The presence of an aqueous liquid is not proof that it entered in

Indeed, I have come across this, once. That was someone who worked
in a cold store and was going from -25deg C to +20 several times a
day. They kept their phone on a string around their neck so they
could answer it while wearing mittens.

The cumulative effect of
repeated heating and cooling cycles (as in day and night) may
result in an accumulation of a damaging, or at least indicating,
amount of water that never entered in that phase and form.

The thermal mass of the phone is far too small for diurnal variation
to cause condensation. If the phone was normally kept in a very cold
environment and then placed in a pocket it may occur but it is very
improbable.

In normal use no , but many people take/leave phones in bathrooms and
ktchens where they are subject to massive changes in humidity very
quickly , have them dangling round thier necks whilst consuming hot
drinks this will hav an effect on phones , even ansering them in the
rain , realisically you would think the phone manufacurers would make
the things more water resistant considereing they are for outside use
