHOT 20160816 and i'm facing a weird issue that i cannot access my front facing camera by nothing in this universe. I ran Antutu and it just detects my back camera. I'm using a Xiaomi Redmi Note 3 Pro ( snapdragon ). I reflashed the MIUI ROM and back there the front facing camera had no issue at all.
I installed the CM13 this way :

Flashing thru fastboot latest global RN3SD ROM with Mi Flash
Unlocking bootloader with MiUnlock
Flashing TWRP 3.0.22 with Flasher Toolkit v1.05
Updating to TWRP 3.0.M4-0 with adb
Factory reset + wipe system/dalvik/data/cache
Flashing CM Firmware
Flashing CM13 Official ROM
Flashing Gapps NANO ARM64 6.0
Rebooting.
