Xiaomi is taking its own time to update the Redmi Note 3 to Nougat. Actually, even if it does arrive MIUI will limit the features making it essentially useless.
For example, MIUI does not allow you to customize the font styling in WhatsApp. On a normal Android OS, you can long press on text, and select Bold, Italic, etc.
There are more reasons why you should opt for a custom ROM. Root, and in turn Adaway, Titanium Backup, Android Firewall + (AFWall+) for privacy management are some examples why you should. More control, more customization, etc.
While LineageOS is good, we have had plenty of bugs affecting our daily usage, and would like to recommend an alternative ROM, Nitrogen OS. Besides working VoLTE, Camera, Flashlight and a stable performance, it has a lot of personalization options, and the developer options and root are pre-enabled.
