I use a cheap (the least expensive and sophisticated I can find) cell phone. I had mine in my pocket the other day, 'cause I intended to make some calls after work... But I was tired and when I took off my trous to shower I dropped them in the washer, 'cause I had no clean ones with me, as I shower away from where I dry camp....
OOOPSSS! Cell phones ought not to be washed... $30 to replace the phone... I didn't plan to spend yet!
The worst part? Losing my contacts file!!
