  • My New Favorite Launcher
    Just checked, the neo launcher I use is not on the play store, although there is some other "neo launcher hyperion", thats not what I meant. If you want to try it out, you'll have to get the apk directly from their github (https://github.com/NeoApplications/Neo-Launcher) or get the F-Droid store & activate the IzzyOnDroid repo (https://apt.izzysoft.de/fdroid/).
