For me it's not exposure to water, it's my health. When more ill than usual I can't get my smartphone to work properly. If I can even get into it, as the fingerprint sensor says I am not me, and, what with the screen being 'unpredictable', it can be more trouble than it's worth to get it to accept the phones password.
Other infuriating, and impossible, things go wrong, things that I couldn't do if I tried to (like the phone switching to camera mode whilst I am attempting to compose an email, when there is no camera button, nor icon, on the email screen), and completely closing the email app, losing what I may well have spent hours trying to compose, but basically, neither the phone, nor cats, like me much when I am ill ill.
