@ramirowski For NFC try fresh 4.4.4 stock ROM install and boot it. Once booted it will update something regarding NFC. After that try to install MIUI. I don't know will it work or not but maybe... Yeah, I have same issues with Facebook and Messenger. I already got back to stock. Just ordered Xiaomi Mi4i for $140 few days ago at jd, there is a promo discount there.
