Recently the home but has become very slow on my S7 on noughat, sometimes there is a delay up to 3 second between pressing it and anything happening, any ideas?
Not sure if the bug is still there or not, but try clearing out the contents of your clipboard. I know, I know... don't ask me why it has to do with the clipboard, it just was a bug haha
Disabling S-Voice or resetting the home button shortcuts (double tap for camera, triple for one-handed mode) might help too.
