A lot of users have already received the updates on their Note 4, some have installed it while some are yet to install it. Note that there is bound to be a bug at first installation of this update but Infinix will possibly roll out a system update to fix the bug.
Like I said earlier, before you update;
1. Make sure your device is not rooted otherwise it will get bricked
2. Make sure you have a back up of your current firmware should in case the need arise to downgrade your device if the update contains bugs
3. Ensure your phone battery is atleast 95% charged
4. You need upto or more than 2GB to download the update
