The unity remote app runs an editor version of your game on the device basically it just uses the display and input of the device but runs on your pc/mac. So if you want to test any device specific code it must be run on your device or an emulator for it to come out perfectly. Furthermore i noticed the touch input on the remote app and on emulators are sluggish so values for tweaking gestures must be run on your device only to get the right values. Hope i helped :)
