If you would like to have your apps sorted on the Samsung Galaxy S6 in alphabetical order, then you might have problems to find this setting. That's not surprising. Because Samsung hascompletely removed this useful feature from the TouchWiz interface. This means in plain language that on the Samsung Galaxy S6 there is no way to sort the apps in the menu automatically in alphabetical order.
You can only sort apps on the Samsung Galaxy S6by tapping in the upper right on "Edit". Then move the apps to the position you want by hand.
We and many other Samsung Galaxy S6 users hope that Samsung will incorporate such useful functions as the “sort function” again in the next firmware update. Until then, only the manually variant or using another launcher, such as Nova the launcher, is possible to sort your apps.
