Camera - Miui 8 And Xiaomi.eu Miui 9

[Grabowac]

Hi guys,
My bro has unrooted Redmi Note 4 Snapdragon with MIUI 8 installed.
I have the same phone, just Xiaomi.eu MIUI 9 rom (from this site) installed.

I noticed, that MIUI 8 has better camera.
Front camera on MIUI 8 has not that much noise, as the camera on my phone running MIUI 9 off this site.

Are there big differences between those two roms? I mean, something "that big", that changes the camera by that much although both phones are running MIUI.

Thanks!
