I had that problem once too, i went to school in my swimming clothes and when i got home i jumped in the pool. I was like 11 or 12 back than and had an old samsung flip phone haha. After 1 hour i got out the pool and was like 'Uhm... Dad?! My phone is still in my pocket!!' He thought i was joking, but we lay my phone in a bag of rise and after 2 days tried to turn it on. Didn't work, but oh well they gave me a new phone instead hahaha!
