I'm writing this article very late almost 2-3 months after the update
These are the changes I noticed in OneUI 6.1 on S21 FE. Though there are minor changes S21 FE didn't receive the AI features. Though here are some minor changes
Previously this used to be Bixby text call but now it has been renamed as Text Call
This battery protection is a new feature on oneUI 6.1. Previously there was option called protect battery which would only stop charging at 85% but now some more options have been added
Wifi hotspot features have completely changed from OneUI 6.0 but now in this OneUI 6.1 there's this lock hotspot feature where already connected devices are only used to allow to use your phone's internet but new connections are not allowed
