There’s another thread “Oneida Lake kayak incident” in which a kayaker got into trouble in cold water. One of the kayaker’s poor decisions (in hindsight) was that he didn’t want to use his phone to call for help because he was afraid he’d lose the phone.
That got me thinking that perhaps there are folks who don’t know that you can get a clear, waterproof pouch for your phone that allows touchscreen use through the pouch. And for the one that I have, I’ve tested it and I can hear and be heard by a caller if I use the speakerphone, and the touchscreen function works with both the outside of the pouch and my hands wet. I keep mine tethered to my kayak but it would be even safer tethered to your body (I have a VHF radio tethered to my PFD).
This is probably not new news to most regulars on this forum, but maybe this post will help keep someone safer.
FYI, there are many such cases out there. The one I happen to have is shown below, and I only chose it because it was on clearance at Dick’s Sporting Goods a few years ago:
