Developers and daredevils are in the middle of the beta of iOS 14, but Apple is also still working on the current public version of iOS. Recently iOS 13.6 appeared for the iPhone, but now the subsequent update iOS 13.6.1 is available.
iOS 13.6.1 available
With such minor updates, Apple usually fixes a few known and unknown bugs and improves security. iOS 13.6.1 has not been tested as beta in recent weeks, so we did not know in advance what exactly has been resolved and what may have been adjusted. Apple says that the green haze at the iPhone 11 screen has been resolved with this update.
