I use my Inreach mostly for communicating with home but like the "scream for help" feature too. I usually have my iPhone with me and have the Earthmate app which uses a Bluetooth connection that lets you use the iPhone keyboard instead of the slow and cumbersome one on the Inreach. I suspect that this issue is much reduced if you use this free app. I have been using an Inreach for 3 -1/2 years with the Earthmate app and have never experienced an uncommanded SOS. YMMV.
