This is gonna sound kind of weird but condoms work very well for this too. Nonlubricated only though

Dang, you are right! I bet they work even better.

Awkward in some situations, maybe :-), but an excellent technical solution!

Good point. Don't use a bag with holes! Condensation can't happen inside the bag, since there is almost no air in there, and the phone itself is not cold.

This is a quick fix. If you are going to get your phone wet regularly, by all means, get a waterproof case. If this is a last minute or one-time thing, it is much better than nothing.

Think of this like a spare tire. You shouldn't use it as your everyday tire, and you have to be more careful with it than a regular tire, but you glad you have it when you need it.

It is a resourceful idea, but I'd weigh the risk of trusting an expensive device to an inexpensive baggy.

I suppose it will work IF: the bag doesn't have or later get any holes in it, the zip stays zipped, the zip doesn't leak, there isn't any problematic condensation inside the bag, etc.

If you keep a double-zip freezer baggy (they are a bit more durable) with you and want to throw your wallet & phone into it if you get caught in a downpour, that is quite sensible. But I wouldn't go swimming with your phone in a sandwich bag.
