Apple seems to be working very hard on improving its last major iOS update. Just after a week of releasing iOS 10.1, the Cupertino giant has now pushed another update (though a minor one), the iOS 10.1.1 to iPhone and iPad users.

The minor update addresses several bugs with a primary focus on resolving an issue with the Health app.

Besides resolving the Health app problem, the iOS 10.1.1 also fixes several other bugs, however there's no detailed information about them on the software update page.
