I can’t recall false positives being a huge issue for me, but it’s very late at night so my memory might be foggy.

I honestly don’t use it a lot because I have a gesture which enables me to swipe down on the home screen to bring down the notifications and I’m just so used to doing that. Personally I have to adjust my grip to use the back tap feature, so it’s slightly inconvenient.

Having the flashlight on the feature is something that I would like but unfortunately it’s just somewhat embarrassing to walk around with the flashlight turned on and false positives are a problem here.

With the notification shade false positives don’t really matter.
