Works great on my Galaxy S3, with KitKat 4.4.2. I've mapped the Google app to a double-click, which gives me easy access without using the Google Now Launcher. NOTE: IF you're having problems on a Galaxy device, make sure you disable "Open via the home key" in the S-Voice app settings. If you don't do that, then Home2 won't bring anything up on a double-click, even if you turn off S-Voice.
It works. Great app. It seemed not to work after the kk 442 update for the Samsung GN3. But if you enable and open Samsung's s voice and disable the home key to open option and re-disable the app it will no longer interfere with this great customization. Thanks to +Stephan Sanchez on G+ for pointing this out. I use it as a quick double tap of the physical home key to Google Now. Edit:doesn't work well with Nova launcher but wasn't really necessary.
Does what its supposed to do... But poorly. I have a droid turbo running 4.4.4 and the shortcut works but every time I press my home key I see my multitask menu for a second. I understand this is the app waiting to recognize a second home key press, but it wasn't always doing this. An official release of this app would be nice. If I get a reply I might donate.
Works... (kind of). I used this on my Galaxy Note 3, and at first it didn't work. However, after I downloaded Nova Launcher, the shortcuts worked. My guess is that the app doesn't work when you have only a TouchWiz skin. I'm not sure why. Anyway, good job to the developer. A good app, definitely worth a download. I used it to get a Google Now shortcut instead of Samsung's S-Voice.
Some bugs on Samsung Devices Double Tap Home still launches Samsung S Voice unless S Voice is disabled in application Settings. Also, when mapping Google Voice Search to double tap home, it instead launches voice dialer. I think it has to do with the way Voice Search is called, since a bluetooth headset behaves similarly when calling Voice Search. Running on my Samsung Galaxy S Relay 4G with Android 4.1.2. P.S. It would be nice to have a feedback option where we could send bug reports to vice just putting them into reviews.
Sheer genius, incredible function added. Cons: interface is not the easiest to setup. Pros: doesnt matter. Set it up once and you are set. Using this app in combination with Google Now, google now actually necomes useful. It is only a brief button click away thanks to this handy app, lending android devices Siri-like voice accessibility. If I had to pay for tgus app, that would be ok. It would be worth it.
