I find that reliably activating this feature is impossible for me. I pretty much always have to try at least twice to simply just hold the home indicator correctly. On the Home Screen it works OK, but when I’m in apps, they slide up a little like I’m trying to activate the switcher.
I’ve basically given up on it and I want to change Circle to Search activation to possibly a double-click of the power button. Is this possible without root? I don’t mind using ADB.
