Ack, I wouldn’t want it to keep making noise - the noise is annoying but necessary. I generally tap once to get a general bearing (”ah, I must have left it in the kitchen when I went in there for a moment”), then walk closer, and if the phone isn’t immediately apparent, I tap again to get a finer grained idea of where it is - I much prefer this to something that keeps blaring until I turn it off.Except of course there couldn't have been a worse implementation: Why is the phone not flashing? In the dark this would help a lot. Why is the sound so short? I'm looking for my phone, keep it going until I find/move the phone or turn it off on my watch.
And why is the phone not flashing? You don’t seem to be aware that if you hold down the button on the watch, you get flashing as well as noise. They could improve this by flashing the screen as well as the camera flash, to make it show no matter which side is up, but it’s a useful feature as is.
