Re: the use of fingerprint unlocking forces you to de-glove anyway
My Nokia 6210 screen (monochrome LCD dot matrix) would be slow in cold conditions (in a rucksack in the snow). The phone remained usable, but pixels took around 0.5 to 1 second to change state.
Had the phone been in my jacket pocket it would have been warmer (I was snowboarding, so didn't want a lumpy hard thing to fall on).
