mrddu3at2End of an era: Nova Launcher's parent company lays off practically everyone
There’s a bug on samsungs (I think) where the home screen interface freezes, and the only way to unfreeze it is to relaunch Nova. It’s super annoying. This probably means it will never be fixed.
grayhazeThe quickest way to fix it is to lock and unlock your phone by pressing the power button twice, but not too close together or you launch the camera.
