    So today was the hottest day of the year in the UK and the hottest since 2006.

    I was out and about enjoying the weather. The TouchID on my iPhone was totally inoperable. I guess I understand why, it's due to moisture on my digits. But my question is what on earth do people do in Florida, Asia and Australia when it's like that most of the time, just don't use it?

    Maybe I shouldn't poke my fingers where they don't belong.

    But wiping is a pain in the backside [ahem]. Does everyone in hot countries have to do that all the time?

    I noticed these problems too. Even slightly unnoticable sweat on fingers make using touch id pain in the ass.

    mine doesn't work if my fingers are not perfectly dry.

    so the slightest hint of sweat will more then likely make it not work.

    Edit: I see I basically just said exactly what the person above me said.

    its normal. even if your hands aren't sweaty. but hot and not perfectly dry. it could take more than 1 try or it doesn't work really

    It's been about 90° with 80% or more humidity for the past 3 weeks, so I've been manually entering my passcode quite a bit.

    I have issues with it working whenever it's really cold too, because going in and out from cold to warm makes my hands clammy.

    I live in hawaii. Welcome to my world. Whether I am on the beach, or fresh from the gym Touch ID is inoperable for me.

    Even on just moderately hot day I have issues sometimes.

    I've thought about this too myself, as I am a profuse sweater. I often have to figure which of my four fingers is the "cleanest" and still wipe it down some to get it to work. And if I try with wet fingers I often leave some on the button meaning I have to clean it with something as well.
