This has never over the years been asked or discussed over on Toss. How about a 4 ounce recycled platform? I just was passed a new Samsung Smart Phone from work, a few weeks ago and moved over my contacts. I cleared off and reset my old Waterproof Rugby Samsung. I reinstalled all the old apps and a new one Back Country navigator. This factory reset brought the speed up and I am installing a chip with 30 megabytes of music. So its a MP3, Sun-droid, GPS, Tides near me, Flashlight, Books, knots, reminder Notes, Alarm clock, spare camera, video, calculator, weather, news, Iheart,etc. We are saving a $175 a month and that's OK. It works fine in town and I can open the apps and it will store a day or two, many will work in Airplane mode. Some will work with Wifi in town. My understanding is it will dial 911 and that will be tested when the opportunity arises. And the Main phone will be used for phone calls and turned off on the trail. Perfect for Kayaking and a "beater upper"
Be wise enough to walk away from the nonsense around you!
